What is the difference between CSS, SCSS, SASS

CSS (Cascading Style Sheets) is a style sheet language used for describing the presentation of a document

You can see CSS as a classic way for you to add style to your web project. However, people find out some problems when then use CSS, that is why SASS and SCSS are so popular these days.

Sass is an extension of CSS, which support some advanced syntax which we will see below. It supports 2 syntaxes. (you will find some tools have name sass but in face they support 2 syntaxes)

One is SCSS, the code in CSS can be copied to SCSS and it can also work without problems., file using SCSS has extension .scss.

The other one is SASS, which is the original syntax of Sass. SASS is a little different compared with SCSS, it use indention instead of brackets, file using SASS has extension .sass.

Since SCSS is more popular and I will only talk about it in this article, but you should know there is no big difference between them and you can also easily make SASS work in your Django project.

What is the benefit when using SCSS

For example, we have CSS code like this.

nav ul {
  margin: 0;
  padding: 0;
  list-style: none;
nav li {
  display: inline-block;
nav a {
  display: block;
  padding: 6px 12px;
  text-decoration: none;

In SCSS, we can write in this way

nav {
  ul {
    margin: 0;
    padding: 0;
    list-style: none;

  li { display: inline-block; }

  a {
    display: block;
    padding: 6px 12px;
    text-decoration: none;

With fold feature in your text editor, we can fold/unfold SCSS like HTML code, the code is easier to manage.

Another useful feature is variable, if we have CSS like this

body {
  font: 100% Helvetica, sans-serif;
  color: #333;

The SCSS code can be written in this way

$font-stack:    Helvetica, sans-serif;
$primary-color: #333;

body {
  font: 100% $font-stack;
  color: $primary-color;

So in the future, if you want to change the font of your website, you can just do it at the top, no need to search through the whole file.

There are also other useful features in SCSS syntax, if you want to know more, just check the SCSS homepage

What is the SCSS workflow

There are many different ways to make SCSS work in your project, and I will list some here.

  1. You can edit your SCSS files in local env, once you are done, compile them to CSS files (you can use some software here) and push to Git repo.
  2. You can also push your SCSS to Git repo, and compile them to CSS in the deployment stage.

I would recommend using the second method because it would not cause sync problems. But this workflow sometimes requires Devops skill.

What if you already have some CSS files in my Django project

Rome wasn't built in a day

You do not need to delete old CSS files, and start over again, as I said, CSS code can still work in SCSS, so you can change the extension from .css to .scss, and then make the whole workflow work.

After that, you can start using some advanced feature of SCSS to refactor the SCSS file.

You should know, the code below can still work in .scss but you should also know there is a better way to implement it.

nav ul {
  margin: 0;
  padding: 0;
  list-style: none;
nav li {
  display: inline-block;
nav a {
  display: block;
  padding: 6px 12px;
  text-decoration: none;

Start using SCSS in Django project

Here, we plan to use Bootstrap's SCSS code to replace our old bootstrap.css.

Download Bootstrap SCSS source code

First, please go to Bootstrap 4 homepage to Download source, in the package, you will see a directory has name scss, and this directory contains many scss files


The bootstrap.scss is the main entry just like main.js in your projects.

Now copy the files to Django project's static directory, I put them in a directory bootstrap

Install dependency packages

Here we would use two packages, one is django_compressor, the other one is django-libsass, you could use pip to install them.


Next, we config our Django project to make it can handle SCSS in right way.

  1. Add compressor to INSTALLED_APPS
  2. Add compressor.finders.CompressorFinder to STATICFILES_FINDERS
    ('text/x-scss', 'django_libsass.SassCompiler'),

Now setting is done, next, we start to edit our template

Edit template

First, you can delete the old bootstrap.css css link,

Second, we activate compress in the base template so we can use Django tags. Then please use {% compress css %} block to wrap the scss entry file link, please make sure to set type="text/x-scss" here.

{% load compress %}

{% compress css %}
    <link type="text/x-scss" href="{% static 'bootstrap/bootstrap.scss' %}" rel="stylesheet" media="screen">
{% endcompress %}


compress Django tag would process the links in the block. From the text/x-scss, it knows the file use SCSS syntax, and it would use what we config in COMPRESS_PRECOMPILERS to parse the file.

Everything should work fine in debug mode, if you change something in SCSS code, a new CSS file would be generated after you reload the page.

Refactor SCSS code

Now Bootstrap SCSS can work in your project, congratulation!

Let's keep moving to get more.

Try to create a file theme.scss in the project static directory, so the static directory would have something like this.


Edit theme.scss

$primary: red;

@import './bootstrap/bootstrap';

As you can see, in theme.scss, we set @primary variable to red, this is a variable used by Bootstrap SCSS. Then we imported Bootstrap SCSS entry file.

Now you can change your template to use theme.scss instead of the previous bootstrap.scss, then your custom settings would take effect just like this way.

As you can see, your custom config is working, and that is how some Bootstrap theme builder works, it just set some custom SCSS variables and then compile the scss to css.

Deploy SCSS in Django project

We can push our scss files to Git repo and they would be compiled in the deployment stage.

django_compressor provides a Django command for us to convert scss files to css files.

First, please add code below to your settings/


Then in your deployment code, please run command python compress --force after collectstatic, this command would compile scss files.

Advantages and Disadvantages of the django_compressor solution

Let's talk about Advantages first.

  1. It is easy to use, people can get all jobs done with a couple of config codes.
  2. People do not need to touch npm stack, so if you do not want to touch front-end stuff, this is a good option.

Below are the disadvantages

  1. Have bad support if we want to write a theme using SCSS from scratch. (it would be better if the page would be reload automatically if it detects I change my SCSS code.)
  2. Does not support lint feature. (just like flake8 in Python)

npm community already have a good solution to solve above problems, and I strongly recommend you to give it a try*
