Make your website design easier by using a grid layout. This ensures that your website has lined up elements which make it better for the user experience.
Grid layouts also allow you to evenly space out elements on the page.
You can create the grid framework yourself or you can use a framework generator to make the css for your grid.
Here is a list of CSS grid generators.
NetProtozo CSS Grid Generator
ZURB CSS Grid Builder
At ZURB we use a flexible grid framework that lets us rapidly prototype and implement sites. Recently we'd been creating some variant grids for different widths and gutter sizes so we thought, 'why not just create grids on the fly with a simple tool?'
