[GitHub Pages](http://pages.github.com) are public web pages for users,
|
||
organizations, and repositories, that are freely hosted on GitHub's
|
||
[github.io]() domain or on a custom domain name of your choice. GitHub Pages are
|
||
powered by Jekyll behind the scenes, so in addition to supporting regular HTML
|
||
content, they’re also a great way to host your Jekyll-powered website for free.
|
||
|
||
## Deploying Jekyll to GitHub Pages
|
||
|
||
GitHub Pages work by looking at certain branches of repositories on GitHub.
|
||
There are two basic types available: user/organization pages and project pages.
|
||
The way to deploy these two types of sites are nearly identical, except for a
|
||
few minor details.
|
||
|
||
### User and Organization Pages
|
||
|
||
User and organization pages live in a special GitHub repository dedicated to
|
||
only the GitHub Pages files. This repository must be named after the account
|
||
name. For example, [@mojombo’s user page
|
||
repository](https://github.com/mojombo/mojombo.github.io) has the name
|
||
`mojombo.github.io`.
|
||
|
||
Content from the `master` branch of your repository will be used to build and
|
||
publish the GitHub Pages site, so make sure your Jekyll site is stored there.
|
||
|
||
<div class="note info">
|
||
<h5>Custom domains do not affect repository names</h5>
|
||
<p>
|
||
GitHub Pages are initially configured to live under the
|
||
<code>username.github.io</code> subdomain, which is why repositories must
|
||
be named this way <strong>even if a custom domain is being used</strong>.
|
||
</p>
|
||
</div>
|
||
|
||
### Project Pages
|
||
|
||
Unlike user and organization Pages, Project Pages are kept in the same
|
||
repository as the project they are for, except that the website content is
|
||
stored in a specially named `gh-pages` branch. The content of this branch will
|
||
be rendered using Jekyll, and the output will become available under a subpath
|
||
of your user pages subdomain, such as `username.github.io/project` (unless a
|
||
custom domain is specified—see below).
|
||
|
||
The Jekyll project repository itself is a perfect example of this branch
|
||
structure—the [master branch]({{ site.repository }}) contains the
|
||
actual software project for Jekyll, however the Jekyll website (that you’re
|
||
looking at right now) is contained in the [gh-pages
|
||
branch]({{ site.repository }}/tree/gh-pages) of the same repository.
|
||
|
||
### Project Page URL Structure
|
||
|
||
Sometimes it's nice to preview your Jekyll site before you push your `gh-pages`
|
||
branch to GitHub. However, the subdirectory-like URL structure GitHub uses for
|
||
Project Pages complicates the proper resolution of URLs. Here is an approach to
|
||
utilizing the GitHub Project Page URL structure (`username.github.io/project-name/`)
|
||
whilst maintaining the ability to preview your Jekyll site locally.
|
||
|
||
1. In `_config.yml`, set the `baseurl` option to `/project-name` -- note the
|
||
leading slash and the **absence** of a trailing slash.
|
||
2. When referencing JS or CSS files, do it like this:
|
||
`{% raw %}{{ site.baseurl }}/path/to/css.css{% endraw %}` -- note the slash
|
||
immediately following the variable (just before "path").
|
||
3. When doing permalinks or internal links, do it like this:
|
||
`{% raw %}{{ site.baseurl }}{{ post.url }}{% endraw %}` -- note that there
|
||
is **no** slash between the two variables.
|
||
4. Finally, if you'd like to preview your site before committing/deploying using
|
||
`jekyll serve`, be sure to pass an **empty string** to the `--baseurl` option,
|
||
so that you can view everything at `localhost:4000` normally (without
|
||
`/project-name` at the beginning): `jekyll serve --baseurl ''`
|
||
|
||
This way you can preview your site locally from the site root on localhost,
|
||
but when GitHub generates your pages from the gh-pages branch all the URLs
|
||
will start with `/project-name` and resolve properly.
