HTML provides six levels of headings: <h1> through <h6>.
They structure content hierarchically, from the most important to the least, aiding readability and semantic markup.
Text
Paragraphs are marked with <p>. Line breaks use <br>, and thematic breaks use <hr>. These elements structure running text and improve readability.
Emphasis
HTML provides various elements for emphasis and special formatting: <strong> for important content, <em> for emphasized content, <code> for code snippets, <pre> for preformatted text, and <mark> to highlight text.
Example
The following is an example using the previously mentioned tags.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Example: Text & Headings</title>
</head>
<body>
<h1>This is an H1 heading</h1>
<h2>This is an H2 heading</h2>
<p>This is a paragraph with normal text.</p>
<p>Here is a line break<br>directly after.</p>
<hr>
<strong>This is important text</strong>
<em>This is emphasized text</em>
<code>ExampleCode()</code>
<pre>Preformatted text</pre>
<mark>Highlighted text</mark>
