How to add css style to html

External style sheet:

The external style sheet is an independent CSS file that is referenced in the HTML file through the tag. This is the most recommended method because it keeps style and content separated, improving code maintainability. At the same time, external style sheets can be referenced in multiple HTML files to achieve code reuse.

Suppose we have a CSS file named styles.css with the following content:

p {  
  color: red;  
}

The code to reference the CSS file in the HTML file is as follows:

  
  
  
    

  
  
  
这是一段红色的文本。
  
  

In the above In the code, the href attribute specifies the path to the CSS file. If the CSS file and HTML file are in the same directory, you can use the file name directly. If they are not in the same directory, you need to provide a relative path or an absolute path.

In addition to the above three methods, you can also use the @import statement to reference CSS styles. The @import statement can be used anywhere in an HTML document, but it is usually placed within the tag. When using the @import statement, you need to specify the path of the CSS file to be imported.

Sample code:

  
  
  
    

  
  
  
这是一段红色的文本。
