通过CSS根据另一个div调整div的高度 [英] adjust a div's height based on another div by CSS
问题描述
我有两个DIV(一个是侧边栏,另一个是内容部分),我需要具有相同的高度,但是我遇到了问题.侧边栏包含一些li
.我希望边栏的高度与内容部分的高度相同,但是当我使用flex
时,边栏的高度可以比内容部分长(因为这两个部分都是动态的).因此,我需要在高度大于内容部分时滚动边栏.
I have two DIVs (one is a sidebar and the other one is a content part) that I need to have the same height but I have a problem. The sidebar includes some li
s. I want the height of the sidebar to be the same as the content part but when I use flex
, the height of the sidebar can be longer than the content part (because both parts are dynamic). So I need the sidebar to be scrolled when the height is longer than the content part.
<section class="container">
<div class="sidebar">
<ul>
<li><li>
<li><li>
<li><li>
<li><li>
<li><li>
</ul>
</div>
<div class="content"></div>
</section>
我的CSS代码:
.container {
display: flex;
}
.sidebar,.content {
flex: 1 0 auto;
}
我什至使用了JQuery,但是我们看到错误的高度,因为图像在内容部分中的加载速度很慢.
I even used JQuery but we see the wrong height because images are being loaded slowly in the content part.
我的JQuery代码:
My JQuery code:
jQuery(document).ready(function($) {
$(".sidebar").height($(".content").height());
});
我什至使用了以下代码,但没有任何反应:
I even used the following code but nothing happens:
jQuery( window ).load(function($) {
$(".sidebar").height($(".content").height());
});
我不想使用position:absolute
,因为...您可以在此链接中看到我的页面:
I do not want to use position:absolute
because... You can see my page in this link: https://end-eng.com/landing-grammar/
推荐答案
我希望在边栏长于内容时滚动边栏.所以我用纯CSS解决了它:
我的新HTML代码:
as I told above, I wanted sidebar to be scrolled when the sidebar is longer than content. so I solved it by pure CSS:
my new HTML code:
<section class="container">
<div class="sidebar">
<div class="sidebardiv">
<ul>
<li><li>
<li><li>
<li><li>
<li><li>
<li><li>
</ul>
</div>
</div>
<div class="content"></div>
</section>
我的新CSS代码:
.container {
display: flex;
}
.sidebar , .content {
flex: 1 0 auto;
}
.sidebardiv {
position: absolute;
top: 0;
right: 0;
height: 100%;
overflow: auto;
padding: 0 8px 0 8px;
}
