CSS positioning and floating

CSS provides attributes for positioning and floating that can be used to create column layouts, overlap one part of the layout with another, and accomplish tasks that have typically required multiple tables for years.

The basic idea of positioning is simple. It allows you to define where the element box should appear relative to its normal position, or relative to the parent element, another element, or even the browser window itself. Obviously, this feature is very powerful and surprising. It should come as no surprise that user agents support location in CSS2 far more than anything else.

On the other hand, floating is proposed for the first time in CSS1, which is based on a function that Netscape added in the early days of Web. Floating is not exactly positioning, but it is certainly not a normal flow layout. We will clarify the meaning of floating in later chapters.
