CSS background-size not working in IE7/8
提问by Nealv
For some reason my background size is not working in IE 7&8. Can anyone tell me why. Also in the IE inspector, the background-size property is not showing up.
出于某种原因，我的背景大小在 IE 7&8 中不起作用。谁能告诉我为什么。同样在 IE 检查器中，background-size 属性没有显示。
<a href="" class="twitter-custom-follow-button"></a>
.twitter-custom-follow-button {
float: left;
width: 96px;
height: 20px;
background: url(../img/slices/btns/twitter_follow.png);
background-size: 96px 20px;
background-repeat: no-repeat;
}

That's because background-sizeis a CSS3 property which isn't supportedbefore IE9.
这是因为IE9 之前不支持background-sizeCSS3 属性。
However, there is a thread which suggests a possible workaround: How do I make background-size work in IE?
但是，有一个线程提出了一种可能的解决方法： 如何在 IE 中使背景大小工作？

IE 7/8 doesn't support the background-sizeproperty .. you will need to use javascript if you want the same functionality
IE 7/8 不支持该background-size属性.. 如果您想要相同的功能，您将需要使用 javascript

IE7/8 do not support background-size. It was only introduced in IE9.
IE7/8 不支持background-size。它仅在 IE9 中引入。
If you want to support IE7/8 with this property, you'll need to use a polyfill script for it.
如果你想用这个属性支持 IE7/8，你需要为它使用一个 polyfill 脚本。
The only polyfill I know of that supports background-sizeis CSS3Piev2. Give it a go. (it also adds support for several other CSS features that aren't in old IE versions)
我所知道的唯一支持background-size的polyfill是CSS3Piev2。搏一搏。（它还增加了对旧 IE 版本中没有的其他几个 CSS 功能的支持）
