Causes and solutions to garbled CSS comments

CSS comments are a very important part of CSS style sheets, which can make it easier for developers to read and maintain code, and can also provide specific information and guidance to others. However, sometimes we encounter CSS comments that are garbled, which makes it very difficult to read and maintain the code. This article will introduce the causes and solutions of garbled CSS comments.

1. Syntax of CSS comments

In CSS style sheets, we can use two methods of comments. The first is a single-line comment, use the "//" symbol to comment:

/* 这是单行注释 */

The second is a multi-line comment, use the "/ ... /" symbol to comment:

/* 这是
多行注释 
*/

Comments can appear anywhere in a CSS file and will not affect CSS style rules. The purpose of comments is to provide more information and explanations to the code so that developers can better understand the code.

2. Reasons why CSS comments are garbled

There are many reasons why CSS comments are garbled. Here are some common situations:

1. Character set mismatch: If the CSS file uses a different character set encoding than the HTML file, the comments will be garbled.
2. Editor setting problem: Some editors will automatically insert special characters (such as BOM) into the code, causing comments to be garbled.
3. Using an incompatible character set: Using some incompatible characters (such as Chinese characters) in CSS comments will also cause the comments to be garbled.
4. Incorrect comment syntax is used: If incorrect comment syntax is used, and the comment is not closed properly, it may also cause the comment to be garbled.

3. Methods to solve the problem of garbled CSS comments

1. Check the character set: Please ensure that the CSS style sheet and HTML file use the same character set encoding. It is recommended to use UTF- 8 encoding.
2. Choose the right editor: Use an editor that does not insert special characters (such as BOM) into the code.
3. Avoid using incompatible characters: Try to avoid using incompatible characters, such as Chinese characters, in comments.
4. Use correct comment syntax: Please pay attention to the syntax of comments to ensure that comments can be closed correctly.

For example:

/* 正确的多行注释语法 */ 
/* 
这是一个
多行注释 
*/
 
/* 正确的单行注释语法 */
/* 这是单行注释 */

5. Transcoding: If you have written CSS code and find that the comments are garbled, you can try to convert the code to UTF-8 encoding and ensure that the file There is no BOM character in the header.
