CSS3 线性渐变和径向渐变(示例+附图)

线性渐变:ie6以下不兼容

径向渐变:只支持firefox、Chrome和Safari

<div class="circle">

注意:background-image 可以写 background

我自己在网页中写的径向渐变兼容代码 :firefox、chrome、IE10、IE10+、safari(background-image老式写法)兼容

background: rgb(98, 37, 140);
background:-webkit-radial-gradient(circle at top, rgb(160, 114, 193),rgb(98, 37, 140));
background-image: -webkit-gradient(radial,50% 0%,0,50% 55%,90,from(rgb(160, 114, 193)),to(rgb(98, 37, 140)));/* Safari 4-5, Chrome 1-9 */
background:radial-gradient(circle at top, rgb(160, 114, 193),rgb(98, 37, 140));
background:-moz-radial-gradient(circle at top, rgb(160, 114, 193),rgb(98, 37, 140));
background:-ms-radial-gradient(circle at top, rgb(160, 114, 193),rgb(98, 37, 140));

线性渐变兼容代码 :firefox、chrome、IE10、IE10+、safari兼容

background: rgb(247, 100, 14);
background:-webkit-linear-gradient(top, rgb(251, 121, 46) ,rgb(247, 100, 14));/* safari,chrome*/
background:linear-gradient(top, rgb(251, 121, 46) ,rgb(247, 100, 14));
background:-moz-linear-gradient(top, rgb(251, 121, 46) ,rgb(247, 100, 14));
background:-ms-linear-gradient(top, rgb(251, 121, 46) ,rgb(247, 100, 14));
