Jekyll Blog design using Sass

Build your blog with Jekyll

In the previous tutorial, we learnt how to display posts in your Jekyll blog! In this post, we will see how we can add custom styles using Sass in your Jekyll Blog for a better blog design.

Sass is a stylesheet language that is compiled into CSS. It gives you the superpowers to use variables, nested rules, mixins, functions and much more with a fully compatible CSS syntax. To visit the official Sass Documentation to learn more about Sass. Sass can prove to be a very powerful tool for better blog design.

Now let’s start on enabling styles for blog design using Sass.

Edit the _config.yml file

First off, we will let Jekyll know that we intend to use Sass with our website, and so we will add the following to our site’s _config.yml file-

  sass_dir: _scss
  style: compressed

With sass_dir, we specify the directory where we will store our Sass files, which can be included easily later on.

With style, we instruct Jekyll to compress our compiled CSS files, so that it squeezes out every last space and new line break, to decrease the file size, thus decreasing the loading speed.

Creating required directories & files

Now, we will create a _scss directory, to store our Sass files, and also create a css directory, where we will save our style.css which will include all the Sass files, and will be available at css/style.css/ path.

  $ mkdir _scss css
  $ touch _scss/_base.scss css/style.scss

We also created the Sass files in both the folders. Let’s add some content to them.

body {
  background: linear-gradient(to bottom, #fafafa, #f3bc2a);
  height: 100vh;

.card {
  box-shadow: 0px 2px 10px rgba(0, 0, 0, 0.1);

  &:hover {
    box-shadow: 0px 2px 10px rgba(0, 0, 0, 0.3);

a {
  &:hover {
    text-decoration: none;

@import "base"

The ‘---’ lines for the front matter let Jekyll know that we intend to compile this Sass file into CSS, and place it in it’s current folder as <name>.css.

Also, as we specified our Sass directory in _config.yml, the compiler will know where to import the files from.

Now, all we need to do is to link the style.css to our website.

We can do this by adding the following line in _layouts/default.html, preferably in the header.

<link rel="stylesheet" href="css/style.css" />

And now we are done! You can create multiple files in the css directory, import Sass files as needed and link them accordingly.

That’s it for today, hope you learnt something new!

Adios Folks!
