Over the last few weeks we’ve seen how to develop both fixed width and fluid layouts with html and css. Each has its pros as well as its cons. Hybrid layouts are attempts to gain the pros of one type of layout while minimizing some of the cons.
Flexible layouts are created by using relative measurements as opposed to absolute measurements. The question is relative to what? With elastic layouts the measurements are set relative to something internal to the design, usually the size of the type.
