Strong marks text as especially important, such as a safety warning. b draws attention without adding the same importance, such as a key term in a summary.

What You Need to Know


Both often appear bold by default, but their meanings are different. Choose based on the text's purpose before styling.

Example: See It in Action


This example keeps the idea small. Copy it carefully, then follow the explanation instead of guessing what the browser will do.

This is a short HTML fragment. To try it as a webpage, put it inside the body element of a complete HTML document.

<p><strong>Warning:</strong> Keep this file private.</p>
<p>The <b>new</b> backpack comes in three colors.</p>
<p>Both look bold by default, but mean different things.</p>

Let’s Understand the Example


  • Strong marks text as particularly important. It means more than simply making words bold.
  • B draws attention without saying that the text has extra importance.
  • A p groups a paragraph of related text. Start another paragraph for a new thought.

Look for the text “Warning:” in the page. If the visible result surprises you, inspect the rendered elements to see what the browser actually built.

What Should You See?


The page should include “Warning:”. If it looks different from what you expected, open developer tools and compare the source with the elements the browser created.

Try removing one piece of markup in a scratch copy, refresh the page, and compare the behavior. This is often the fastest way to understand what that piece contributes.

Try It Yourself


  1. Mark a genuine warning with strong and a product name with b.
  2. Save your changes, open or refresh the page, and compare the result with the original example.
  3. Tell a friend what your change did. If you are not sure, undo it, refresh the page, and compare.

Common Beginner Mistakes


  • Using strong only to make an ordinary heading look heavier.
  • Avoid picking tags just for their default bold, italic or spaced appearance. Use CSS for presentation.
