Web Front-endHTML TutorialHow HTML web pages automatically adapt to mobile phone screens_html/css_WEB-ITnose
I saw the following method on the Internet:
However, some mobile phones can automatically adapt to the screen size, while others cannot. Why? (Is it related to the screen resolution of the mobile phone?)
In addition, adding this code will cause problems with the spacing between the buttons on the left side of the webpage and the table on the right side. There is a gap when the screen is horizontal, but when the screen is vertical, there is a gap. This will cause the buttons and tables to overlap. Why is this?

It is still difficult to control simply through js. If it is not complicated, just write two versions, or use % to control the height and width of your css (this It’s more difficult than writing two versions)

@media screen and (max-width: 480px){
.aa{ width:60px; height:60px;}

The frame is a good thing
Just patch the width
