The meaning of link tag in css

In CSS, the link tag is used to link to external style sheet files and apply the style sheet to the HTML document. By adding a link tag in the section of an HTML document, you can specify the path and type of an external stylesheet ("stylesheet", "text/css"), thereby applying styles from the stylesheet to elements in the document.

The meaning of the link tag in CSS

The link tag is used in CSS to link to external style sheet files. Style sheets can be applied to HTML documents through the link tag.

Syntax

<link rel="stylesheet" type="text/css" href="stylesheet.css">

Attributes

• rel: Specifies the type of file. For CSS, the value is "stylesheet".
• type: Specifies the MIME type of the file. For CSS, the value is "text/css".
• href: Specify the path and name of the external style sheet file.

Purpose

The link tag allows stylesheets to be referenced from an external file rather than embedded directly into the HTML document. This provides the following advantages:

• Code maintainability: Separates style from content, making code easier to maintain.
• Reusability: Style sheets can be reused by multiple HTML documents, reducing duplicate code.
• Performance: By loading style sheets from external files, you can reduce the amount of data required when loading an HTML document, thereby increasing page load speeds.

Specific example

To apply an external style sheet named "stylesheet.css" to an HTML document, you can use the following link tag:

<link rel="stylesheet" type="text/css" href="stylesheet.css">

When this tag is added to the section of an HTML document, the styles defined in the style sheet will be applied to elements in the document.
