It only takes two steps to add comments in CSS: use the comment symbols /* or // to enter the comment content between the comment symbols
How to add comments in CSS
The method of adding comments in CSS is very simple. There are two steps:
Step 1: Use the comment symbol
CSS comments can use two comment symbols:
-
/*
and*/
: multi-line comments -
//
: Single line comment
Step 2: Comment content
Enter your comment content between the comment symbols. For multi-line comments, you can write your comment across multiple lines, while for single-line comments, your comment should be completed within a single line.
Example:
Multi-line comments:
/* 这是一个多行注释。 它可以跨多行。 */
Single-line comments:
// 这是一个单行注释。
Comment Type
- Developer Notes: Used to explain code logic or provide other details, for developer use only.
- Browser comments: Used to convey information to the browser, such as fixing specific problems with the browser.
- Documentation comments: Used to generate documentation in CSS files, which can be used by third-party tools.
The Importance of Comments
CSS comments are very important because they can help:
- Enhance the readability of your code and understandability
- Document the complexity of the code
- Provide background information about the purpose and reason of the code
- Facilitate future maintenance and updates
