HTML: The Ultimate Beginner’s Guide
Chapter 3: Working with Text, Headings, and Structure
🧠 Why This Chapter
Matters
HTML is all about content and structure. In this
chapter, you’ll learn how to:
- Use
text elements properly
- Organize
content hierarchically with headings
- Create
readable paragraphs, lists, and line breaks
- Understand
the difference between block vs inline elements
- Write
well-nested, accessible, and semantic HTML
These fundamentals shape the readability, accessibility, and
SEO performance of your website.
✅ 1. Basic HTML Structure and
Elements (Quick Refresher)
Here’s the minimal HTML5 structure:
<!DOCTYPE
html>
<html>
<head>
<title>Document Title</title>
</head>
<body>
<h1>Page Heading</h1>
<p>Paragraph content goes
here.</p>
</body>
</html>
✅ Always include:
- <!DOCTYPE
html> at the top
- Root
<html> tag
- <head>
for metadata
- <body>
for content
✅ 2. Working with Text and
Headings
🔹 Headings
<h1>Main Title</h1>
<h2>Subheading</h2>
<h3>Sub-subheading</h3>
|
Tag |
Purpose |
|
<h1> |
Primary heading (once per page) |
|
<h2>–<h6> |
Nested subheadings for structure |
✅ Use headings hierarchically for
both readability and SEO.
🔹 Paragraphs
<p>This
is a paragraph of text.</p>
Paragraphs create space and structure around blocks of text.
Avoid placing block elements inside <p> tags.
✅ 3. Line Breaks and Horizontal
Rules
<p>First
line.<br>Second line.</p>
<hr>
|
Tag |
Description |
|
<br> |
Inserts a single line break |
|
<hr> |
Inserts a horizontal rule/separator |
✅ Use <br> sparingly
— prefer paragraphs or block elements for spacing.
✅ 4. Bold, Italic, and Emphasized
Text
<strong>This
is important!</strong>
<em>This
is emphasized.</em>
<b>Bold</b>
<i>Italic</i>
|
Tag |
Semantic? |
Use Case |
|
<strong> |
✅ |
Screen readers read it as important |
|
<em> |
✅ |
Emphasis with accessibility |
|
<b> |
❌ |
Bold, no semantic meaning |
|
<i> |
❌ |
Italic, no semantic meaning |
✅ Prefer semantic tags
(<strong>, <em>) for accessible content.
✅ 5. Lists (Ordered, Unordered,
and Definition)
🔹 Unordered List
(bullets)
<ul>
<li>HTML</li>
<li>CSS</li>
</ul>
🔹 Ordered List (numbers)
<ol>
<li>Step 1</li>
<li>Step 2</li>
</ol>
🔹 Definition List
<dl>
<dt>HTML</dt>
<dd>HyperText Markup
Language</dd>
</dl>
✅ Use lists to group related
items clearly.
✅ 6. Block vs Inline Elements
🔹 Block Elements
- Start
on a new line
- Take
full width
- Can
contain other block or inline elements
Examples: <div>, <p>, <section>,
<article>, <ul>, <table>
🔹 Inline Elements
- Do not
break the flow of content
- Take
only as much width as needed
Examples: <span>, <a>, <strong>,
<em>, <img>
🔹 Example:
<p>This
is <strong>bold</strong> and <em>emphasized</em> inside
a paragraph.</p>
✅ Mixing block and inline
properly ensures cleaner layouts and styling.
✅ 7. HTML Nesting & Comments
🔹 Nesting Elements
Properly
<p><strong>This
is a bold paragraph.</strong></p>
✅ Tags must be opened and
closed in order.
Incorrect nesting:
<p><strong>Bold
text</p></strong> ❌
🔹 HTML Comments
<!--
This is a comment -->
✅ Comments are ignored by
browsers but helpful for developers.
