IE7宽度:自动发布

Question

CSS

    #wrapper .tn{
      width:auto;
      height:20px;
      line-height:20px;
      float:left;
      padding:5px 2px 5px 5px;
      margin:0 5px 10px;
      font-weight:bold;
      background:#f0f0f0;
    }

HTML

    <div id="wrapper">
        <div class="tn">Text</div>
        <div class="tn">Text</div>
        <div class="tn">Text</div>
    </div>

上面的代码在FF，Chrome，Safari，Opera，IE9，IE8中运行流畅。但对于IE7来说，这是个问题。Div不会根据text.It cover wrapper div的宽度展开。我该如何解决这个问题呢？

Answer 1

在我看来很好，使用IE7开发人员工具检查，您可以尝试display: inline-block;而不是float

#wrapper .tn{
  height:20px;
  line-height:20px;
  padding:5px 2px 5px 5px;
  margin:0 5px 10px;
  font-weight:bold;
  background:#f0f0f0;
  display: inline-block;
}

Answer 2

我假设您所说的div是#wrapper？#wrapper不会扩展，因为您需要清除浮动

查看HTML5样板文件(https://github.com/h5bp/html5-boilerplate/blob/master/css/main.css)中的clearfix类

.clearfix:before,
.clearfix:after {
    content: " "; /* 1 */
    display: table; /* 2 */
}

.clearfix:after {
    clear: both;
}

/*
 * For IE 6/7 only
 * Include this rule to trigger hasLayout and contain floats.
 */

.clearfix {
    *zoom: 1;
}

所以在你的代码中这样做：

<div id="wrapper" class="clearfix">
    <div class="tn">Text</div>
    <div class="tn">Text</div>
    <div class="tn">Text</div>
</div>
