-    query types, e.g. HTTPS (DNS type 65) will be allowed besides the
-    traditional A and AAAA queries when a request is being made via insecure
-    DNS. Has no effect on Secure DNS which always allows additional types.

-resolvers will be used, in order:
-
-1. DNS-over-HTTPS, if the [DNS provider supports it][doh-providers], then
-2. the built-in resolver (enabled on macOS only by default), then
-3. the system's resolver (e.g. `getaddrinfo`).
-
-This can be configured to either restrict usage of non-encrypted DNS
-(`secureDnsMode: "secure"`), or disable DNS-over-HTTPS (`secureDnsMode:
-"off"`). It is also possible to enable or disable the built-in resolver.
-
-To disable insecure DNS, you can specify a `secureDnsMode` of `"secure"`. If you do
-so, you should make sure to provide a list of DNS-over-HTTPS servers to use, in
-case the user's DNS configuration does not include a provider that supports
-DoH.

+# Frameless Window
+
+> Open a window without toolbars, borders, or other graphical "chrome".
+
+A frameless window is a window that has no
+[chrome](https://developer.mozilla.org/en-US/docs/Glossary/Chrome), the parts of
+the window, like toolbars, that are not a part of the web page. These are
+options on the [`BrowserWindow`](browser-window.md) class.
+
+## Create a frameless window
+
+To create a frameless window, you need to set `frame` to `false` in
+[BrowserWindow](browser-window.md)'s `options`:
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ width: 800, height: 600, frame: false })
+win.show()
+```
+
+### Alternatives
+
+There's an alternative way to specify a chromeless window on macOS and Windows.
+Instead of setting `frame` to `false` which disables both the titlebar and window controls,
+you may want to have the title bar hidden and your content extend to the full window size,
+yet still preserve the window controls ("traffic lights" on macOS) for standard window actions.
+You can do so by specifying the `titleBarStyle` option:
+
+#### `hidden`
+
+Results in a hidden title bar and a full size content window. On macOS, the title bar still has the standard window controls (“traffic lights”) in the top left.
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ titleBarStyle: 'hidden' })
+win.show()
+```
+
+### Alternatives on macOS
+
+#### `hiddenInset`
+
+Results in a hidden title bar with an alternative look where the traffic light buttons are slightly more inset from the window edge.
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ titleBarStyle: 'hiddenInset' })
+win.show()
+```
+
+#### `customButtonsOnHover`
+
+Uses custom drawn close, and miniaturize buttons that display
+when hovering in the top left of the window. The fullscreen button
+is not available due to restrictions of frameless windows as they
+interface with Apple's macOS window masks. These custom buttons prevent
+issues with mouse events that occur with the standard window toolbar buttons.
+This option is only applicable for frameless windows.
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ titleBarStyle: 'customButtonsOnHover', frame: false })
+win.show()
+```
+
+## Windows Control Overlay
+
+When using a frameless window in conjuction with `win.setWindowButtonVisibility(true)` on macOS, using one of the `titleBarStyle`s as described above so
+that the traffic lights are visible, or using `titleBarStyle: hidden` on Windows, you can access the Window Controls Overlay [JavaScript APIs][overlay-javascript-apis] and
+[CSS Environment Variables][overlay-css-env-vars] by setting the `titleBarOverlay` option to true. Specifying `true` will result in an overlay with default system colors.
+
+On Windows, you can also specify the color of the overlay and its symbols by setting `titleBarOverlay` to an object with the options `color` and `symbolColor`. If an option is not specified, the color will default to its system color for the window control buttons:
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({
+  titleBarStyle: 'hidden',
+  titleBarOverlay: true
+})
+win.show()
+```
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({
+  titleBarStyle: 'hidden',
+  titleBarOverlay: {
+    color: '#2f3241',
+    symbolColor: '#74b1be'
+  }
+})
+win.show()
+```
+
+## Transparent window
+
+By setting the `transparent` option to `true`, you can also make the frameless
+window transparent:
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ transparent: true, frame: false })
+win.show()
+```
+
+### Limitations
+
+* You can not click through the transparent area. We are going to introduce an
+  API to set window shape to solve this, see
+  [our issue](https://github.com/electron/electron/issues/1335) for details.
+* Transparent windows are not resizable. Setting `resizable` to `true` may make
+  a transparent window stop working on some platforms.
+* The `blur` filter only applies to the web page, so there is no way to apply
+  blur effect to the content below the window (i.e. other applications open on
+  the user's system).
+* The window will not be transparent when DevTools is opened.
+* On Windows operating systems,
+  * transparent windows will not work when DWM is
+  disabled.
+  * transparent windows can not be maximized using the Windows system menu or by double clicking the title bar. The reasoning behind this can be seen on [this pull request](https://github.com/electron/electron/pull/28207).
+* On Linux, users have to put `--enable-transparent-visuals --disable-gpu` in
+  the command line to disable GPU and allow ARGB to make transparent window,
+  this is caused by an upstream bug that [alpha channel doesn't work on some
+  NVidia drivers](https://bugs.chromium.org/p/chromium/issues/detail?id=369209) on
+  Linux.
+* On Mac, the native window shadow will not be shown on a transparent window.
+
+## Click-through window
+
+To create a click-through window, i.e. making the window ignore all mouse
+events, you can call the [win.setIgnoreMouseEvents(ignore)][ignore-mouse-events]
+API:
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow()
+win.setIgnoreMouseEvents(true)
+```
+
+### Forwarding
+
+Ignoring mouse messages makes the web page oblivious to mouse movement, meaning
+that mouse movement events will not be emitted. On Windows operating systems an
+optional parameter can be used to forward mouse move messages to the web page,
+allowing events such as `mouseleave` to be emitted:
+
+```javascript
+const { ipcRenderer } = require('electron')
+const el = document.getElementById('clickThroughElement')
+el.addEventListener('mouseenter', () => {
+  ipcRenderer.send('set-ignore-mouse-events', true, { forward: true })
+})
+el.addEventListener('mouseleave', () => {
+  ipcRenderer.send('set-ignore-mouse-events', false)
+})
+
+// Main process
+const { ipcMain } = require('electron')
+ipcMain.on('set-ignore-mouse-events', (event, ...args) => {
+  BrowserWindow.fromWebContents(event.sender).setIgnoreMouseEvents(...args)
+})
+```
+
+This makes the web page click-through when over `el`, and returns to normal
+outside it.
+
+## Draggable region
+
+By default, the frameless window is non-draggable. Apps need to specify
+`-webkit-app-region: drag` in CSS to tell Electron which regions are draggable
+(like the OS's standard titlebar), and apps can also use
+`-webkit-app-region: no-drag` to exclude the non-draggable area from the
+ draggable region. Note that only rectangular shapes are currently supported.
+
+Note: `-webkit-app-region: drag` is known to have problems while the developer tools are open. See this [GitHub issue](https://github.com/electron/electron/issues/3647) for more information including a workaround.
+
+To make the whole window draggable, you can add `-webkit-app-region: drag` as
+`body`'s style:
+
+```html
+<body style="-webkit-app-region: drag">
+</body>
+```
+
+And note that if you have made the whole window draggable, you must also mark
+buttons as non-draggable, otherwise it would be impossible for users to click on
+them:
+
+```css
+button {
+  -webkit-app-region: no-drag;
+}
+```
+
+If you're only setting a custom titlebar as draggable, you also need to make all
+buttons in titlebar non-draggable.
+
+## Text selection
+
+In a frameless window the dragging behavior may conflict with selecting text.
+For example, when you drag the titlebar you may accidentally select the text on
+the titlebar. To prevent this, you need to disable text selection within a
+draggable area like this:
+
+```css
+.titlebar {
+  -webkit-user-select: none;
+  -webkit-app-region: drag;
+}
+```
+
+## Context menu
+
+On some platforms, the draggable area will be treated as a non-client frame, so
+when you right click on it a system menu will pop up. To make the context menu
+behave correctly on all platforms you should never use a custom context menu on
+draggable areas.

+# Automated Testing with a Custom Driver
+
+To write automated tests for your Electron app, you will need a way to "drive" your application. [Spectron](https://electronjs.org/spectron) is a commonly-used solution which lets you emulate user actions via [WebDriver](https://webdriver.io/). However, it's also possible to write your own custom driver using node's builtin IPC-over-STDIO. The benefit of a custom driver is that it tends to require less overhead than Spectron, and lets you expose custom methods to your test suite.
+
+To create a custom driver, we'll use Node.js' [child_process](https://nodejs.org/api/child_process.html) API. The test suite will spawn the Electron process, then establish a simple messaging protocol:
+
+```js
+const childProcess = require('child_process')
+const electronPath = require('electron')
+
+// spawn the process
+const env = { /* ... */ }
+const stdio = ['inherit', 'inherit', 'inherit', 'ipc']
+const appProcess = childProcess.spawn(electronPath, ['./app'], { stdio, env })
+
+// listen for IPC messages from the app
+appProcess.on('message', (msg) => {
+  // ...
+})
+
+// send an IPC message to the app
+appProcess.send({ my: 'message' })
+```
+
+From within the Electron app, you can listen for messages and send replies using the Node.js [process](https://nodejs.org/api/process.html) API:
+
+```js
+// listen for IPC messages from the test suite
+process.on('message', (msg) => {
+  // ...
+})
+
+// send an IPC message to the test suite
+process.send({ my: 'message' })
+```
+
+We can now communicate from the test suite to the Electron app using the `appProcess` object.
+
+For convenience, you may want to wrap `appProcess` in a driver object that provides more high-level functions. Here is an example of how you can do this:
+
+```js
+class TestDriver {
+  constructor ({ path, args, env }) {
+    this.rpcCalls = []
+
+    // start child process
+    env.APP_TEST_DRIVER = 1 // let the app know it should listen for messages
+    this.process = childProcess.spawn(path, args, { stdio: ['inherit', 'inherit', 'inherit', 'ipc'], env })
+
+    // handle rpc responses
+    this.process.on('message', (message) => {
+      // pop the handler
+      const rpcCall = this.rpcCalls[message.msgId]
+      if (!rpcCall) return
+      this.rpcCalls[message.msgId] = null
+      // reject/resolve
+      if (message.reject) rpcCall.reject(message.reject)
+      else rpcCall.resolve(message.resolve)
+    })
+
+    // wait for ready
+    this.isReady = this.rpc('isReady').catch((err) => {
+      console.error('Application failed to start', err)
+      this.stop()
+      process.exit(1)
+    })
+  }
+
+  // simple RPC call
+  // to use: driver.rpc('method', 1, 2, 3).then(...)
+  async rpc (cmd, ...args) {
+    // send rpc request
+    const msgId = this.rpcCalls.length
+    this.process.send({ msgId, cmd, args })
+    return new Promise((resolve, reject) => this.rpcCalls.push({ resolve, reject }))
+  }
+
+  stop () {
+    this.process.kill()
+  }
+}
+```
+
+In the app, you'd need to write a simple handler for the RPC calls:
+
+```js
+if (process.env.APP_TEST_DRIVER) {
+  process.on('message', onMessage)
+}
+
+async function onMessage ({ msgId, cmd, args }) {
+  let method = METHODS[cmd]
+  if (!method) method = () => new Error('Invalid method: ' + cmd)
+  try {
+    const resolve = await method(...args)
+    process.send({ msgId, resolve })
+  } catch (err) {
+    const reject = {
+      message: err.message,
+      stack: err.stack,
+      name: err.name
+    }
+    process.send({ msgId, reject })
+  }
+}
+
+const METHODS = {
+  isReady () {
+    // do any setup needed
+    return true
+  }
+  // define your RPC-able methods here
+}
+```
+
+Then, in your test suite, you can use your test-driver as follows:
+
+```js
+const test = require('ava')
+const electronPath = require('electron')
+
+const app = new TestDriver({
+  path: electronPath,
+  args: ['./app'],
+  env: {
+    NODE_ENV: 'test'
+  }
+})
+test.before(async t => {
+  await app.isReady
+})
+test.after.always('cleanup', async t => {
+  await app.stop()
+})
+```

-# Automated Testing
-
-Test automation is an efficient way of validating that your application code works as intended.
-While Electron doesn't actively maintain its own testing solution, this guide will go over a couple
-ways you can run end-to-end automated tests on your Electron app.
-
-## Using the WebDriver interface
-
-From [ChromeDriver - WebDriver for Chrome][chrome-driver]:
-
-> WebDriver is an open source tool for automated testing of web apps across many
-> browsers. It provides capabilities for navigating to web pages, user input,
-> JavaScript execution, and more. ChromeDriver is a standalone server which
-> implements WebDriver's wire protocol for Chromium. It is being developed by
-> members of the Chromium and WebDriver teams.
-
-There are a few ways that you can set up testing using WebDriver.
-
-### With WebdriverIO
-
-[WebdriverIO](https://webdriver.io/) (WDIO) is a test automation framework that provides a
-Node.js package for testing with WebDriver. Its ecosystem also includes various plugins
-(e.g. reporter and services) that can help you put together your test setup.
-
-#### Install the testrunner
-
-First you need to run the WebdriverIO starter toolkit in your project root directory:
-
-```sh npm2yarn
-npx wdio . --yes
-```
-
-This installs all necessary packages for you and generates a `wdio.conf.js` configuration file.
-
-#### Connect WDIO to your Electron app
-
-Update the capabilities in your configuration file to point to your Electron app binary:
-
-```javascript title='wdio.conf.js'
-export.config = {
-  // ...
-  capabilities: [{
-    browserName: 'chrome',
-    'goog:chromeOptions': {
-      binary: '/path/to/your/electron/binary', // Path to your Electron binary.
-      args: [/* cli arguments */] // Optional, perhaps 'app=' + /path/to/your/app/
-    }
-  }]
-  // ...
-}
-```
-
-#### Run your tests
-
-To run your tests:
-
-```sh
-$ npx wdio run wdio.conf.js
-```
-
-[chrome-driver]: https://sites.google.com/chromium.org/driver/
-
-### With Selenium
-
-[Selenium](https://www.selenium.dev/) is a web automation framework that
-exposes bindings to WebDriver APIs in many languages. Their Node.js bindings
-are available under the `selenium-webdriver` package on NPM.
-
-#### Run a ChromeDriver server
-
-In order to use Selenium with Electron, you need to download the `electron-chromedriver`
-binary, and run it:
-
-```sh npm2yarn
-npm install --save-dev electron-chromedriver
-./node_modules/.bin/chromedriver
-Starting ChromeDriver (v2.10.291558) on port 9515
-Only local connections are allowed.
-```
-
-Remember the port number `9515`, which will be used later.
-
-#### Connect Selenium to ChromeDriver
-
-Next, install Selenium into your project:
-
-```sh npm2yarn
-npm install --save-dev selenium-webdriver
-```
-
-Usage of `selenium-webdriver` with Electron is the same as with
-normal websites, except that you have to manually specify how to connect
-ChromeDriver and where to find the binary of your Electron app:
-
-```js title='test.js'
-const webdriver = require('selenium-webdriver')
-const driver = new webdriver.Builder()
-  // The "9515" is the port opened by ChromeDriver.
-  .usingServer('http://localhost:9515')
-  .withCapabilities({
-    'goog:chromeOptions': {
-      // Here is the path to your Electron binary.
-      binary: '/Path-to-Your-App.app/Contents/MacOS/Electron'
-    }
-  })
-  .forBrowser('chrome') // note: use .forBrowser('electron') for selenium-webdriver <= 3.6.0
-  .build()
-driver.get('http://www.google.com')
-driver.findElement(webdriver.By.name('q')).sendKeys('webdriver')
-driver.findElement(webdriver.By.name('btnG')).click()
-driver.wait(() => {
-  return driver.getTitle().then((title) => {
-    return title === 'webdriver - Google Search'
-  })
-}, 1000)
-driver.quit()
-```
-
-## Using a custom test driver
-
-It's also possible to write your own custom driver using Node.js' built-in IPC-over-STDIO.
-Custom test drivers require you to write additional app code, but have lower overhead and let you
-expose custom methods to your test suite.
-
-To create a custom driver, we'll use Node.js' [`child_process`](https://nodejs.org/api/child_process.html) API.
-The test suite will spawn the Electron process, then establish a simple messaging protocol:
-
-```js title='testDriver.js'
-const childProcess = require('child_process')
-const electronPath = require('electron')
-
-// spawn the process
-const env = { /* ... */ }
-const stdio = ['inherit', 'inherit', 'inherit', 'ipc']
-const appProcess = childProcess.spawn(electronPath, ['./app'], { stdio, env })
-
-// listen for IPC messages from the app
-appProcess.on('message', (msg) => {
-  // ...
-})
-
-// send an IPC message to the app
-appProcess.send({ my: 'message' })
-```
-
-From within the Electron app, you can listen for messages and send replies using the Node.js
-[`process`](https://nodejs.org/api/process.html) API:
-
-```js title='main.js'
-// listen for messages from the test suite
-process.on('message', (msg) => {
-  // ...
-})
-
-// send a message to the test suite
-process.send({ my: 'message' })
-```
-
-We can now communicate from the test suite to the Electron app using the `appProcess` object.
-
-For convenience, you may want to wrap `appProcess` in a driver object that provides more
-high-level functions. Here is an example of how you can do this. Let's start by creating
-a `TestDriver` class:
-
-```js title='testDriver.js'
-class TestDriver {
-  constructor ({ path, args, env }) {
-    this.rpcCalls = []
-
-    // start child process
-    env.APP_TEST_DRIVER = 1 // let the app know it should listen for messages
-    this.process = childProcess.spawn(path, args, { stdio: ['inherit', 'inherit', 'inherit', 'ipc'], env })
-
-    // handle rpc responses
-    this.process.on('message', (message) => {
-      // pop the handler
-      const rpcCall = this.rpcCalls[message.msgId]
-      if (!rpcCall) return
-      this.rpcCalls[message.msgId] = null
-      // reject/resolve
-      if (message.reject) rpcCall.reject(message.reject)
-      else rpcCall.resolve(message.resolve)
-    })
-
-    // wait for ready
-    this.isReady = this.rpc('isReady').catch((err) => {
-      console.error('Application failed to start', err)
-      this.stop()
-      process.exit(1)
-    })
-  }
-
-  // simple RPC call
-  // to use: driver.rpc('method', 1, 2, 3).then(...)
-  async rpc (cmd, ...args) {
-    // send rpc request
-    const msgId = this.rpcCalls.length
-    this.process.send({ msgId, cmd, args })
-    return new Promise((resolve, reject) => this.rpcCalls.push({ resolve, reject }))
-  }
-
-  stop () {
-    this.process.kill()
-  }
-}
-
-module.exports = { TestDriver };
-```
-
-In your app code, can then write a simple handler to receive RPC calls:
-
-```js title='main.js'
-const METHODS = {
-  isReady () {
-    // do any setup needed
-    return true

+
+### 3. Connect to ChromeDriver
+
+The usage of `selenium-webdriver` with Electron is the same with

+
+```javascript
+const webdriver = require('selenium-webdriver')
+
+const driver = new webdriver.Builder()
+  // The "9515" is the port opened by chrome driver.
+  .usingServer('http://localhost:9515')

+    }
+  })
+  .forBrowser('chrome') // note: use .forBrowser('electron') for selenium-webdriver <= 3.6.0
+  .build()
+
+driver.get('http://www.google.com')

-# Window Customization
-
-The `BrowserWindow` module is the foundation of your Electron application, and it exposes
-many APIs that can change the look and behavior of your browser windows. In this
-tutorial, we will be going over the various use-cases for window customization on
-macOS, Windows, and Linux.
-
-## Create frameless windows
-
-A frameless window is a window that has no [chrome]. Not to be confused with the Google
-Chrome browser, window _chrome_ refers to the parts of the window (e.g. toolbars, controls)
-that are not a part of the web page.
-
-To create a frameless window, you need to set `frame` to `false` in the `BrowserWindow`
-constructor.
-
-```javascript title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ frame: false })
-```
-
-## Apply custom title bar styles _macOS_ _Windows_
-
-Title bar styles allow you to hide most of a BrowserWindow's chrome while keeping the
-system's native window controls intact and can be configured with the `titleBarStyle`
-option in the `BrowserWindow` constructor.
-
-Applying the `hidden` title bar style results in a hidden title bar and a full-size
-content window.
-
-```javascript title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'hidden' })
-```
-
-### Control the traffic lights _macOS_
-
-On macOS, applying the `hidden` title bar style will still expose the standard window
-controls (“traffic lights”) in the top left.
-
-#### Customize the look of your traffic lights _macOS_
-
-The `customButtonsOnHover` title bar style will hide the traffic lights until you hover
-over them. This is useful if you want to create custom traffic lights in your HTML but still
-use the native UI to control the window.
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'customButtonsOnHover' })
-```
-
-#### Customize the traffic light position _macOS_
-
-To modify the position of the traffic light window controls, there are two configuration
-options available.
-
-Applying `hiddenInset` title bar style will shift the vertical inset of the traffic lights
-by a fixed amount.
-
-```javascript title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'hiddenInset' })
-```
-
-If you need more granular control over the positioning of the traffic lights, you can pass
-a set of coordinates to the `trafficLightPosition` option in the `BrowserWindow`
-constructor.
-
-```javascript title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({
-  titleBarStyle: 'hidden',
-  trafficLightPosition: { x: 10, y: 10 }
-})
-```
-
-#### Show and hide the traffic lights programmatically _macOS_
-
-You can also show and hide the traffic lights programmatically from the main process.
-The `win.setWindowButtonVisibility` forces traffic lights to be show or hidden depending
-on the value of its boolean parameter.
-
-```javascript title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow()
-// hides the traffic lights
-win.setWindowButtonVisibility(false)
-```
-
-> Note: Given the number of APIs available, there are many ways of achieving this. For instance,
-> combining `frame: false` with `win.setWindowButtonVisibility(true)` will yield the same
-> layout outcome as setting `titleBarStyle: 'hidden'`.
-
-## Window Controls Overlay _macOS_ _Windows_
-
-The [Window Controls Overlay API] is a web standard that gives web apps the ability to
-customize their title bar region when installed on desktop. Electron exposes this API
-through the `BrowserWindow` constructor option `titleBarOverlay`.
-
-This option only works whenever a custom `titlebarStyle` is applied on macOS or Windows.
-When `titleBarOverlay` is enabled, the window controls become exposed in their default
-position, and DOM elements cannot use the area underneath this region.
-
-The `titleBarOverlay` option accepts two different value formats.
-
-Specifying `true` on either platform will result in an overlay region with default
-system colors:
-
-```javascript title='main.js'
-// on macOS or Windows
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({
-  titleBarStyle: 'hidden',
-  titleBarOverlay: true
-})
-```
-
-On Windows, you can also specify the color of the overlay and its symbols by setting
-`titleBarOverlay` to an object with the `color` and `symbolColor` properties. If an option
-is not specified, the color will default to its system color for the window control buttons:
-
-```javascript title='main.js'
-// on Windows
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({
-  titleBarStyle: 'hidden',
-  titleBarOverlay: {
-    color: '#2f3241',
-    symbolColor: '#74b1be'
-  }
-})
-```
-
-> Note: Once your title bar overlay is enabled from the main process, you can access the overlay's
-> color and dimension values from a renderer using a set of readonly
-> [JavaScript APIs][overlay-javascript-apis] and [CSS Environment Variables][overlay-css-env-vars].
-
-## Create transparent windows
-
-By setting the `transparent` option to `true`, you can make a fully transparent window.
-
-```javascript title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ transparent: true })
-```
-
-### Limitations
-
-* You cannot click through the transparent area. See
-  [#1335](https://github.com/electron/electron/issues/1335) for details.
-* Transparent windows are not resizable. Setting `resizable` to `true` may make
-  a transparent window stop working on some platforms.
-* The CSS [`blur()`] filter only applies to the window's web contents, so there is no way to apply
-  blur effect to the content below the window (i.e. other applications open on
-  the user's system).
-* The window will not be transparent when DevTools is opened.
-* On _Windows_:
-  * Transparent windows will not work when DWM is disabled.
-  * Transparent windows can not be maximized using the Windows system menu or by double
-  clicking the title bar. The reasoning behind this can be seen on
-  PR [#28207](https://github.com/electron/electron/pull/28207).
-* On _macOS_:
-  * The native window shadow will not be shown on a transparent window.
-
-## Create click-through windows
-
-To create a click-through window, i.e. making the window ignore all mouse
-events, you can call the [win.setIgnoreMouseEvents(ignore)][ignore-mouse-events]
-API:
-
-```javascript title='main.js'
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow()
-win.setIgnoreMouseEvents(true)
-```
-
-### Forward mouse events _macOS_ _Windows_
-
-Ignoring mouse messages makes the web contents oblivious to mouse movement,
-meaning that mouse movement events will not be emitted. On Windows and macOS, an
-optional parameter can be used to forward mouse move messages to the web page,
-allowing events such as `mouseleave` to be emitted:
-
-```javascript title='main.js'
-const { BrowserWindow, ipcMain } = require('electron')
-const path = require('path')
-
-const win = new BrowserWindow({
-  webPreferences: {
-    preload: path.join(__dirname, 'preload.js')
-  }
-})
-
-ipcMain.on('set-ignore-mouse-events', (event, ...args) => {
-  const win = BrowserWindow.fromWebContents(event.sender)
-  win.setIgnoreMouseEvents(...args)
-})
-```
-
-```javascript title='preload.js'
-window.addEventListener('DOMContentLoaded', () => {
-  const el = document.getElementById('clickThroughElement')
-  el.addEventListener('mouseenter', () => {
-    ipcRenderer.send('set-ignore-mouse-events', true, { forward: true })
-  })
-  el.addEventListener('mouseleave', () => {
-    ipcRenderer.send('set-ignore-mouse-events', false)
-  })
-})
-```
-
-This makes the web page click-through when over the `#clickThroughElement` element,
-and returns to normal outside it.
-
-## Set custom draggable region
-
-By default, the frameless window is non-draggable. Apps need to specify
-`-webkit-app-region: drag` in CSS to tell Electron which regions are draggable
-(like the OS's standard titlebar), and apps can also use
-`-webkit-app-region: no-drag` to exclude the non-draggable area from the
- draggable region. Note that only rectangular shapes are currently supported.
-
-To make the whole window draggable, you can add `-webkit-app-region: drag` as
-`body`'s style:
-
-```css title='styles.css'
-body {
-  -webkit-app-region: drag;
-}
-```
-
-And note that if you have made the whole window draggable, you must also mark
-buttons as non-draggable, otherwise it would be impossible for users to click on
-them:
-
-```css title='styles.css'
-button {
-  -webkit-app-region: no-drag;
-}
-```
-
-If you're only setting a custom titlebar as draggable, you also need to make all
-buttons in titlebar non-draggable.
-
-### Tip: disable text selection
-
-When creating a draggable region, the dragging behavior may conflict with text selection.
-For example, when you drag the titlebar, you may accidentally select its text contents.
-To prevent this, you need to disable text selection within a draggable area like this:
-
-```css
-.titlebar {
-  -webkit-user-select: none;
-  -webkit-app-region: drag;
-}
-```
-
-### Tip: disable context menus
-
-On some platforms, the draggable area will be treated as a non-client frame, so
-when you right click on it, a system menu will pop up. To make the context menu
-behave correctly on all platforms, you should never use a custom context menu on
-draggable areas.
