转一个关于safari的css hack。

In March 2007, I wrote about a Safari CSS hackcalled the "Pound Safari Post Semicolon" hack (coined by Tony at Simian Design). As of Safari 3.0, this hack no longer works. However, there is a way to target Safari 3.0 (and Opera as well):
@media screen and (-webkit-min-device-pixel-ratio:0) {
/* Safari 3.0 and Opera 9 rules here */
}
As always, the disclaimer(免责声明): nobody condones the use of hacks, but we all (well, most of us) have to make use of them at least once in a while. The above code targets both Safari 3.0 and Opera 9. Hopefully, it will be a future-proof（未来保证） hack, since the -webkit part of the selector will probably not be adopted by other browsers.
Example: The following code set the background color of the <body> element red in all browsers and then resets it to blue in Safari 3.0 and Opera 9.
body { background-color: red; }
@media screen and (-webkit-min-device-pixel-ratio:0) {
body { background-color: blue; }
}
