Adding CSS to HTML

What Is It?

CSS changes how HTML looks: colors, sizes, spacing, and layout.

What the Tags Mean

• style: holds CSS rules in head.
• style attribute: styles one element.
• link rel="stylesheet": loads a CSS file.

Example 1

Save each example as index.html and open it in your browser. Each code block is a complete page.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Adding CSS to HTML</title>
 
</head>
<body>
<p style="color: blue">This sentence is blue.</p>
</body>
</html>

What you see: The paragraph uses blue text.

Example 2: Another Use

Use a style element when several paragraphs need the same rule.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Adding CSS to HTML</title>
<style>
  p { color: green; }
</style>
</head>
<body>
<p>First paragraph</p>
<p>Second paragraph</p>
</body>
</html>

Simple Tip

HTML says what the content is. CSS says how it looks.
