A DIV element is an element that provides a structure and a background for the contents of a chunk (Block-level) within an HTML document.

First, the high reliance on CSS makes web design more complex. Relative to the table layout in HTML4.0 (table), css+div although not high, but at least more complex than the table positioning, even for the site Design Master is very easy to have problems, not to mention beginners, which to some extent, the impact of XHTML web design language Popular application.

Because for search engine, website structure, content, related website link and so on factor is always the most important index of website optimization.
