实例代码:
<!doctype html> <html> <head> <meta charset="UTF-8" /> <title>gradient 兼容性处理</title> <style type="text/css"> * { margin: 0; padding: 0; } .parent { width: 400px; height: 400px; margin: 100px; font-size: 20px; color: #FF0000; border: 1px solid red; background: #000000; background: -moz-linear-gradient(top, #000000 0%, #ffffff 100%); background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #000000), color-stop(100%, #ffffff)); background: -webkit-linear-gradient(top, #000000 0%, #ffffff 100%); background: -o-linear-gradient(top, #000000 0%, #ffffff 100%); background: -ms-linear-gradient(top, #000000 0%, #ffffff 100%); background: linear-gradient(to bottom, #000000 0%, #ffffff 100%); } </style> </head> <body> <div> </div> </body> </html>
chrome浏览器效果:
IE8浏览器效果(无渐变):
.parent { width: 400px; height: 400px; margin: 100px; font-size: 20px; color: #FF0000; border: 1px solid red; background: #000000; background: -moz-linear-gradient(top, #000000 0%, #ffffff 100%); background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #000000), color-stop(100%, #ffffff)); background: -webkit-linear-gradient(top, #000000 0%, #ffffff 100%); background: -o-linear-gradient(top, #000000 0%, #ffffff 100%); background: -ms-linear-gradient(top, #000000 0%, #ffffff 100%); background: linear-gradient(to bottom, #000000 0%, #ffffff 100%); /*关键属性设置*/ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#000000', endColorstr='#ffffff', GradientType=0); }
设置filter属性目的是上一行的透明度不起作用的时候执行,filter: progid:DXImageTransform.Microsoft.gradient是用来做渐变的,GradientType:可读写,设置或检索色彩渐变的方向:
1:默认值。水平渐变。
0:垂直渐变。
