CSS-float：在div上不離開流程

Question

我有2個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> 

但是類main-cta的div似乎仍然在第二行？ 這是為什么？ 我以為，當您浮動div時，它將從文檔流中彈出，下一個元素將占據浮動元素所在的第一行並被其隱藏？

我有點困惑。

謝謝！

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>

我認為這對您有幫助。

 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*/
}

或者您不喜歡添加float:left ，則可以使用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; 
}

為了使div從流中彈出，您需要使div的position為絕對position 。

float要求div在同一行中left移動。
