What are CSS comment symbols?

In CSS style sheets, comments are text fragments that are used to provide explanations for the code but do not affect the actual functionality of the code. CSS comments are usually used to record the purpose, author, last modification time, code function and other information of CSS style sheets.

The syntax of CSS comment symbols

CSS comments use symbols starting with / and ending with /, with the content of the comment included in the middle, as follows:

/ This is a CSS comment /

Comments can contain any text, including HTML or any other code. Comments can be written on the same line or within multiple lines, as shown below:

/* This is
an example of a multi-line comment
*/

Single-line comment
/ This is a single-line comment style /

Multi-line comment
/* This is
an example of a multi-line comment style
*/
