Let's take a look at this article "What are the common class selector types of CSS".

Common class selector types are as follows:

1. label selector, label selector name {css style code;}

2. class selector, class selector name {css style code;}

3. ID selector,#selector name {css style code;}

4. Child selectors, i.e. greater than symbol (>), are used to select first-generation child elements of a given label element.

5. Contains selectors, i.e. spaces, for selecting descendants of a given tag element.

6. Universal selector, matches all tag elements in html, * {css style code;} Both class selector and ID selector can be applied to any element, but ID selector can only be used once in a document, you can use the class selector word list method to set multiple styles for an element at the same time, ID selector is not allowed.

Child selectors differ from include selectors in that> works on the first descendant of an element, and spaces work on all descendants of an element.

There are two other options:

1. Pseudo-class selectors allow styling tags that do not exist in HTML (a certain state of the tag). A:hover{color:red;}

2. Group selector, when setting the same style for multiple tag elements in HTML, you can use group selector,

For example h2,span{color:red;}
