问题
This is working in Chrome but not in Safari:
background: -webkit-radial-gradient(center, ellipse cover, #fdfdfd, #d3d3d3);
How can I fix it for Safari?
回答1:
Try using for Safari:
background: -webkit-gradient( radial, <point>, <radius>, <point>, <radius>[, <stop>]* ) <color>;

It doesn't even work correctly in Chrome, as it shows a circular gradient, not an elliptical one. It does work correctly in Webkit nightlies.
The reason it doesn't work in Safari is that the syntax hasn't propagated yet to a stable version of Safari. Eventually it will. You need to learn patience my young padawan :)
For now, you may use -webkit-gradient, but always include the -webkit-radial-gradient equivalent after it. And while we're at it, don't forget the other prefixes too (-o-,-moz-,-ms-)
