在下面给定的布局中，
当页面宽度低于 600px 时，我想将 Column2 放在 Column1 之上
我尝试使用 display: flex; flex-direction: column-reverse; 但它不是颠倒列的顺序，而是颠倒列的内容顺序。
这是片段。
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
* {
box-sizing: border-box;
}
/* Create two equal columns that floats next to each other */
.column {
float: left;
width: 50%;
padding: 10px;
height: 300px; /* Should be removed. Only for demonstration */
}
/* Clear floats after the columns */
.row:after {
content: "";
display: table;
clear: both;
}
/* Responsive layout - makes the two columns stack on top of each other instead of next to each other */
@media screen and (max-width: 600px) {
.column {
width: 100%;
/**Uncommenting below will lead to content of column reversed and not the order of column reversed**/
/*display: flex;
flex-direction: column-reverse;*/
}
}
</style>
</head>
<body>
<h2>Responsive Two Column Layout</h2>
<p>Resize the browser window to see the responsive effect (the columns will stack on top of each other instead of floating next to each other, when the screen is less than 600px wide).</p>
<div class="row" style="height: 20px; background-color: red;">
</div>
<div class="row" style="height: 20px; background-color: blue;">
</div>
<div class="row">
<div class="column" style="background-color:#aaa;">
<div class="cls1">
<h2>Column 1</h2>
<p>Some text..</p>
</div>
<div class="cls2">
<h2>Column 1.2</h2>
<p>Some text..</p>
</div>
<div class="cls3">
<h2>Column 1.3</h2>
<p>Some text..</p>
</div>
</div>
<div class="column" style="background-color:#bbb;">
<h2>Column 2</h2>
<p>Some text..</p>
</div>
</div>
</body>
</html>我们将不胜感激。
最佳答案
您尝试将 display:flex 添加到该列 - 这使该列成为一个 flex 容器 并且其中的元素成为他的 flex 元素。这就是为什么要反转列内的内容而不是列本身。您想要控制行内的列。为此，您需要将该行设为您的 flex 容器(将 display:flex 应用于行而不是列)。这是适用于您的案例的有效 CSS:
.row {
display: flex; // makes the row a flex container
}
@media screen and (max-width: 600px) {
.row {
flex-direction: column-reverse;
}
}
.column {
flex-grow: 1; // makes all columns fill the width of the row equally
padding: 0 10px;
}
