css :target_html/css_WEB-ITnose

Spent half an hour looking for the problem of how to complete: target

Requirement: When you click Main, it will be triggered :target effect

The result was not found on the Internet because I didn’t know what keywords I was looking for, but I finally remembered it. . .

Main

It’s that simple! Simple things are easy to forget~

Principle: When you click a, the url will have the path of #Main. This is the id "Main" in the html and will be triggered once. Please remember it~
