如果扩展的中心组件的内容超出其边界,则下面的示例包括滚动行为。此外,中心组件在视口中占据剩余空间的100%。
在这里查看 jsfiddle
html, body, .r_flex_container{
height: 100%;
display: flex;
flex-direction: column;
background: red;
margin: 0;
}
.r_flex_container {
display:flex;
flex-flow: column nowrap;
background-color:blue;
}
.r_flex_fixed_child {
flex:none;
background-color:black;
color:white;
}
.r_flex_expand_child {
flex:auto;
background-color:yellow;
overflow-y:scroll;
}
可用于演示此行为的HTML示例
<html>
<body>
<div class="r_flex_container">
<div class="r_flex_fixed_child">
<p> This is the fixed 'header' child of the flex container </p>
</div>
<div class="r_flex_expand_child">
<article>this child container expands to use all of the space given to it - but could be shared with other expanding childs in which case they would get equal space after the fixed container space is allocated.
