问题描述

我有一个 DIV （设置为 float：left ），其宽度

在 上，我想增加 width

当在中设置固定的宽度 ：hover CSS类，容器将在悬停时获取 width ，但

1. CSS3-


2. 如果我的 DIV 的内容大于固定的 width em>，最后的宽度将不正确。

我保持 DIV 的内容已调整到其内容，并将它的宽度增加一定量的像素悬停？

解决方案

我看到你的小提琴，虽然我不知道这是你需要的确切效果，请尝试：

  .myDiv：hover {
 padding-right：20px; 
} 
  

I have a DIV (that is set to float:left) that has its width set to auto because i want it to be just as wide as its contents.

On hover, i would like to increase width of the DIV by say, 20 pixels.

When setting a fixed width in the :hover CSS class, the container will get that width on hover, but

1. CSS3-Transitions won't apply/work (tested in Firefox 15.0.1)
2. If my DIV's contents are larger than that fixed width, the final width will not be correct.

How - without the usage of javascript - can i keep the content of the DIV adjusted to its content, and have it increase that width by a certain amount of pixels on hover?

See my JSFiddle here.

解决方案

I saw your fiddle, though I'm not sure this is the exact effect you need, try this:

.myDiv:hover {
    padding-right: 20px; 
}
