Allow web page width to adjust automatically

How does "adaptive web design" work? It's not that difficult.

First, add a line ofviewport meta tagat the head of the web page code.

##viewportis the default width and height of the web page. The above line of code means that the width of the web page is equal to the screen width by default (width=device-width), and the original scaling ratio (initial-scale=1) is 1.0, that is, the initial size of the web page occupies the screen 100% of the area.

All major browsers support this setting, including IE9. For those older browsers (mainly IE6, 7, and 8), you need to use

css3-mediaqueries.js.

Do not use absolute width

Because the web page will adjust the layout according to the screen width, absolute width cannot be used The layout also cannot use elements with absolute width. This one is very important.

Specifically, CSS code cannot specify pixel width:

width:xxx px;Only percentage width can be specified:width: xx%; orwidth:auto;
