怎样通过css的media属性，适配不同分辨率的终端设备，示比例如以下:
<!DOCTYPE html>
<html>
<head>
<title>首页</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="this is my page">
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<style>
@media (max-768px) {
#div1 {
width: 400px;
margin: 0 auto;
background:url('../img/1.JPG');
}
#img2,#img3 {
width: 100px;
}
}
@media (min-768px) {
#div1 {
width: 600px;
margin: 0 auto;
background:url('../img/1.JPG');
}
#img2,#img3 {
width: 200px;
}
}
@media (min-992px) {
#div1 {
width: 800px;
margin: 0 auto;
background:url('../img/1.JPG');
}
#img2,#img3 {
width: 300px;
}
}
@media (min-1200px) {
#div1 {
width: 1000px;
margin: 0 auto;
background:url('../img/1.JPG');
}
#img2,#img3 {
width: 400px;
}
}
</style>
</head>
<body>
<div id="div1">
<img id="img2" alt="img2" src="../img/2.JPG">
<img id="img3" alt="img3" src="../img/3.JPG">
</div>
</body>
</html>当然。也能够依据终端分辨率的变化去引用不同的css文件，示比例如以下:
<!DOCTYPE html>
<html>
<head>
<title>首页</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="this is my page">
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<link rel="stylesheet" media="(max- 768px)" href="../css/max-768px.css">
<link rel="stylesheet" media="(min- 768px)" href="../css/min-768px.css">
<link rel="stylesheet" media="(min- 992px)" href="../css/min-992px.css">
<link rel="stylesheet" media="(min- 1200px)" href="../css/min-1200px.css">
</head>
<body>
<div id="div1">
<img id="img2" alt="img2" src="../img/2.JPG">
<img id="img3" alt="img3" src="../img/3.JPG">
</div>
</body>
</html>注意: 仅仅须要将第一个文件中面的ccs写入四个css文件。
