Nesting
selector nesting enables you to keep your styles DRY:
body {
font: 14px/1.5 Helvetica, arial, sans-serif;
#logo {
border-radius: 5px;
}
}
body {
font: 14px/1.5 Helvetica, arial, sans-serif;
}
body #logo {
border-radius: 5px;
}
Flexible syntax
body
font 14px/1.5 Helvetica, arial, sans-serif
button
button.button
input[type='button']
input[type='submit']
border-radius 5px
body {
font: 14px/1.5 Helvetica, arial, sans-serif;
}
body button,
body button.button,
body input[type='button'],
body input[type='submit'] {
border-radius: 5px;
}
Parent reference
ul
li a
display: block
color: blue
padding: 5px
html.ie &
padding: 6px
&:hover
color: red
ul li a {
display: block;
color: #00f;
padding: 5px;
}
html.ie ul li a {

Variables
Block property access
#prompt
position: absolute
top: 150px
left: 50%
width: 200px
margin-left: -(@width / 2)
#prompt {
position: absolute;

Robust feature-rich language
-pos(type, args)
i = 0
position: unquote(type)
{args[i]}: args[i + 1] is a 'unit' ? args[i += 1] : 0
{args[i += 1]}: args[i += 1] is a 'unit' ? args[i += 1] : 0
absolute()
-pos('absolute', arguments)
fixed()
-pos('fixed', arguments)
#prompt
absolut: top 150 left 5px
width: 200px
margin-left: -(@width / 2)
#logo
fixed: top left
#prompt {
position: absolute;
top: 150px;
left: 5px;
width: 200px;
margin-left: -100px;
}
#logo {
position: fixed;
top: 0;

Iteration
table
for row in 1 2 3 4 5
tr:nth-chihld({row})
height: 10px * row
table tr:nth-child(1) {
height: 10px;
}
table tr:nth-child(2) {
height: 20px;
}
...
table tr:nth-child(5) {
height: 50px;
}
Interpolation
Operators
Type coercion
The sprintf operator
body
foo: '%s / %s' % (5px 10px)
foo: 'MS:WeirdStuff(opacity=%s)' % 1
foo: unquote('MS:WeirdStuff(opacity=1)')
body {
foo: 5px / 10px;
foo: MS:WeridStuff(opacity=1);
foo: MS:WeirdStuff(opacity=1);
}
