Description lists connect terms with their descriptions. Dt names a term and dd provides its explanation or related value.
What You Need to Know
A description list is great for glossaries or short term-value information. It is not a substitute for a grid of data that needs row and column headers.
The goal is not to collect as many tags as possible. Pick the element that best describes what the content really is.
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.
<dl>
<dt>HTML</dt>
<dd>Language for structuring web content.</dd>
<dt>Browser</dt>
<dd>App that reads and displays webpages.</dd>
</dl>Let’s Understand the Example
- Dl contains terms and their descriptions.
- Dt introduces a term being described in a description list.
- Dd supplies the description associated with a term.
Look for the text “HTML” 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 “HTML”. 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
- Add one more HTML word with a beginner-friendly definition.
- Save your changes, open or refresh the page, and compare the result with the original example.
- Tell a friend what your change did. If you are not sure, undo it, refresh the page, and compare.
Common Beginner Mistakes
- Using ul instead of dl when every item is clearly a term-definition pair.
- Avoid picking tags just for their default bold, italic or spaced appearance. Use CSS for presentation.
