我想制作这个UI,每个都是div。标题高度为30px。页脚是30px。但我不知道内容的高度。我需要使用用户框来计算。
总高度应为100%。
我可以在纯CSS中完成吗?
答案 0 :(得分:30)
使用flexbox,很容易实现。
将包含3个分区的包装器设置为display: flex;
,并将其设置为100%
或100vh
的高度。包装器的高度将填充整个高度,display: flex;
将导致具有适当的flex属性(例如flex:1;
)的此包装器的所有子项都使用flexbox-magic进行控制。
示例标记:
<div class="wrapper">
<header>I'm a 30px tall header</header>
<main>I'm the main-content filling the void!</main>
<footer>I'm a 30px tall footer</footer>
</div>
随之而来的CSS:
.wrapper {
height: 100vh;
display: flex;
/* Direction of the items, can be row or column */
flex-direction: column;
}
header,
footer {
height: 30px;
}
main {
flex: 1;
}

在摆弄了一段时间后,我找到了一个适用于&gt; IE7,Chrome,Firefox的解决方案:
* {
margin:0;
padding:0;
}
html, body {
height:100%;
}
#wrap {
min-height:100%;
}
#header {
background: red;
}
#content {
padding-bottom: 50px;
}
#footer {
height:50px;
margin-top:-50px;
background: green;
}
HTML:
<div id="wrap">
<div id="header">header</div>
<div id="content">Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim.
