How to add comments to css

CSS with comments

In daily front-end development, we often use CSS to render web page styles. As the project continues to develop, the complexity of styles also increases, and then we need annotations to help us better manage CSS code.

Why use CSS comments?

CSS comments refer to adding some special syntax to the CSS file to mark the function, meaning, characteristics, etc. of the code. Throughout the CSS style sheet, there are two types of comments: single-line comments and multi-line comments. The purpose of comments is to facilitate code reading and maintenance, and to improve code readability and maintainability during team collaboration. CSS comments can record the following aspects:

1. Form and specifications: Comments can remind developers to follow website specifications, standards, and the designer's style.
2. Function and description: Comments can make it easier for developers to understand the specific functions of the code and identify the differences between code blocks.
3. Principles and strategies: Annotations can describe specific strategies, implementation methods, selectors, etc., to help developers understand the composition of code blocks.

CSS comment example:

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

Multi-line comment:
/*
This is a multi-line comment
Code snippet
*/

How to add a CSS comment

Adding comments in CSS is very simple, for single-line comments, We can use "/" and "/" to wrap the comment content. For multi-line comments, you first need to start the comment with the "/" symbol, and then end the comment with the "/" symbol. The following is an example:

Single-line comments:

h1 {
  color: red; /* 这是一个用于表示标题的样式 */ 
}

Multi-line comments:

/* 
这是一个多行注释
用于设置背景颜色
*/
body {
  background-color: #f4f4f4;
}

Summary

During the development process, good comments can make our Code is easier to read, understand, and maintain. At the same time, in team collaboration, comments can improve the readability and maintainability of the code, while also reducing communication barriers between team members. Therefore, when writing CSS code, we should develop a good habit of commenting to facilitate future maintenance and improvement.
