In this example, we'll use Sass's SCSS to pre-compile a mod's CSS.

1. Set your mod to SCSS mode

Select SCSS from the CSS panel dropdown:

2. Add some HTML

Add some HTML to the mod that you want to style. In this example, we'll add a button and some text:

<h2>Hello, World!</h2>
<div class="button">Submit</div>
1
2

This gives a mod with some plain, unstyled text:

3. Add SCSS

Add the SCSS below to your mod. A few features of SCSS highlighted here are:

  • Line 1: Defines a variable called $buttonColor that we reuse on lines 6, 7, and 15.
  • Line 7: Uses SCSS's built-in darken method to generate a color that is 10% darker than $buttonColor.
  • Line 14-16: Nested rule. This is equivalent to writing .button:hover in plain CSS.
  • Line 15: Uses SCSS's built-in lighten method to generate a lighter color.
 





 






 
 
 







$buttonColor: #55acee; 

font-family: sans-serif;

.button {
  background-color: $buttonColor;
  box-shadow: 0px 5px 0px 0px darken($buttonColor, 10%);
  color: white;
  display: inline-block;
  font-size: 18px;
  border-radius: 5px;
  padding: 10px 25px;
  margin: 10px 0;
  &:hover {
    background-color: lighten($buttonColor, 5%);
  }
  &:active {
    transform: translate(0px, 5px);
    -webkit-transform: translate(0px, 5px);
    box-shadow: 0px 1px 0px 0px;
  }
}

This gives us a styled h2 and button:

TIP

Any CSS rules that aren't applied inside of a selector (like line 3 above, font-family: sans-serif;), are automatically applied to the top-level of the mod.

4. Understanding scoping

The mod's final HTML markup in this example looks like the following:

<div id="anymod-kbbdr" kbbdr ...>
  <h2>Hello, World!</h2>
  <div class="button">Submit</div>
</div>
1
2
3
4

The SCSS in this example is pre-compiled to the following CSS when the mod is displayed:

[kbbdr] {
  font-family: sans-serif;
}
[kbbdr] .button {
  background-color: #55acee;
  box-shadow: 0px 5px 0px 0px #2795e9;
  color: white;
  display: inline-block;
  font-size: 18px;
  border-radius: 5px;
  padding: 10px 25px;
  margin: 10px 0;
}
[kbbdr] .button:hover {
  background-color: #6cb7f0;
}
[kbbdr] .button:active {
  transform: translate(0px, 5px);
  -webkit-transform: translate(0px, 5px);
  box-shadow: 0px 1px 0px 0px;
}

By scoping all of the rules to [kbbdr], any rules added within the mod are scoped so that they only apply to the mod itself, and not to the rest of the page.
