Need Help About Asterisk Symbol in CSS.

Hello, sorry for bothering you. Anyone say something about Asterisk Symbol [*] in CSS. Why is it used?

 

* selects all elements.

* can also select all elements inside another element, so for example:

div * {
color: red;
}

Will change all elements inside div's color to red.

 

The use of symbols [*] in the css to make choosing the elements of content as quickly as possible
