css3media responsive layout example analysis
Responsive layout can provide a more comfortable interface and better user experience for users on different terminals. With the current popularity of large-screen mobile devices, it is not an exaggeration to describe it as "the general trend". As more and more designers adopt this technology, we are not only seeing a lot of innovation, but also seeing some established patterns. With the development of technology, the characteristics of CSS3 have also been widely used. Many of its new tags are also very easy to use and easy to learn. Just like the responsive layout of CSS3, it is also very powerful. Web pages that were originally only displayed on the PC Now you can make a web page responsive by adding @media. It can be used on PC or mobile and can be really scalable. For example,
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<style>
/* 小于200px*/
@media only screen and (max-width:200px ) {
#p{
background: red;
}
}
/* 大于300px*/
@media only screen and (min-width:300px ) {
#p{
background: yellow;
}
}
</style>
<body>
<p id="p">小于200px背景变红色大于300px背景为黄色</p>
</body>
</html>this The effect of the code segment 
@media can be used for single conditions or double conditions. For example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<style>
/* 小于200px*/
@media (min-width:200px ) and (max-width:500px ) {
#p{
background: red;
}
}
</style>
<body>
<p id="p">200px以上并且500px以下背景变成红色</p>
</body>
</html>This code is less than 200px or If the size is larger than 500px, the effect will not be displayed.
A simple @media can realize the responsive page. Isn’t it very easy?
A page I made casually. This is the page effect above 450px
This is the page effect below 450px
The general approach is to responsively shrink each p block to below 450px. When the width of each p is 100%
The height is auto. I encountered a small problem when I was writing this web page. When I reached the bottom of the page, the bottom navigation flew away. It did not fall peacefully at the bottom but in the middle. I will share a little knowledge here. That's my final solution. I just need to give the p at the bottom a style clear: both, so that the bottom will be securely fixed to the bottom. In the media, there will also be responsive styles for horizontal and vertical screens, and vertical screens. For @media (orientation:portrait)
vertical screen is @media (orientation:landscape) so that it can adapt to horizontal and vertical screens. Media has many advantages, such as when we create our own resume. If we can use responsive layout, our chances will be much greater. HR may also see your resume on the mobile phone. At this time, opportunities may quietly come to you.
