自动高度div [英] Auto height of div
问题描述
浏览器仅在设置精确高度时显示div。但我想根据它的内容创建可调整大小的div。试用高度：自动和高度：100％。它不会帮助。
Browser shows div only when I set exact height. But i want to create resizable div according it's contents. Tried height: auto and height:100%. It doesn't help.
我的div看起来像这样。它是侧边栏和内容的背景div。
My div looks like that. It's background div of sidebars and content.
.wrapper
{
width: 80%;
height:200px;
max-width: 1260px;
min-width: 780px;
margin: 0 auto;
background-image:url(core/design/img/transfff.png);
-moz-border-radius: 15px 15px 0px 0px;
border-radius: 15px 15px 0px 0px;
}

推荐答案
div
div's will naturally resize in accordance with their content.
如果你在div上没有设置高度，它会展开以包含它的内容。
If you set no height on your div, it will expand to contain its conent.
此规则的例外是当div包含浮点元素时。如果是这种情况，你需要做一些额外的工作，以确保包含div（包装器）清除浮动。
An exception to this rule is when the div contains floating elements. If this is the case you'll need to do a bit extra to ensure that the containing div (wrapper) clears the floats.
这里有一些方法： / p>
Here's some ways to do this:
#wrapper{
overflow:hidden;
}
或
#wrapper:after
{
content:".";
display:block;
clear:both;
visibility:hidden;
}
