Css3.0 preemptive check (6): Background-size defines the background size

Originally, we can only change the position and repetition of the background image, but cannot change the size as if we changed the label image. In css3, the image size of the background can be changed.

Sample Code: Background-size: 200px 50px;

Description: 200px indicates the width, and 50px indicates the height.

Currently, only the opera 9.5, Safari 3, and Konqueror browsers are supported. The statement in several browsers is as follows:

-O-Background-size,-WebKit-Background-sizeAnd-Khtml-Background-size.
