JS implements simple code for responsiveness
1. CSS implementation of responsiveness
CSSThe implementation of responsiveness mainly relies on CSSMedia query:
A media query consists of an optional media type and zero or more expressions to limit the scope of the style sheet using media attributes ,For example: width, height, color. Media queries in CSS3 allow content to be rendered only for a specific range of output devices without having to change the content itself. That is, determine the screen width through media queries and load different CSS style sheets
The code is as follows: Note that there must be a default style sheet without media queries , otherwise there will be no style sheet when accessed in IE8.
<head> <meta charset="UTF-8"> <title>响应式的演示</title> <link rel="stylesheet" type="text/css" href="css/reset.css" /> <link rel="stylesheet" type="text/css" href="css/index1200.css" /> <link rel="stylesheet" type="text/css" href="css/index980.css" media="screen and (min-width:980px) and (max-width:1200px)"/> <link rel="stylesheet" type="text/css" href="css/index640.css" media="screen and (min-width:640px) and (max-width:980px)"/> <link rel="stylesheet" type="text/css" href="css/index320.css" media="screen and (max-width:640px)"/> </head

setCSS();
window.onresize = setCSS;

if(windowWidth >= 1200){
rwdlink.href = "";
}else if(windowWidth >= 980){
rwdlink.href = "css/index980.css";
}else if(windowWidth >= 640){
