amp-html中的代码如何响应多列图像?

标签: html css amp-html responsive-images

这就是我的意思,从此 link中获得代码

<!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,一行并排显示三个图像,如果调整屏幕大小,则这三个图像将相应地按比例变大或变小。

我从互联网上发现了有关amp-html的信息:

<!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,当我调整屏幕大小时,amp-html代码中的那一张并不会使这三张图片变大/缩小。

所以我试图改变这种风格:

  <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了/缩小了,但是高度却没有。因此,我尝试将height: 200px;更改为max-height: 200px;,然后将所有三个图像都消失了(不显示)。如果我删除了该样式的height属性,则没有显示结果。

我的问题:
如何编写代码,以便在调整屏幕大小时使宽度和高度成比例地增大?

1 个答案:

答案 0 :(得分:1)

如下更改您的样式:

 .container {
    display: flex;
 }

 .child-flex-default{
    width: 100%; // Or 33.33%, or whatever. Just make sure you specify in %
 }

现在,您必须使用amp-img来更改layout="responsive"标签:

<amp-img width="150" height="200" layout="responsive" class="child-flex-default" src="https://lh3.googleusercontent.com/pSECrJ82R7-AqeBCOEPGPM9iG9OEIQ_QXcbubWIOdkY=w400-h300-no-n"></amp-img>
<amp-img width="150" height="200" layout="responsive" class="child-flex-default" src="https://lh3.googleusercontent.com/5rcQ32ml8E5ONp9f9-Rf78IofLb9QjS5_0mqsY1zEFc=w400-h300-no-n"></amp-img>
<amp-img width="150" height="200" layout="responsive" class="child-flex-default" src="https://lh3.googleusercontent.com/Z4gtm5Bkxyv21Z2PtbTf95Clb9AE4VTR6olbBKYrenM=w400-h300-no-n"></amp-img>

请注意,当您使用响应式布局时,必须指定widthheight属性。现在,您的图像将根据您指定的widthheight的比例进行相应的调整。
