| Although there are no set guidelines regarding the usage of relative versus absolute positioning, the general idea is that absolute positioning is required only when you want to exert a fine degree of control over how content is positioned. This has to do with the fact that absolute positioning allows you to position content down to the exact pixel, whereas relative positioning is much less predictable in terms of how it positions content. This isn't to say that relative positioning can't do a good job of positioning elements on a page; it just means that absolute positioning is more exact. Of course, this also makes absolute positioning potentially more susceptible to changes in screen size, which you can't really control. |
