[英]Div 50% inside a container
Can we somehow set up height:50%
for a div that is situated inside a container (preferebly a table cell)? 我们能否以某种方式为位于容器(最好是表格单元)内的div设置
height:50%
?
The dimensions of which we do not know and they may change a lot dynamically. 我们不知道其尺寸,并且它们可能会动态变化很多。
You can set up height for a div however parent elements must have their height set explicitly also. 您可以为div设置高度,但是父元素的高度也必须明确设置。 For example:
例如:
<html>
<head>
</head>
<body style="height:100%">
<table style="height:100%">
<tr>
<td style="height:100%">
<div style="height:50%">
</div>
</td>
</tr>
</table>
</body>
</html>
So doesn't matter that container height changes dynamically, so long as it is set. 因此,只要设置了容器高度,容器高度就不会动态变化。 There's other methods, this is probably the simplest.
还有其他方法,这可能是最简单的方法。
