Bellow 是我正在使用的 CSS。带有 largebutton 类的 div 可以工作，悬停除外。我希望它改变它的背景颜色，但我不确定为什么它不起作用。有什么想法吗？
编辑 - 我目前在 FF 工作。我不寻求 IE6 的支持，可能也不是 IE7。
.top .bottombar .largebutton
{
position: relative;
float: left;
height: 100%;
width: 195px;
font-size: 13px;
letter-spacing: 1px;
text-transform:uppercase;
line-height: 33px;
text-align: right;
background-color: #99CCFF;
margin-left: 5px;
padding-right: 5px;
overflow: hidden;
cursor: pointer;
}
.top .bottombar .largebutton:hover
{
background-color: #9999FF;
}

我认为这是 Firefox 中的错误。有时，当您为嵌套类添加 CSS 而没有指定这些应用到哪些元素时，浏览器会变得疯狂。您的代码在其他浏览器中工作正常，所以从技术上讲这不是您的错，而是 FF 的错；)
