Liquid / Fluid Layouts

Liquid CSS layouts are fluid width designs. Some web developers consider the 'Holy Grail' of design as one that

  1. has a fluid center with fixed width sidebars,
  2. allows the center column to appear first in the source,
  3. allows any column to be the tallest,
  4. requires only a single extra div of markup, and
  5. requires very simple CSS, with minimal hacks patches.
