Lesson 3: Working with CSS

What is CSS?

CSS stands for Cascading Style Sheets. It controls the appearance of your web pages, including colors, fonts, spacing, and layout.

Example

h1 {
  color: blue;
  font-family: Arial, sans-serif;
}
p {
  font-size: 16px;
  line-height: 1.5;
}

This CSS will make all <h1> headings blue and set the font style.

How to Add CSS

• Inline – Inside the HTML element using the style attribute.
• Internal – Inside a <style> tag in the HTML file.
• External – In a separate .css file linked in the HTML head.
