Working with Sass in CrafterCMS

Since 4.0.3

CrafterCMS does not directly compile Sass to CSS, but, you can use any UI toolchain you wish to compile to CSS.

When working with Sass in CrafterCMS, you can do the following to compile your Sass code to CSS then commit the built CSS file to Studio:

1. Create a sources folder inside of your project sandbox directory (e.g. CRAFTER_HOME/data/repos/site/PROJECT_NAME/sandbox/sources)

   Please note that the following folders under the sandbox folder are not mapped to the blob stores and developers own these:

   • sources/*

   • static-assets/app/*

   
   

2. Inside the sources folder, you can yarn init a UI toolchain where you yarn add sass and add a build script to your package.json.

   
   

3. Your yarn build should write the compiled output to sandbox/static-assets/css

   
   

4. On your pages, add your stylesheet imports, e.g. <link src=/static-assets/css/style.css rel=stylesheet />

   We recommend adding a comment to indicate that the CSS files are compiled and therefore not to be edited by hand and to let everyone know not to touch that fragment since it’s overwritten by the build script

   
   

5. You can make your changes and build multiple times while previewing, just remember to git add & commit your compiled output into the repo when you’re done with your changes e.g.:

   git add static-assets/css/{Your css files}
   git commit -m "{Add your comment here}"
   

   
   

6. You’d repeat building and committing at the end every time you build your source

Example

Let’s take a look at an example of a project that uses Sass. We will be using a project created using the Wordify Blueprint named MYPROJECT from the marketplace. For this example, we’ll change the color of the social links on the top bar from white to yellow.

Let’s begin by looking at the package.json file in your project:

CRAFTER_HOME/data/repos/site/MYPROJECT/sandbox/sources/scss/package.json

{
  "name": "scss",
  "version": "1.0.0",
  "license": "GPL-3.0-only",
  "scripts": {
    "build": "sass src/style.scss ../../static-assets/css/style.css --no-source-map --style=compressed"
  },
  "devDependencies": {
    "sass": "^1.57.1"
  }
}

The Sass file for the project as seen above can be found under CRAFTER_HOME/data/repos/site/MYPROJECT/sandbox/sources/scss/src/style.scss. Notice that inside the file, it compiles the Sass file into CSS and places the CSS file under CRAFTER_HOME/data/repos/site/MYPROJECT/sandbox/static-assets/css.

This CSS file is imported in the header_include.ftl file under the templates/web/fragments folder of your project:

CRAFTER_HOME/data/repos/site/MYPROJECT/sandbox/templates/web/fragments

<#-- Theme Style: Edit @ sources/scss and build using sass compiler -->
<link rel="stylesheet" href="/static-assets/css/style.css">

In the Sass file, scroll down to .top-bar, and change the color value from $white to $yellow like below:

CRAFTER_HOME/data/repos/site/MYPROJECT/sandbox/sources/scss/src/style.scss

.top-bar {
   background: $primary;
   padding: 10px 0;

   .social, .search-icon {
     a {
       color: $yellow;
       opacity: .5;
       padding: 5px;
       ...

The next step we need to do is to build:

Compile Sass file into CSS

➜  scss git:(master) ✗ yarn add sass
yarn add v1.22.17
[1/4] 🔍  Resolving packages...
[2/4] 🚚  Fetching packages...

➜ scss git:(master) ✗ yarn build
yarn run v1.22.17
$ sass src/style.scss ../../static-assets/css/style.css --no-source-map --style=compressed
✨  Done in 1.02s.

Then git add & commit the CSS file:

Git add & commit the newly compiled style.css file

➜  sandbox git:(master) ✗ git add static-assets/css/style.css
➜  sandbox git:(master) ✗ git commit -m "Edit style.css"
[master 98589a0] Edit style.css
 1 file changed, 1 insertion(+), 1 deletion(-)
 rewrite static-assets/css/style.css (88%)

Preview your project and notice that the social icons in the top bar is now colored yellow
