CSS Sprites are used mostly for performance purposes
Example, where
z-index
is not useful
z-index
only applies to elements which are positioned (
relative
,
absolute
,
fixed
) Don't use values like 1, 2, 3,... instead use 100, 200, 300
All corners are rounded:
.rounded {
    border-radius: 10px;
}
Only bottom corners are rounded:
.bottom_rounded {
    border-radius: 0 0 10px 10px;
}
Perfectly circled box:
.circle {
    width: 200px;
    height: 200px;
    border-radius: 100px;
    line-height: 200px;
}
Direction rule: top-left, top-right, bottom-right, bottom-left
Stretches the lines so that each line has equal width
An element with
position: relative;
is positioned relative to its normal position. The element will not push any of the content around it.
h1 {
  text-shadow: 3px 0px 3px #ccc;
}
text-shadow: h-shadow v-shadow blur-radius color|none|initial|inherit;
When two margins are touching, the larger of the two margins is used
#header h1 {
    background: url(../images/bg.jpg) top left no-repeat;
    width: 702px;
    height: 100px;
    text-indent: -9999px;
}
