Mobile-side development:
First, the device is broadly divided into 4 types: Mobile: <768px
ipad side: 769-991px
PC side: 992-1200px
Oversized screen: >1200px

Responsive layouts: The concept proposed by Ethan Marcotte in May 2010 means that a Web site can be compatible with multiple terminals rather than
Make a specific version for each terminal. This concept was created to address mobile internet browsing.
Advantages: High flexibility in the face of different resolution devices
Can quickly solve multi-device display adaptation problems
Cons: Compatible with a variety of equipment workload, low efficiency
Code is cumbersome, there will be hidden useless elements, loading time extended
In fact, this is a compromise of the design of the solution, many factors affect the best results
To a certain extent, change the original layout structure of the site, there will be user confusion situation
Usage: @media
Example: Mobile phone-side @media screen and (max-width:767px) {}
Flat End @media screen and (min-width:769px) and (max-width:999px) {}
PC-side @media screen and (min-width:1000px) {}
Recommendation: Width setting 100% Adaptive, Web page head, tail height pattern are unchanged, the rest of the adaptive.

Here's a small example:

<! DOCTYPE html>
<meta charset= "UTF-8" >
<meta name= "viewport" content= "Width=device-width, initial-scale=1.0, maximum-scale=1.0, User-scalable=no" >
<title>Title</title>

<!--<link rel= "stylesheet" href= "./css/pc.css" >-->
<!--<link rel= "stylesheet" href= "./css/app.css" >-->
<!--<link rel= "stylesheet" href= "./css/flat. CSS >-->


<style type= "Text/css" >
