渐变一直都是蛮复杂的东东,长长的看不懂
首先先写下IE678支持的渐变滤镜 Code /* IE6789*/ filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#00A3EF', GradientType='0'); 由左向右依次是起始颜色,结束颜色,渐变类型,这个滤镜只能用两种颜色,而且渐变类型只有线性渐变一种,而且只有水平(1)和垂直(0)两种方向 顺便给个网页去色的滤镜: Code html{filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1);} 好了,真正的渐变,这里分成线性渐变和径向渐变来写 线性渐变—— Code /* IE10 Consumer Preview */ background-image: -ms-linear-gradient(top left, #FFFFFF 0%, #00A3EF 100%); /* Mozilla Firefox */ background-image: -moz-linear-gradient(top left, #FFFFFF 0%, #00A3EF 100%); /* Opera */ background-image: -o-linear-gradient(top left, #FFFFFF 0%, #00A3EF 100%); /* Webkit (Safari/Chrome 10) */ background-image: -webkit-gradient(linear, left top, right bottom, color-stop(0, #FFFFFF), color-stop(1, #00A3EF)); /* Webkit (Chrome 11+) */ background-image: -webkit-linear-gradient(top left, #FFFFFF 0%, #00A3EF 100%); /* W3C Markup, IE10 Release Preview */ background-image: linear-gradient(to bottom right, #FFFFFF 0%, #00A3EF 100%); 这样理解,linear是渐变类型,top left是方向起始点坐标0 0/0% 0%(IE10可以用角度45deg),起始色/位置,结束色/位置(如果有多色可以在中间加颜色/位置) 这里再补充一个webkit的新写法—— Code background: -webkit-linear-gradient(left top, #FFFFFF 0%, #00A3EF 100%); 径向渐变—— Code /* IE10 Consumer Preview */ background-image: -ms-radial-gradient(left top, circle farthest-corner, #FFFFFF 0%, #1CBF8D 50%, #00A3EF 100%); /* Mozilla Firefox */ background-image: -moz-radial-gradient(left top, circle farthest-corner, #FFFFFF 0%, #1CBF8D 50%, #00A3EF 100%); /* Opera */ background-image: -o-radial-gradient(left top, circle farthest-corner, #FFFFFF 0%, #1CBF8D 50%, #00A3EF 100%); /* Webkit (Safari/Chrome 10) */ background-image: -webkit-gradient(radial, left top, 0, left top, 1012, color-stop(0, #FFFFFF), color-stop(0.5, #1CBF8D), color-stop(1, #00A3EF)); /* Webkit (Chrome 11+) */ background-image: -webkit-radial-gradient(left top, circle farthest-corner, #FFFFFF 0%, #1CBF8D 50%, #00A3EF 100%); /* W3C Markup, IE10 Release Preview */ background-image: radial-gradient(circle farthest-corner at left top, #FFFFFF 0%, #1CBF8D 50%, #00A3EF 100%); 径向渐变有两种,圆(circle),椭圆(elliptical) 径向渐变比线性多一个渐变大小的属性控制,值可以有closest-side, closest-corner, farthest-corner, farthest-side,其他和线性差不多 注:上面的0%、100%是颜色渲染到的位置,一般的双色0~100%渐变可以不写,如果不写到100%,比如写成0~10%,则可以实现重复渐变10次 |
