我的问题是，我正在建立一个网站，使用大量的图像图标，必须由不同的图像悬停交换(例如，蓝色的图像变成红色的悬停)。 对此，我提出了以下解决方案:

.container div { width: 100px; height: 100px; background-size: 100px 100px; } .container:hover .withoutHover { display: none; } .container .withHover { display: none; } .container:hover .withHover { display: block; } <p>Hover the image to see it switch with the other. Note that I deliberately used inline CSS because I decided it was the easiest and clearest solution for my problem that uses more of these image pairs (with different URL's). </p> <div class=container> <div class=withHover style="background-image: url('https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcQrqRsWFJ3492s0t0NmPEcpTQYTqNnH188R606cLOHm8H2pUGlH')"></div> <div class=withoutHover style="background-image: url('http://i.telegraph.co.uk/multimedia/archive/03523/Cat-Photo-Bombs-fa_3523609b.jpg')"></div> </div>

我引入了一个包含这对图像的容器。第一个是可见的，另一个是隐藏的(display:none)。当悬停容器时，第一个容器将被隐藏(display:none)，第二个容器将再次显示(display:block)。

只能在外部样式表中使用伪类a:hover。因此，我建议使用外部样式表。代码是:

a:hover {color:#FF00FF;}   /* Mouse-over link */

你可以在过去的某个时候这样做。但现在(根据同一标准的最新修订，即候选人推荐)你不能这样做了 ．

我只是想出了一个不同的解决方案。

My issue: I have an <a> tag around some slides/main content viewer as well as <a> tags in the footer. I want them to go to the same place in IE, so the whole paragraph would be underlined onHover, even though they're not links: the slide as a whole is a link. IE doesn't know the difference. I also have some actual links in my footer that do need the underline and color change onHover. I thought I would have to put styles inline with the footer tags to make the color change, but advice from above suggests that this is impossible.

解决方案:我给了脚注链接两个不同的类，我的问题就解决了。我能够有onHover的颜色改变在一个类，有幻灯片onHover没有颜色变化/下划线，仍然能够有外部href在页脚和幻灯片在同一时间!

它不是内联CSS，但它是内联的。

<a href=“abc.html” onMouseOver=“this.style.color='#0F0'” onMouseOut=“this.style.color='#00F'”>Text</a>

你可以像这样使用内联样式表语句:

<style>#T1:hover{color:red}</style><span id=T1>Your Text Here</span>
