我们使用 border 属性来创建缩略图。
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>php中文网(php.cn)</title>
<style>
img {
border: 1px solid #ddd;
border-radius: 4px;
padding: 5px;
}
</style>
</head>
<body>
<h2>缩略图</h2>

</html>Response Style pictures
Responsive pictures will automatically adapt to screens of various sizes.
In the example, you can see the effect by resetting the browser size:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
img {
max-width: 100%;
height: auto;
}
</style>
</head>
<body>
<h2>响应式图片</h2>
<p>响应式图片会自动适配各种尺寸的屏幕。</p>
<p>通过重置浏览器大小查看效果:</p>
<img src="http://imgstore.cdn.sogou.com/app/a/100540002/503008.png" alt="Norway" width="1000" height="300">

This example demonstrates how to combine CSS and JavaScript to render pictures together.
First, we use CSS to create a modal window (dialog box), which is hidden by default.
Then, we use JavaScript to display the modal window. When we click on the image, the image will be displayed in the pop-up window
