Two-Column Layouts
Multicolumn layouts that once required HTML tables are now achievable using CSS alone. Column layouts can be done using floats or absolute positioning (see Chapter 21 for details on both).
Of course, there are endless variations on two-column layouts in terms of page components, measurements, backgrounds, and so forth. The examples in this section represent just a few very basic possibilities. They reveal the general strategy for approaching two-column designs and should serve as a good head start toward implementing your own layouts. It should be noted, however, that they are based on the assumption that the main content column will be longer than the side columns. If your side columns are longer, it may be necessary to make adjustments to the code examples shown here.
