CSS-float：在div上不离开流程

Question

我有2个div：

  div.main-info { background: yellow; width: 50%; float: left; } div.main-cta { background: red; width: 20px; } 

  <div id="wrapper"> <div class="main-info"> <h1>Lorem Ipsum?</h1> <p> Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. </p> </div> <div class="main-cta"> <div class="window-cta"> <p>Compare Now!</p> </div> </div> </div> 

但是类main-cta的div似乎仍然在第二行？ 这是为什么？ 我以为，当您浮动div时，它将从文档流中弹出，下一个元素将占据浮动元素所在的第一行并被其隐藏？

我有点困惑。

谢谢！

Try this

<style>
div.main-info {
    background: yellow;
    width: 50%;
    float: left;
}

div.main-cta {
    background: red none repeat scroll 0 0;
    float: left;
    width: auto;
}

</style>

我认为这对您有帮助。

 div.main-info { background: yellow; width: 50%; float: left; } div.main-cta { background: red; background: red none repeat scroll 0 0; float:right; }

只需在div.main-cta添加float:left即可。

div.main-info {
    background: yellow;
    width: 50%;
    float: left;
}
div.main-cta {
    background: red;
    width: 20px;
    float: left; /*new line*/
}

或者您不喜欢添加float:left ，则可以使用display:inline-block;

div.main-info {
    background: yellow;
    width: 50%;
    display: inline-block; /*new line*/
}
div.main-cta {
    background: red;
    width: 20px;
    display: inline-block; /*new line*/
    vertical-align: top; 
}

Answer 4

为了使div从流中弹出，您需要使div的position为绝对position 。

float要求div在同一行中left移动。
