There are three different methods to add CSS styles to the HTML document. These are:

1. Inline CSS:

Inline CSS is a method of styling where CSS properties are directly applied to HTML elements within the body section using the style attribute.

<h1 style="color: green;">w3wiki</h1>

2. Internal CSS:

Internal CSS is used when a single HTML document must be styled uniquely. The CSS rule set is embedded within the HTML file in the head section using the <style> tag.

HTML

<!DOCTYPE html>
<html>

<head>
    <title>Internal CSS</title>
    <style>
        h1 {
            color: green;
        }
    </style>
</head>

<body>
    <h1>w3wiki</h1>
</body>

</html>

3. External CSS:

External CSS involves creating a separate CSS file that contains only style properties. This file is linked to the HTML document using the <link> tag.

/* This will be separate file, for example style.css */
<style>
    h1 {
       color: green;
    }
</style>
