子div是否继承父母的身高？

时间：2019-05-31 00:58:03

标签： css inheritance

据我所知，孩子div通常继承父母的风格。但是，我的CSS并非如此，因此我无法控制子高度。对此工作的任何澄清将不胜感激

我曾尝试过切换到position:relative和display:inline，但是还没有找到任何能改变子div高度的东西。

// Plot our graphs
var data = [
  {
    z: [[1, 20, 30], [20, 1, 60], [30, 60, 1]],
    type: 'heatmap'
  }
];

Plotly.newPlot('chart_div', data);

子元素不继承其父元素的高度。

MDN

Reference: MDN

不过，您可以将其值设置为@square_array = Hash.new # or @square_array = {} CodePen Example

您还可以使用height:inherit;或height: 100%

在任何情况下，如果内容太大而不能满足该设置高度，则必须考虑要做什么：max-height: 100%; overflow: hidden; overflow-y:hidden。
