CSS (Cascading Style Sheets) is essential for styling HTML elements and creating visually appealing web pages. Here's a quick guide to get you started:

1. Introduction to CSS

CSS allows you to control the presentation, formatting, and layout of web content. It works alongside HTML to define how elements should look.

  • Key Concepts:
    • Selectors (e.g., .class, #id, element)
    • Properties (e.g., color, font-size, margin)
    • Values (e.g., red, 12px, auto)

2. Basic Syntax

CSS rules are structured as:

selector { property: value; }

Example:

body {
  background-color: #f0f0f0;
  font-family: Arial, sans-serif;
}

3. Common Properties

  • Text Styling: color, font-weight, text-align
  • Layout: display, flex, grid
  • Box Model: width, height, padding, border, margin

4. Practical Example

<!DOCTYPE html>
<html>
<head>
  <style>
    .highlight {
      background-color: yellow;
      padding: 10px;
      border: 2px solid orange;
    }
  </style>
</head>
<body>
  <p class="highlight">This is a styled paragraph!</p>
</body>
</html>

5. Debugging Tips

  • Use browser developer tools (F12) to inspect elements and modify styles in real-time.
  • Check for syntax errors using tools like CSS Validator.
