CSS hack is usually used to ensure compatibility with multiple browsers.

# Test {
Color: red;/* all browsers support */
Color: red! Important;/* supported by Firefox and IE7 */
_ Color: red;/* IE6 supported */
* Color: red;/* IE6 and IE7 */
* + Color: red;/* IE7 supported */
Color: Red \ 9;/* IE6, IE7, and IE8 support */
Color: Red \ 0;/* IE8 supported */
}

When I read www.laiwang.com today, I found that the class attribute of his html contains the following information.

UA-WebKit ua-webkit-535 ua-webkit-535-2 UA-chrome ua-chrome-15 ua-chrome-15-0 ua-chrome-15-0-874 ua-chrome-15-0-874-121 JS

View its JS and find that it is implemented by cssua.

The principle is to use js to add a class containing browser information to HTML.

In this way, you can differentiate browsers in CSS as follows:

. Ua-Chrome
{
Color: red;
}

. Ua-ie
{

Color: blue;
}

There is a similar implementation of http://rafael.adm.br/css_browser_selector/ abroad

Another method to differentiate ie versions

Use

<! -- [If lt IE 7]> <HTML class = "ie IE6"> <! [Endif] -->
<! -- [If IE 7]> <HTML class = "ie IE7"> <! [Endif] -->
<! -- [If IE 8]> <HTML class = "ie IE8"> <! [Endif] -->
<! -- [If IE 9]> <HTML class = "ie ie9"> <! [Endif] -->
<! -- [If (GT ie 9) |! (IE)]> <! --> <HTML> <! -- <! [Endif] -->

Replace<HTML>
