Introduction to CSS

Published: 20 Aug, 2026 | Author: CCI Admin | Category: CSS

A website is not only about displaying information. A good website should also look attractive, organized, and easy to use. This is where CSS (Cascading Style Sheets) plays an important role.

What is CSS?

CSS is a styling language used to design and format web pages. It works together with HTML to control the appearance of website elements such as text, colors, backgrounds, buttons, images, and layouts.

Why is CSS Important?

HTML creates the structure of a webpage, while CSS makes that webpage visually attractive and user-friendly.

• Change text colors and fonts
• Add background colors and images
• Control spacing and sizes
• Design buttons and menus
• Create attractive layouts
• Make websites responsive

Simple CSS Example

h1 {
    color: blue;
    font-size: 36px;
}

p {
    color: gray;
    font-size: 18px;
}

In this example, CSS changes the color and size of the heading and paragraph.

How CSS Works with HTML

HTML creates the heading. CSS can then be used to change its color, font, size, alignment, background, and other visual properties.

Types of CSS

There are three common ways to apply CSS:

• Inline CSS – CSS written directly inside an HTML element.
• Internal CSS – CSS written inside the HTML page using a style tag.
• External CSS – CSS written in a separate .css file.

What Can You Create with CSS?

With CSS, beginners can create attractive web pages, navigation menus, cards, buttons, forms, landing pages, responsive layouts, and complete website designs.
