This article discusses the situation where the centering situation is set to a variable total width and a variable content width. (Still centered when resized).

Special note: When setting position:absolute; on an element to set the centering effect, in addition to the css3 method introduced in the blog, you can also use negative margin to center. This solves the compatibility problem, but only Suitable for situations where the width and height are known (because a negative offset is half the width and height of the element). When the width and height change, there is no longer a centered effect.

Child elements in these layouts default to the content width because of their attribute settings.
