css - 我缺少什么渐变？

Question

csslint.net 给我这个错误:

Missing vendor-prefixed CSS gradients for Old Webkit (Safari 4+, Chrome), Opera 11.1+.

.ui-dialog, .grey_box {
  background:  -moz-linear-gradient(top, #fefefe, #dddddd);
  background:  -webkit-linear-gradient(top, #fefefe, #dddddd);
  background:  -ms-linear-gradient(top, #fefefe, #dddddd);
}

Answer 1

你需要添加这两个额外的

.ui-dialog, .grey_box {
  background:  -webkit-gradient(top, #fefefe, #dddddd);
  background:  -o-linear-gradient(top, #fefefe, #dddddd);
  background:  -moz-linear-gradient(top, #fefefe, #dddddd);
  background:  -webkit-linear-gradient(top, #fefefe, #dddddd);
  background:  -ms-linear-gradient(top, #fefefe, #dddddd);
}
