对象选择器 {background:-浏览器前缀-linear-gradient( 起点方向,起点颜色,终点颜色);}

径向渐变的语法

对象选择器 {background:-浏览器前缀-radial-gradient( 起点方向,形状,大小,起点颜色,终点颜色);}

渐变的兼容方法

1、线性渐变

各浏览器前缀

(1)Firefox

(2)Safari , Chrome

(3)Opera 11.10+

兼容IE

2、径向渐变

径向渐变和线性渐变的语法差不多

渐变应用实例

1、径向渐变做大背景

background-color:#4B770A;background-image:-webkit-gradient(radial,50%400,1,50%400,400,from(rgba(255,255,255,0.3)),to(rgba(255,255,255,0)));//仅实现了webkit下的效果

2、蒙版效果

position:fixed;width:100%;height:60px;bottom:0px;content:'';background:-moz-linear-gradient(top,rgba(255,255,255,0)0%,rgba(255,255,255,0.33)33%,rgba(255,255,255,0.73)66%,rgba(255,255,255,1)91%);background:-webkit-gradient(linear,lefttop,leftbottom,color-stop(0%,rgba(255,255,255,0)),color-stop(33%,rgba(255,255,255,0.33)),color-stop(66%,rgba(255,255,255,0.73)),color-stop(91%,rgba(255,255,255,1)));background:-webkit-linear-gradient(top,rgba(255,255,255,0)0%,rgba(255,255,255,0.33)33%,rgba(255,255,255,0.73)66%,rgba(255,255,255,1)91%);background:-o-linear-gradient(top,rgba(255,255,255,0)0%,rgba(255,255,255,0.33)33%,rgba(255,255,255,0.73)66%,rgba(255,255,255,1)91%);background:-ms-linear-gradient(top,rgba(255,255,255,0)0%,rgba(255,255,255,0.33)33%,rgba(255,255,255,0.73)66%,rgba(255,255,255,1)91%);background:linear-gradient(top,rgba(255,255,255,0)0%,rgba(255,255,255,0.73)33%,rgba(255,255,255,0.73)66%,rgba(255,255,255,1)91%);filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#00ffffff',endColorstr='#ffffff',GradientType=0);

3、渐变按钮

.myButton{-moz-box-shadow:inset0px1px0px0px#ffffff;-webkit-box-shadow:inset0px1px0px0px#ffffff;box-shadow:inset0px1px0px0px#ffffff;background:-webkit-gradient(linear,lefttop,leftbottom,color-stop(0.05,#ededed),color-stop(1,#dfdfdf));background:-moz-linear-gradient(top,#ededed5%,#dfdfdf100%);background:-webkit-linear-gradient(top,#ededed5%,#dfdfdf100%);background:-o-linear-gradient(top,#ededed5%,#dfdfdf100%);background:-ms-linear-gradient(top,#ededed5%,#dfdfdf100%);background:linear-gradient(tobottom,#ededed5%,#dfdfdf100%);filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#ededed',endColorstr='#dfdfdf',GradientType=0);background-color:#ededed;-moz-border-radius:6px;-webkit-border-radius:6px;border-radius:6px;border:1pxsolid#dcdcdc;display:inline-block;cursor:pointer;color:#777777;font-family:arial;font-size:15px;font-weight:bold;padding:6px24px;text-decoration:none;text-shadow:0px1px0px#ffffff;margin-top:100px;}.myButton:hover{background:-webkit-gradient(linear,lefttop,leftbottom,color-stop(0.05,#dfdfdf),color-stop(1,#ededed));background:-moz-linear-gradient(top,#dfdfdf5%,#ededed100%);background:-webkit-linear-gradient(top,#dfdfdf5%,#ededed100%);background:-o-linear-gradient(top,#dfdfdf5%,#ededed100%);background:-ms-linear-gradient(top,#dfdfdf5%,#ededed100%);background:linear-gradient(tobottom,#dfdfdf5%,#ededed100%);filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#dfdfdf',endColorstr='#ededed',GradientType=0);background-color:#dfdfdf;}.myButton:active{position:relative;top:1px;}
