Ultimate multi-column liquid layouts (em and pixel widths)
by 4 othersThis series of layouts use pixel and em widths and relative positioning, and they work with all the common web browsers including Safari on the iPhone and iPod touch. They're also 'stackable' so you can use multiple column types on the one page.

CSS Variables
Since the release of CSS Level 2 Recommendation ten years ago in may 1998, the Web authors' community has been requesting a way of defining variables in CSS. Variables allow to define stylesheet-wide values identified by a token and usable in all CSS declarations. If a value is often used in a stylesheet - a common example is the value of the color or background-color properties - it's then easy to update the whole stylesheet statically or dynamically modifying just one variable instead of modifying all style rules applying the property/value pair.
w00t!
