How to include CSS in HTML Pages

CSSWeb DevelopmentFront End TechnologyHTML

We can include CSS in HTML pages in three ways. These are −

  • Inline

    Here we specify CSS styles in the style attribute of element. However, it is recommended to internal or external linking of CSS to modularize files.

  • Internal

    We can include our CSS specifications in the <style> tag inside <head> of the HTML document.

  • External

    We can link .css files which may be placed locally or on server using the <link> tag. Refactoring files by using external linking of files allows us to have a common CSS file which can be used across multiple webpages.

Syntax

The syntax for including CSS files in HTML is as follows

/*inline*/
<element style="/*declarations*/"></element>
/*internal*/
<head>
<style>
/*declarations*/
</style>
</head>
/*external*/
<head>
<link rel="stylesheet" href="#location">
</head>
