Beginner’s Guide to CSS

CSS or Cascading Style Sheets is the language used to style HTML content. Without CSS, websites look plain and unattractive. Learning CSS is essential for web development beginners.

What is CSS?

CSS allows you to change colors, fonts, layouts, and spacing. It works together with HTML, which creates structure, while CSS adds design and visual appeal.

How to Add CSS

There are three ways to use CSS:

• Inline CSS – inside the HTML element
• Internal CSS – inside a <style> tag in the head section
• External CSS – in a separate file like style.css (recommended)

Basic CSS Example

body {
  background-color: #f9f9f9;
  font-family: Arial;
}

h1 {
  color: #111;
}

Selectors, Properties, and Values

CSS uses selectors (like h1, p, .class, #id), properties (color, font-size, margin) and values (blue, 20px, 10%).

Responsive Design

Using media queries, you can make your website mobile friendly:

@media (max-width: 600px) {
  body {
    font-size: 16px;
  }
}

Practice creating small pages and styling them with CSS. Once comfortable, move on to layouts using Flexbox and Grid.

Consistent practice will help you create professional, modern websites that visitors enjoy.
