tag pair of the web page to call the external CSS file.

<link rel="stylesheet" type="text/css" href="css文件路径" />

Description of each attribute:

• href attribute sets the address of the external style sheet file, which can be a relative address or Can be an absolute address.

• The rel attribute defines the associated document, which here indicates that the associated document is a style sheet.

• The type attribute defines the type of imported file. Like the style element, text/css indicates a CSS text file.

Note:

Method 2: Loading via @import

Use the @import command to import external style sheet information into the page. It exists in the tags.

<style type="text/css">
@import url("css文件路径");
</style>

Using @import to introduce CSS can easily introduce CSS code from external files, making maintenance and planning easier. However, every time an additional CSS file is introduced, a connection request will be added to the server. When the number of visits is large, a trade-off needs to be made between maintainability and performance.

Using the @import method to load will cause the CSS file to be loaded only after the HTML page is loaded. That is to say, before the CSS file is loaded, the page will run naked, but the response speed will be faster when entering the website. !
