More to Learn★ Include partials

(no asset packer needed)

★ Auto compress CSS files

★ @if, @for, @while syntax

★ “&” as current cascading placeholder

CSS3@import "compass";

.box { background: red; @include border-radius(4px); @include box-shadow( rgba(#ccc, 0.5), 3px, 3px, 5px));}

Helpersh1 { @include ellipsis; @include clearfix;}

a { @include hover-link;}

Frameworks@import "blueprint";

@include blueprint;

.box { @include column(3);}

.remove { background: url("icons.png") 0 -16px;}

Right Aligned.something { background: sprite-image("i/wide.png");}a.next { background: yellow no-repeat sprite-image("i/n.png", 100%); padding-right: 20px;}

Result.something { background: url("i.png");}a.next { background: yellow no-repeat url("i.png") 100% -20px; padding-right: 20px;}

Empty Space.add { background: sprite-image("icons/pl.png");}.remove { background: yellow no-repeat sprite-image("icons/rm.png"); padding: 20px;}

Could be Better.add { background: url("icons.png");}.remove { background: url("icons.png") 0 -16px; padding: 20px;}

Example link

Empty Space.add { background: sprite-image("icons/pl.png");}.remove { background: yellow no-repeat sprite-image("icons/rm.png", 0, 0, 20px); padding: 20px; }

Just Perfect.add { background: url("icons.png");}.remove { background: url("icons.png") 0 -36px; padding: 20px;}

Example link

Sprite Generation★ Sprite image named by directory:

“icons/*.png” > “icons.png”

★ Background position added only if needed

★ Add “no-repeat” by yourself:background: sprite-image("…") no-repeat;
