CSS:我的父容器的尺寸为0px 0px,如何将其自动设置为子容器的尺寸?

我有一个css元素#main由于某种原因设置为0px x 0px(它工作得更早,我不确定会发生什么变化。)当#main ul为800px x 39px时,因此隐藏整个元素

有没有办法让#main的维度自动更改而无需对其进行硬编码?

我试过了:

overflow: hidden, auto
float: left, center, right
width: 100%
display: block, inline-block, inline

但它们都不起作用。

这里是css代码:

/* HEADERS*/

    margin-top: 80px;
    text-align: center;

我刚刚意识到#main元素在Windows Chrome上实际可见,但在Mac Chrome或Safari(我一直在使用)上却没有,同时仍然具有0px x 0px尺寸。

你可以使用flex。这是设置宽度,边距,填充物的简单方法。

这是一个精彩的"完整指南,适用于flexbox": http://css-tricks.com/snippets/css/a-guide-to-flexbox/

你可以这样做:



nav {
  display: flex;
  flex: 1;
  /* you can set some width if you want
  width: 400px;
  */
  
  background-color: #eee;
}

nav ul {
  margin: 0;
  padding: 0;
  display: flex;
  flex: 1;
  
  list-style-type: none;
  
  background-color: #ddd;
  border: 1px solid #00f;
}

nav ul li {
  display: flex;
  flex: 1;
  padding: 5px 10px;
  margin-right: 10px;
  
  background-color: #bbb;
  border: 1px solid #f00;
}

nav ul li:last-child {
  margin-right: 0;
}

<nav>
  <ul>
    <li>aaaa</li>
    <li>bbbb</li>
    <li>cccc</li>
    <li>dddd</li>
    <li>eeee</li>
  </ul>  
</nav>

您可以将导航的宽度更改为您喜欢的任何内容,或者根本不设置导航的宽度并给导航flex:1为&#34; 100%&#34;。
