Veronica Mars agrees...

CSS is a chore to use in today’s web.

Media Queries

Breakpoints

Grid Frameworks

Vendor-Specific CSS3

Repeating CSS

Everywhere

How do we fix this?

This is where Sass saves the day!

Introducing Sass

Sass is a stylesheet language to pre-process CSS styling.

What’s the big deal?

What can we do with Sass, anyways?

Nested Rules

#main { background-color: #FFCBDB; color: #666666;

}

.warning { background-color: #FF0000; color: #000000;}

#main { background-color: #FFCBDB; color: #666666;}

#main .warning { background-color: #FF0000; color: #000000;}

Nesting allows you to apply the same clean, hierarchy-driven visual makeup of HTML to CSS.

Variables & Functions

$radyellow: #EEAD0E;

#main { background-color: $radyellow; color: darken($radyellow, 30%);}

#main { background-color: #EEAD0E; color: #5e4406;}

Works with any CSS value you can think of!

Operators

#main { $localwidth: 500px; .panel { width: $localwidth/10; }}

#main .panel { width: 100px;}

Computing grid-layouts and element placement is no longer a chore.

Let Sass do the number-crunching for you.

Mixins

@mixin atlantafun() {$atl_peach: #FFD8AD;background-color: $atl_peach;}

body { .view-grid { @include atlantafun(); }}

body .view-grid {background-color: #FFD8AD;}

Mixins define a group of CSS declarations that you can reuse throughout your theme. These

mixins can even include arguments.

Partials

Partials allow for compartmentalizing of your CSS into separate Sass files.

_header.scss
