Using CSS, JS, images and other assets is straightforward with Jekyll. Place
|
||
them in your site folder and they’ll copy across to the built site.
|
||
|
||
Jekyll sites often use this structure to keep assets organized:
|
||
|
||
```sh
|
||
.
|
||
├── assets
|
||
| ├── css
|
||
| ├── images
|
||
| └── js
|
||
...
|
||
```
|
||
|
||
## Sass
|
||
|
||
The inline styles used in `_includes/navigation.html` is not a best practice,
|
||
let's style the current page with a class instead.
|
||
|
||
{% raw %}
|
||
```liquid
|
||
<nav>
|
||
{% for item in site.data.navigation %}
|
||
<a href="{{ item.link }}" {% if page.url == item.link %}class="current"{% endif %}>{{ item.name }}</a>
|
||
{% endfor %}
|
||
</nav>
|
||
```
|
||
{% endraw %}
|
||
|
||
You could use a standard CSS file for styling, we're going to take it a step
|
||
further by using [Sass](https://sass-lang.com/). Sass is a fantastic extension
|
||
to CSS baked right into Jekyll.
|
||
|
||
First create a Sass file at `/assets/css/styles.scss` with the following
|
||
content:
|
||
|
||
{% raw %}
|
||
```css
|
||
---
|
||
---
|
||
@import "main";
|
||
```
|
||
{% endraw %}
|
||
|
||
The empty front matter at the top tells Jekyll it needs to process the file. The
|
||
`@import "main"` tells Sass to look for a file called `main.scss` in the sass
|
||
directory (`_sass/` by default).
|
||
|
||
At this stage you'll just have a main css file. For larger projects, this is a
|
||
great way to keep your CSS organized.
|
||
|
||
Create `_sass/main.scss` with the following content:
|
||
|
||
```sass
|
||
.current {
|
||
color: green;
|
||
}
|
||
```
|
||
|
||
You'll need to reference the stylesheet in your layout.
|
||
|
||
Open `_layouts/default.html` and add the stylesheet to the `<head>`:
|
||
|
||
{% raw %}
|
||
```liquid
|
||
<!doctype html>
|
||
<html>
|
||
<head>
|
||
<meta charset="utf-8">
|
||
<title>{{ page.title }}</title>
|
||
<link rel="stylesheet" href="/assets/css/styles.css">
|
||
</head>
|
||
<body>
|
||
{% include navigation.html %}
|
||
{{ content }}
|
||
</body>
|
||
</html>
|
||
```
|
||
{% endraw %}
|
||
|
||
Load up <a href="http://localhost:4000" target="_blank" data-proofer-ignore>http://localhost:4000</a>
|
||
and check the active link in the navigation is green.
|
||
|
||
Next we're looking at one of Jekyll's most popular features, blogging.
