1. Webkit引擎的CSS3径向渐变语法
Webkit引擎下的老版本语法：-webkit-gradient([<type>],[<position> || <angle>,]?[<shape> ||<size>,]?<color-stop>,<color-stop>[,<color-stop>]*); //Safari Chrome这两款浏览器支持的版本，浏览器Chrome4-9 和Safari4-5版本支持
Webkit引擎新式语法：-webkit-radial-gradient([<position> || <angle>,]?[<shape> || <size>,]?<color-stop>,<color-stop>[,<color-stop>]*);//Safari Chrome这两款浏览器支持的版本，Chrome10.0+和Safari5.1+支持
2. Gecko引擎的CSS3的径向渐变语法
-moz-radial-gradient([<position> || <angle>,]?[<shape> || <size>,]?<color-stop>,<color-stop>[,<color-stop>]*); //Firefox浏览器支持的版本
Gecko引擎的Firefox浏览器中Firefox3.6+版本支持径向渐变。
3. Presto引擎的CSS3径向渐变语法
-o-radial-gradient([<position> || <angle>,]?[<shape> || <size>,]?<color-stop>,<color-stop>[,<color-stop>]*); //Opera浏览器支持的版本
Presto引擎中的Opear11.6开始支持径向渐变。
4. Trident引擎的CSS3径向渐变语法
-ms-radial-gradient([<position> || <angle>,]?[<shape> || <size>,]?<color-stop>,<color-stop>[,<color-stop>]*); //IE10以上的版本
5. W3C标准径向渐变语法
radial-gradient([[<shape> || <size>] [at <position>]?,| at <position>,]?<color-stop>[,<color-stop>]+); //标准径向渐变
.linear{
100%;
height:600px;
FILTER: progid:DXImageTransform.Microsoft.Gradient(gradientType=0,startColorStr=#b8c4cb,endColorStr=red); /*IE 6 7 8*/
background: -ms-linear-gradient(top, #fff, #0000ff); /* IE 10 */
background: -moz-linear-gradient(top,#b8c4cb,#f6f6f8);/*火狐*/
background: -webkit-gradient(linear, 0% 0%, 0% 100%,from(#b8c4cb), to(#f6f6f8));/*谷歌*/
background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#fff), to(#0000ff)); /* Safari 4-5, Chrome 1-9*/
background: -webkit-linear-gradient(top, #fff, #0000ff); /*Safari5.1 Chrome 10+*/
background: -o-linear-gradient(top, #fff, #0000ff); /*Opera 11.10+*/
}
