HTML Heading Tags: A Complete Guide

Introduction: Why HTML Heading Tags Are Important

When users visit a webpage, they don’t read everything word by word.
They scan the page to understand what it’s about.

HTML heading tags help by:

Structuring content clearly
Improving readability
Helping search engines understand page hierarchy
Supporting accessibility tools like screen readers

Headings are the skeleton of your webpage content.
Without them, content becomes confusing and unorganized.

What Are HTML Heading Tags?

HTML heading tags are used to define titles and subtitles on a webpage.

HTML provides six heading levels:

<h1> to <h6>

<h1> → Most important heading
<h6> → Least important heading

👉 Headings create a content outline, just like chapters and subchapters in a book.

List of HTML Heading Tags (H1–H6)

Tag Importance Typical Use
<h1> Highest Page title
<h2> High Main sections
<h3> Medium Subsections
<h4> Lower Sub-points
<h5> Low Minor headings
<h6> Lowest Smallest heading

Tag	Importance	Typical Use
`<h1>`	Highest	Page title
`<h2>`	High	Main sections
`<h3>`	Medium	Subsections
`<h4>`	Lower	Sub-points
`<h5>`	Low	Minor headings
`<h6>`	Lowest	Smallest heading

Basic Syntax of HTML Headings

<h1>This is a Heading</h1>

Each heading:

Has an opening and closing tag
Displays text in bold by default
Adds spacing before and after automatically

Example: All Heading Levels

<h1>Main Website Title</h1>
<h2>Section Title</h2>
<h3>Subsection Title</h3>
<h4>Topic Heading</h4>
<h5>Subtopic</h5>
<h6>Small Heading</h6>

Output Explanation

Text size decreases from <h1> to <h6>
Visual size reflects importance, not styling choice

Purpose of Each Heading Level

`<h1>` – Main Heading

Represents the main topic of the page
Usually the page title

<h1>Learn HTML Headings</h1>

Best Practice: Use only one <h1> per page.

`<h2>` – Section Headings

Divides content into major sections

`<h3>` – Subsections

Used under <h2>

`<h4>` to `<h6>` – Lower-Level Headings

Used for deeper content structure
Less common but useful in long documents

HTML Headings and Accessibility

Allow users to jump between sections

Headings vs Styling (Important Rule)

Wrong:

Correct:

Headings define structure, not appearance.
Use CSS to change size and style.

Styling Headings with CSS

h1 {
  font-size: 32px;
  color: #333;
}

h2 {
  font-size: 24px;
}

This keeps HTML semantic and clean.
