CSS (Cascading Style Sheets) is a style sheet language commonly used in web design. It can control the style of web pages, including fonts, colors, sizes, layouts, etc., making web pages more readable and beautiful. . To use CSS, you need to introduce the CSS file into the HTML file. Three methods of introducing CSS will be introduced below.

1. Inline style

Inline style is a method of writing CSS styles directly inside HTML element tags. The advantage of this approach is that it can be styled on a single HTML element, but it can become very verbose and repetitive if you want to apply the same style on multiple elements. The syntax of inline style is as follows: 

<p style="color: red;">这是红色文本</p>

Among them, the style attribute is used to define the style. The style attribute and value are separated by colons, and multiple attributes are separated by semicolons.

2. Internal style sheet

The internal style sheet is to write the CSS style in the c9ccee2e6ea535a969eb3f532ad9fe89# of the 93f0f5c25f18dab9d176bd4f6de5d30e tag of the HTML file. ## Inside the tag. This method is suitable for situations where multiple elements within an HTML file share styles. The syntax of the internal style sheet is as follows: 

<!DOCTYPE html>
<html>
    <head>
        <style>
            p {
                color: red;
            }
        </style>
    </head>
    <body>
        <p>这是红色文本</p>
    </body>
</html>

Among them,

c9ccee2e6ea535a969eb3f532ad9fe89 writes the CSS style inside the tag. The style is similar to the inline style, but does not need to be written inside the element tag. Instead Written in the middle of { }, multiple attributes and values ​​are also separated by semicolons.

3. External style sheet

The external style sheet is to write the CSS style separately in a

.css file, and then use the tag to introduce it. This method is suitable for situations where multiple HTML files need to share the same style. The syntax of an external style sheet is as follows:

    Create a
  1. .css file, such as style.css.
    2. Write the CSS style to be introduced, for example: 
  2. p {
  color: red;
}
    Add the following code to the
  1. 93f0f5c25f18dab9d176bd4f6de5d30e tag in the HTML file: 
    2. <!DOCTYPE html>
<html>
  <head>
    <link rel="stylesheet" href="style.css">
  </head>
  <body>
    <p>这是红色文本</p>
  </body>
</html>
Among them, the

2cdf5bf648cf2f33323966d7f58a7f3f tag is used to specify the path of the .css file, and the href attribute is used to specify.css The path and file name of the file.

The above are the three methods of introducing CSS. Each method has its own applicable scenarios and can be selected and used according to specific needs.
