【问题描述】:
这就是我的意思,来自 link的代码
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
* {
box-sizing: border-box;
}
.row {
display: flex;
}
/* Create three equal columns that sits next to each other */
.column {
flex: 33.33%;
padding: 5px;
}
</style>
</head>
<body>
<h2>Images Side by Side</h2>
<p>How to create side-by-side images with CSS Flexbox:</p>
<div class="row">
<div class="column">
<img src="img_snow.jpg" alt="Snow" style="width:100%">
</div>
<div class="column">
<img src="img_forest.jpg" alt="Forest" style="width:100%">
</div>
<div class="column">
<img src="img_mountains.jpg" alt="Mountains" style="width:100%">
</div>
</div>
</body>
</html>
使用该代码,有一排并排显示三个图像,如果调整屏幕大小,这三个图像会相应地按比例变大/变小。
我从互联网上找到了有关 amp-html 的类似内容:
<!doctype html>
<html ⚡>
<head>
<meta charset="utf-8">
<title>AMP #0</title>
<link rel="canonical" href="amps.html" >
<meta name="viewport" content="width=device-width,minimum-scale=1">
<style amp-boilerplate>body{-webkit-animation:-amp-start 8s steps(1,end) 0s 1 normal both;-moz-animation:-amp-start 8s steps(1,end) 0s 1 normal both;-ms-animation:-amp-start 8s steps(1,end) 0s 1 normal both;animation:-amp-start 8s steps(1,end) 0s 1 normal both}@-webkit-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-moz-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-ms-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-o-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}</style><noscript><style amp-boilerplate>body{-webkit-animation:none;-moz-animation:none;-ms-animation:none;animation:none}</style></noscript>
<style amp-custom>
.container {
display: flex;
flex-direction: row;
width: 450px;
height: 200px;
margin:auto;
}
</style>
<script async src="https://cdn.ampproject.org/v0.js"></script>
</head>
<body>
<div class="container">
<amp-img class="child-flex-default" src="https://lh3.googleusercontent.com/pSECrJ82R7-AqeBCOEPGPM9iG9OEIQ_QXcbubWIOdkY=w400-h300-no-n" layout=flex-item></amp-img>
<amp-img class="child-flex-default" src="https://lh3.googleusercontent.com/5rcQ32ml8E5ONp9f9-Rf78IofLb9QjS5_0mqsY1zEFc=w400-h300-no-n" layout=flex-item></amp-img>
<amp-img class="child-flex-default" src="https://lh3.googleusercontent.com/Z4gtm5Bkxyv21Z2PtbTf95Clb9AE4VTR6olbBKYrenM=w400-h300-no-n" layout=flex-item></amp-img>
</div>
</body>
</html>
但是 amp-html 代码中的那个在我调整屏幕大小时不会使这三个图像变大/缩小。
所以我试着像这样改变风格:
<style amp-custom>
.container {
display: flex;
flex-direction: row;
max-width: 450px;
height: 200px;
margin:auto;
}
</style>
当我调整屏幕大小时,这三个图像的宽度确实增加/缩小,但高度没有。所以我尝试将height: 200px; 更改为max-height: 200px;,然后所有三个图像都消失了(没有显示)。如果我删除了那个样式中的 height 属性,结果一样,没有显示。
我的问题:
如何编写代码以在调整屏幕大小时使宽度和高度成比例?
