Especially if you’ve used Sass.

Sass takes everything that’s missing from CSS

and puts it into CSS.

h1 { color: #000; font: 16px/1.6 Georgia; margin: 0;}

Things like…

h1 { color: $logo-color; font: 16px/1.6 Georgia; margin: 0;}

Variables

h1 { color: #000; font: 16px/1.6 Georgia; margin: 0; a { display: block; width: 100px; height: 50px; }}

Nesting

h1 { color: #000; font: 16px/1.6 Georgia; margin: 0; &.new { color: red; }}

The Ampersand

h1 { color: #000; font: 16px/1.6 Georgia; margin: 0;}h2 { @extend h1; font-size: 14px;}

Selector Inheritance

h1 { color: #000; font: 16px/1.6 Georgia; margin: $default_margin * 2;}

Calculations

h1 { color: lighten(#000, 25%); font: 16px/1.6 Georgia; margin: 0;}

Color Manipulation

h1 { color: #000; font: 16px/1.6 Georgia; margin: 0; @include border-radius(4px);}

Mixins

And so, so much more.

Sass does not replace CSS.

Sass does not replace CSS.Sass makes CSS.

Three more thingsbefore we play…

What’s ?http://compass-style.org

makes using the latest CSS features super easy

Compass is not Sass, but they are oen grouped together.

Don’t be afraid.

The Command Line3

Let’s look at some code!

NOTE: At this point, we switched to a

live code demonstration (with Sass/

SCSS on the left and auto-updating

compiled CSS on the right).

See the code:https://github.com/jayroh/sass-harvard

Note that the code samples are stored within the same !le, but on different branches. Here are the direct links to each branch:

Ampersand (Sass/SCSS)Calculations (Sass/SCSS)

Colors (Sass/SCSS)Compass (Sass/SCSS)

Extend (Sass/SCSS)Loops (Sass/SCSS)

Mixins (Sass/SCSS)Nesting (Sass/SCSS)Partials (Sass/SCSS)Responsive (Sass/SCSS)Sprites (Sass/SCSS)Variables (Sass/SCSS)

Who are these guys?
