First of all, let’s learn about the use of a tag:

html The most important attribute in the a tag is the href attribute, and it is also a necessary attribute of the a tag, because the href attribute What is defined is the target of the link. (For more introduction, please visit "PHP Chinese website")

The appearance of the link defined by the a tag is the same in all browsers, with a total of three colors

Now there are also cascading style sheet files or the addition of javascript files, making the tag more diverse. Let’s talk about this later.
