title: Convert an HTML site to Jekyll
---

If you're looking for themes for your Jekyll site, you don't have to restrict yourself to existing Jekyll themes. It's pretty easy to convert almost any static HTML files into a Jekyll website.

In many ways, any site that is currently a static site is *already* a Jekyll website. Jekyll just allows you to automate parts of the site (like inserting pages into templates, rendering lists for navigation, generating feeds and sitemaps, and more) as it processes the files.

Understanding how to convert any HTML site into Jekyll templates will open your world to many more options for Jekyll themes. Instead of [searching online for  *Jekyll themes*](https://duckduckgo.com/?q=Jekyll+themes), you can choose from the large variety of HTML templates for your site, quickly Jekyll-ize the HTML templates as you need to, and build the output with Jekyll.

Although websites can have sophisticated features and controls, we'll keep things simple in this tutorial.

## What is a Jekyll Website?

First, let's start with a grounding in the basics. Stripping a Jekyll site down to an extremely basic level will help clarify what happens in a Jekyll site. If you haven't already installed the jekyll gem, [install it]({% link _docs/installation.md %}).

We'll start with a *basic Jekyll site* consisting of three files:

```
├── _config.yml
├── _layouts
│   └── default.html
└── index.md
```

Manually create these three files in a folder called `my_jekyll_site` or whatever suits you the most, and place `default.html` inside a folder named `_layouts`.

```sh
$ touch _config.yml index.md default.html
$ mkdir _layouts && mv default.html _layouts
```

Fire up your favorite editor, and populate the contents of the `default.html` and `index.md` files as follows:

**_config.yml**

```yaml
name: My Jekyll Website
```

**_layouts/default.html**

```html
<!DOCTYPE html>
<html>
  <body>
     {% raw %}{{ content }}{% endraw %}
  </body>
</html>
```

**index.md**

```yaml
---
title: My page
layout: default
---

# {% raw %}{{ page.title }}{% endraw %}

Content is written in [Markdown](https://learnxinyminutes.com/docs/markdown/). Plain text format allows you to focus on your **content**.

<!--
You can use HTML elements in Markdown, such as the comment element, and they won't be affected by a markdown parser. However, if you create an HTML element in your markdown file, you cannot use markdown syntax within that element's contents.
-->
```

Now `cd` to `my_jekyll_site` and serve the site with the built-in server:

```
cd my_jekyll_site
jekyll serve
```

If you have a Gemfile, [use Bundler](/docs/ruby-101/#bundler) by typing `bundle exec jekyll serve` instead.
{: .note .info}

When you serve the site, you get a preview URL such as `http://127.0.0.1:4000/` (which is the same as `http://localhost:4000/`). The site's files are built into the `_site` folder by default.

This is a Jekyll site at the most basic functional level. Here's what is happening:

  * The `_config.yml` file contains settings that Jekyll uses as it processes your site. An empty config file will use default values for building a Jekyll site. For example, to convert [Markdown](https://learnxinyminutes.com/docs/markdown/) to HTML, Jekyll will automatically use the [kramdown Markdown filter](https://rubygems.org/gems/kramdown/), without any need to specify it.
  * Jekyll looks for files with [front matter tags]({% link _docs/front-matter.md %}) (the two sets of dashed lines `---` like those in `index.md`) and processes the files (populating site variables, rendering any [Liquid](https://shopify.github.io/liquid/), and converting Markdown to HTML).
  * Jekyll pushes the content from all pages and posts into the `{% raw %}{{ content }}{% endraw %}` variable in the layout specified (`default`) in the front matter tags.
  * The processed files get written as `.html` files in the `_site` directory.

You can read more about how Jekyll processes the files in [order of Interpretation]({% link _tutorials/orderofinterpretation.md %}).

With this basic understanding of how a Jekyll site works, you can convert almost any HTML theme for Jekyll. The following sections will take you through a step-by-step tutorial to do so.

## 1. Create a template for your default layout

Find your HTML theme and save it as a `default` layout. If you're converting or cloning an existing site, you can right-click the page and view the source code.

For example, suppose you're cloning your company site to create a documentation site with the same branding. Or suppose you have a personal site that you built with HTML and now want to make it a Jekyll site. Get the HTML source code for your site.

{: .note .info}
Regardless of the site, do check the license and make sure you have permission to copy and use the code.

Copy and paste the source code into a file called `default.html`. Put the `default.html` file inside the `_layouts` folder. This will be the default layout template for your pages and posts &mdash; that is, each page or post will use this layout when Jekyll builds the site.

Note that in looking for templates, you want the HTML output of the template. If the template has PHP tags or other dynamic scripts, these dynamic elements will need to be converted to HTML or to [Liquid](https://shopify.github.io/liquid/). Liquid is [Jekyll templating system](/docs/liquid/) to retrieve dynamic content.

Open `default.html` into your browser locally to ensure the site looks and behaves like it does online. You will likely need to adjust CSS, JS, and image paths so they work.

For example, if the paths were relative on the site you copied, you'll need to either download the same assets into your Jekyll site or use absolute paths to the same assets in the cloud. (Syntax such as `src="//` requires a prefix such as `src="http://` to work in your local browser.)

Jekyll provides some [filters](/docs/liquid/filters) to prepend a site URL before path. For example, you could preface your stylesheet like this:

```liquid
{% raw %}{{ "/assets/style.css" | relative_url }}{% endraw %}
```

The `relative_url` filter will prepend the [`baseurl`](https://byparker.com/blog/2014/clearing-up-confusion-around-baseurl/) value from your config file (as`blog` for instance) to the input. This is useful if your site is hosted at a subpath rather than at the root of the domain (for example, `http://mysite.com/blog/`).

You can also use an `absolute_url` filter. This filter will prepend the `url` *and* `baseurl` value to the input:

```liquid
{% raw %}{{ "/assets/style.css" | absolute_url }}{% endraw %}
```

Again, both `url` and `baseurl` can be defined in your site's config file, like this:

```
url: http://mysite.com
baseurl: /blog
```

The result in the output will be `http://mysite.com/blog/assets/style.css`.

Note that the `url` property of any page begins with a forward slash (`/`), so omit this at the end of your `url` or `baseurl` property.

You don't have to prepend filters to link paths like this. You could also use relative links across your entire site. However you decide to code the paths to your assets, make sure they render correctly.

Does your local `default.html` page look good in your browser? Are all images, styles, and other elements showing up correctly? If so, great. Keep going. You can use this template as the layout for all your pages and posts or create as many templates as you need.

In the next section, you'll blank out the content of the layout and replace it with placeholder tags that get populated dynamically with your Jekyll pages.

## 2. Identify the content part of the layout

In `default.html`, find where the page content begins (usually at `h1` or `h2` tags). Replace the title that appears inside these tags with `{% raw %}{{ page.title }}{% endraw %}`.

Remove the content part (keep everything else: navigation menu, sidebar, footer, etc.) and replace it with `{% raw %}{{ content }}{% endraw %}`.

Check the layout again in your browser and make sure you didn't corrupt or alter it up by inadvertently removing a crucial `div` tag or other element. The only change should be to the title and page content, which are now blanked out or showing the placeholder tag.

## 3. Create a couple of files with front matter tags

Create a couple of files (`index.md` and `about.md`) in your root directory.

In your `index.md` file, add some front matter tags containing a `title` and `layout` property, like this:

```yaml
---
title: Home
layout: default
---

Some page content here...
```

Create another page for testing called `about.md` with similar front matter tags.

{: .note .info}
If you don't specify a layout in your pages, Jekyll will simply render that page as an unstyled basic HTML page.

## 4. Add a configuration file

Add a `_config.yml` file in your root directory. In `_config.yml`, you can optionally specify the markdown filter you want. By default, [kramdown](https://kramdown.gettalong.org/) is used (without the need to specify it). If no other filter is specified, your config file will automatically apply the following as a default setting:

```
markdown: kramdown
```

You can also specify [some options](https://kramdown.gettalong.org/converter/html.html) for kramdown to make it behave more like [GitHub Flavored Markdown (GFM)](https://github.github.com/gfm/):

```
kramdown:
 input: GFM
 auto_ids: true
 hard_wrap: false
 syntax_highlighter: rouge
```

## 5. Test your pages

Now run `jekyll serve` and toggle between your `index.html` and `about.html` pages. The default layout should load for both pages.

You've now extracted your content out into separate files and defined a common layout for pages.

You could define any number of layouts you want for pages. Then just identify the layout you want that particular page to use. For example:

```
---
title: Sample page
layout: homepage
---
```

This page would then use the `homepage.html` template in the `_layouts` folder.

You can even set [default front matter tags](/docs/configuration/front-matter-defaults/) for pages, posts, or [collections]({% link _docs/collections.md %}) in your `_config.yml` file so that you don't have to specify the layout in the front matter variables. Anywayd, setting defaults is beyond the scope of this tutorial, let's get back to work.

## 6. Configure site variables

You already configured the page title using `{% raw %}{{ page.title }}{% endraw %}` tags. But there are more `title` tags to populate. Pages also have a [`title`](https://moz.com/learn/seo/title-tag) tag that appears in the browser tab or window. Typically you put the page title followed by the site title here.

In your `default.html` layout, look for the `title` tags below your `head` tags:

```
<title>ACME Website</title>
```

Insert the following site variables:

```
{% raw %}<title>{{ page.title }} | {{ site.title }}</title>{% endraw %}
```

Open `_config.yml` and add a `title` property for your site's name.

```
title: ACME Website
```

Any properties you add in your `_config.yml` file are accessible through the `site` namespace. Similarly, any properties in your page's front matter are accessible through the `page` namespace. Use dot notation after `site` or `page` to access the value.

Stop your Jekyll server with <kbd>Ctrl</kbd> + <kbd>C</kbd> and restart it. Verify that the `title` tags are populating correctly.

{: .note .info}
Every time you modify your config file, you have to restart Jekyll for the changes to take effect. When you modify other files, Jekyll automatically picks up the changes when it rebuilds.

If you have other variables to populate in your site, rinse and repeat.

## 7. Show posts on a page

It's common to show a list of posts on the homepage. First, let's create some posts so that we have something to showcase.

Add some posts in a `_posts` folder following the standard `YYYY-MM-DD-title.md` post format:

  * `2017-01-02-my-first-post.md`
  * `2017-01-15-my-second-post.md`
  * `2017-02-08-my-third-post.md`

In each post, add some basic content:

```
---
title: My First Post
layout: default
---

Some sample content...
```

Now let's create a layout that will display the posts. Create a new file in `_layouts` called `home.html` and add the following logic:

```
---
layout: default
---

{% raw %}{{ content }}
<ul class="myposts">
{% for post in site.posts %}
    <li><a href="{{ post.url }}">{{ post.title}}</a>
    <span class="postDate">{{ post.date | date: "%b %-d, %Y" }}</span>
    </li>
{% endfor %}
</ul>{% endraw %}
```

Create a file called `blog.md` in your root directory and specify the `home` layout:

```
---
title: Blog
layout: home
---
```

In this case, contents of `blog.md` will be pushed into the `{% raw %}{{ content }}{% endraw %}` tag in the `home` layout. Then the `home` layout will be pushed into the `{% raw %}{{ content }}{% endraw %}` tag of the `default` layout.


### How layouts work

When a layout specifies another layout, it means the content of the first layout will be stuffed into the `{% raw %}{{ content }}{% endraw %}` tag of the second layout. As an analogy, think of Russian dolls that fit into each other. Each layout fits into another layout that it specifies.

The following diagram shows how layouts work in Jekyll:

<img src="../../img/jekylllayoutconcept.png" alt="Concept of Jekyll layouts" />

{: .image-description}
In this example, the content from a Markdown document `document.md` that specifies `layout: docs` gets pushed into the `{% raw %}{{ content }}{% endraw %}` tag of the layout file `docs.html`. Because the `docs` layout itself specifies `layout: page`, the content from `docs.html` gets pushed into the `{% raw %}{{ content }}{% endraw %}` tag in the layout file `page.html`. Finally because the `page` layout specifies `layout: default`, the content from `page.html` gets pushed into the `{% raw %}{{ content }}{% endraw %}` tag of the layout file `default.html`.

You don't need multiple layouts. You could just use one: `default`. You have options for how you design your site. In general, it's common to define one layout for pages and another layout for posts, but for both of these layouts to inherit the `default` template (which usually defines the top and bottom parts of the site).

In your browser, go to `blog.html` and see the list of posts.
Note that you don't have to use the method described here. You could have simply added the `for` loop to any page, such as `index.md`, to display these posts. But given that you may have more complex logic for other features, it can be helpful to store your logic in templates separate from the page area where you frequently type your content.

{: .note .info}
At minimum, a layout should contain `{% raw %}{{ content }}{% endraw %}`, which acts as a receiver for the *content* to be rendered.

### For loops

By the way, let's pause here to look at the `for` loop logic a little more closely. [For loops in Liquid](https://shopify.github.io/liquid/tags/iteration/) are one of the most commonly used Liquid tags. *For loops* let you iterate through content in your Jekyll site and build out a result. The `for` loop also has [certain properties available](https://help.shopify.com/themes/liquid/objects/for-loops) (like first or last iteration) based on the loop's position in the loop as well.

We've only scratched the surface of what you can do with `for` loops in retrieving posts. For example, if you wanted to display posts from a specific category, you could do so by adding a `categories` property to your post's front matter and then look in those categories. Further, you could limit the number of results by adding a `limit` property. Here's an example:

```liquid
{% raw %}<ul class="myposts">
{% for post in site.categories.podcasts limit:3 %}
    <li><a href="{{ post.url }}">{{ post.title}}</a>
    <span class="postDate">{{ post.date | date: "%b %-d, %Y" }}</span>
    </li>
{% endfor %}
</ul>{% endraw %}
```

This loop would get the latest three posts that have a category called `podcasts` in the front matter.

## 8. Configure navigation

Now that you've configured posts, let's configure page navigation. Most websites have some navigation either in the sidebar or header area.

In this tutorial, we'll assume you've got a simple list of pages you want to generate. If you only have a handful of pages, you could list them by using a `for` loop to iterate through the `site.pages` object and then order them by a front matter property.

Identify the part of your code where the list of pages appears. Usually this is a `<ul>` element with various child `<li>` elements. Replace the code with the following:

```html
{% raw %}<ul>
  {% assign mypages = site.pages | sort: "order" %}
    {% for page in mypages %}
    <li><a href="{{ page.url | absolute_url }}">{{ page.title }}</a></li>
    {% endfor %}
  </ul>{% endraw %}
```

This example assumes each page would have front matter containing both a `title` and `order` property like this:

```
---
title: My page
order: 2
---
```

Here the `order` property will define how the pages get sorted, with `1` appearing first in the list.

You could also iterate through a list of pages that you maintain in a separate data file. This might be more appropriate if you have a lot of pages, or you have other properties about the pages you want to store.

To manage page links this way, create a folder in your Jekyll project called `_data`. In this folder, create a file called e.g. `navigation.yml` with this content:

```yaml
- title: Sample page 1
  url: /page-1-permalink/

- title: Sample page 2
  url: /page-2-permalink/

- title: Sample page 3
  url: /page-3-permalink/
```

{: .note .info}
If you never wrote any YAML before, you'll get quickly familiar with it. Take a look at [what you can do with YAML](https://learnxinyminutes.com/docs/yaml/).

You can store additional properties for each item in this data file as desired. Arrange the list items in the order you want them to appear.

To print the list of pages from the data file, use code like this:

```html
{% raw %}<ul>
    {% for link in site.data.navigation %}
    <li><a href="{{ link.url }}">{{ link.title }}</a></li>
    {% endfor %}
</ul>{% endraw %}
```

If you have more sophisticated requirements around navigation, such as when building a documentation site, see the [detailed tutorial on navigation](/tutorials/navigation/).

## 9. Simplify your site with includes

Let's suppose your `default.html` file is massive and hard to work with. You can break up your layout by putting some of the HTML code in *include* files.

Add a folder called `_includes` in your root directory. In that folder, add a file there called `sidebar.html`.

Remove your sidebar code from your `default.html` layout and insert it into the `sidebar.html` file.

Where the sidebar code previously existed in `default.html`, pull in your "include" like this:

```liquid
{% raw %}{% include sidebar.html %}{% endraw %}
```

You can break up other elements of your theme like this, such as your header or footer. Then you can apply these common elements to other layout files. This way you won't have duplicate code.

## 10. RSS feed

Your Jekyll site needs an RSS feed. Here's the [basic RSS feed syntax](http://www.w3schools.com/xml/xml_rss.asp). To create an RSS file in Jekyll, create a file called `feed.xml` in your root directory and add the following:

```xml
---
layout: null
---

{% raw %}<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">

    <channel>
        <title>{{ site.title }}</title>
        <link>{{ site.url }}</link>
        <description>{{ site.description }}</description>
        <lastBuildDate>{{ site.time | date_to_rfc822 }}</lastBuildDate>
        {% for post in site.posts %}
        <item>
            <description>
                {{ post.content | escape | truncate: '400' }}
            </description>
            <pubDate>{{ post.date | date_to_rfc822 }}</pubDate>
            <guid>
                {{ post.url | prepend: site.url }}
            </guid>
        </item>
        {% endfor %}
    </channel>
</rss>{% endraw %}
```

Make sure your `_config.yml` file has properties for `title`, `url`, and `description`.

This code uses a `for` loop to look through your last 20 posts. The content from the posts gets escaped and truncated to the last 400 characters using [Liquid filters](https://help.shopify.com/themes/liquid/filters).

In your `default.html` layout, look for a reference to the RSS or Atom feed in your header, and replace it with a reference to the file you just created. For example:

```html
<link rel="alternate" type="application/rss+xml"  href="{% raw %}{{ site.url }}{% endraw %}/feed.xml" title="{% raw %}{{ site.title }}{% endraw %}">
```

You can also auto-generate your posts feed by adding a gem called [`jekyll-feed`](https://help.github.com/articles/atom-rss-feeds-for-github-pages/). This gem will also work on GitHub Pages.

## 11. Add a sitemap

Finally, add a [site map](https://www.sitemaps.org/protocol.html). Create a `sitemap.xml` file in your root directory and add this code:

```xml
---
layout: null
search: exclude
---

{% raw %}<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">

    {% for page in site.pages %}
    <url>
        <loc>{{page.url}}</loc>
        <lastmod>{{site.time | date: '%Y-%m-%d' }}</lastmod>
        <changefreq>daily</changefreq>
        <priority>0.5</priority>
    </url>
    {% endfor %}

    {% for post in site.posts %}
    <url>
        <loc>{{post.url}}</loc>
        <lastmod>{{site.time | date: '%Y-%m-%d' }}</lastmod>
        <changefreq>daily</changefreq>
        <priority>0.5</priority>
    </url>
    {% endfor %}

</urlset>{% endraw %}
```

Again, we're using a `for` loop here to iterate through all posts and pages to add them to the sitemap.

You can also auto-generate your sitemap by adding a gem called [`jekyll-sitemap`](https://help.github.com/articles/sitemaps-for-github-pages/). This gem will also work on GitHub Pages.

## 12. Add external services

For other services you might need (such as contact forms, search, comments, and more), look for third-party services. For example, you might use the following:

  * For comments: [Disqus](https://disqus.com/)
  * For a newsletter: [Tinyletter](https://tinyletter.com/)
  * For contact forms: [Wufoo](https://www.wufoo.com/)
  * For search: [Algolia Docsearch](https://community.algolia.com/docsearch/)

For more details on services for static sites, see the [Third Parties](https://learn.cloudcannon.com/jekyll-third-parties/) list and tutorials from CloudCannon.

Your Jekyll pages consist of HTML, CSS, and JavaScript, so pretty much any code you need to embed will work without a problem.

As you integrate code for these services, note that **if a page in your Jekyll site doesn't have front matter tags, Jekyll won't process any of the content in that page.** The page will just be passed to the `_site` folder when you build your site.

If you do want Jekyll to process some page content (for example, to populate a variable that you define in your site's config file), just add front matter tags to the page. If you don't want any layout applied to the page, specify `layout: null` like this:

```
---
layout: null
---
```

## 13. Conclusion

Although websites can implement more sophisticated features and functionality, we've covered the basics in this tutorial. You now have a fully functional Jekyll site.

To deploy your site, consider using [GitHub Pages](https://pages.github.com/), [Netlify](https://www.netlify.com/), [Amazon AWS S3](https://aws.amazon.com/s3/) using the [s3_website plugin](https://github.com/laurilehmijoki/s3_website), or just FTP your files to your web server.

You can also package your layouts, includes and assets into a Ruby `gem` and [make it a Jekyll theme](/docs/themes/).
