Center single- AND multi-line li text vertically

csslistcenter

提问by Raphael Müller

I have an unordered list with a background-image set. All list-items have the same height, the background-image is positioned left center.

我有一个带有背景图像集的无序列表。所有列表项具有相同的高度,背景图像位于左中心。

The text of each item should be centered verticallyto the li. This works well with single-line text (by setting the line-height according to the height of the li), but not with two lines of text.

每个项目的文本应与 li垂直居中。这适用于单行文本(通过根据 li 的高度设置 line-height),但不适用于两行 text

I could add "line-height:normal" to the two-line item, but I want a solution that works for all items.

我可以在两行项目中添加“line-height:normal”,但我想要一个适用于所有项目的解决方案。

How can I do this?

我怎样才能做到这一点?

Example:

例子:

li { 
    list-style-type:none; 
    padding-left:40px; 
    height:36px;
    line-height:36px; 
    background:url('tick.png') no-repeat 0 50%; 
}

this is a most crossbrowser solution

这是一个最跨浏览器的解决方案

    li {
     width           : 200px;
        line-height     : 100px;
        height          : 100px;
     border          : 1px blue solid;        
    }
    li span {
     display    : -moz-inline-box;  /* FF2 or lower */
     display    : inline-block;     /* FF3, Opera, Safari */
        line-height         : normal;
        vertical-align      : middle;    
    }
    
    li span  { *display : inline;} /* haslayout for IE6/7 */
<ul>
       <li><span>My text</span></li>
       <li><span>My longer text</span></li>
       <li><span>My text, but this time is really wide</span></li>
       <li><span>My text, some thoughts about how much it will expand in this item.</span></li>
    </ul>

I used star hack for brevity, you should avoid. Just use html5boilerplate solution, it uses conditional comments on body tag

为简洁起见,我使用了 star hack,你应该避免。只需使用 html5boilerplate 解决方案,它在 body 标签上使用条件注释
