CSS Tutorial for Beginners: Learn CSS Step by Step with Examples !

Are you new to CSS and wondering where to start?

This beginner-friendly tutorial introduces you to the fundamentals of CSS, including its purpose, how it enhances HTML, and the basics of selectors, properties, and values. Through step-by-step examples, you'll learn how to style text, adjust layouts, and apply colors to your web pages.

Introduction: What is HTML and Why It Matters for CSS?

Before learning CSS, it's important to understand HTML. HTML (HyperText Markup Language) is the backbone of any web page. It defines the structure of your content using elements like headings, paragraphs, links, and images.

But HTML alone isn't enough to make a website look good. That's where CSS comes in.

What is CSS?

CSS stands for 'Cascading Style Sheets'. It is used to control the 'style and layout' of HTML elements on a web page. With CSS, you can change the color, font, spacing, alignment, and even the layout of your web content.

In simple words:

HTML is the structure. CSS is the style.

CSS Syntax (With Example and Explanation)

A CSS rule is made up of a 'selector' and a 'declaration block'.

html syntax ✍

h1 {
color: blue;
font-size: 24px;
}

Meaning:

  • 'h1' is the selector - it targets all '<h1>' elements in HTML.
  • 'color: blue;' sets the text color to blue.
  • 'font-size: 24px;' sets the font size to 24 pixels.

The 'selector' tells the browser 'which element' to style.

The 'declarations' inside '{}' tell the browser 'how' to style it.

What is CSS Property and Value?

Inside a CSS declaration, you use 'properties' and 'values' to define the style.

  • Property: This is the style you want to change (like 'color', 'font-size', 'margin', etc.).
  • Value: This is the setting you give to that property (like 'blue', '24px', '10px', etc.).

Example:

Example 📄

p {
color: red;
}

  • 'color' is the 'property'
  • 'red' is the 'value'

Each property affects a specific aspect of the element, and you can combine multiple properties in one rule to style the element in different ways.

CSS Selectors (Overview)

CSS selectors are used to "select" HTML elements to apply styles.

Example:

Example 📄

p {
color: red;
}

Meaning: All '<p>' (paragraph) elements will have red text.

There are many types of selectors like:

  • Universal ('*')
  • Class ('.class')
  • ID ('#id')
  • Grouping, Descendant, Child, etc.

'(We will explore selectors in detail in a separate blog post.)'
