HTML, XHTML
This technique relates to:
Assistive technologies include inconsistent support for various uses of the type attribute used to indicate numbering and bullet styles.
The objective of this technique is to create lists of related items using list elements
appropriate for their purposes. The ol element is used when the list is
ordered and the ul element is used when the list is unordered. Definition
lists (dl) are used to group terms with their definitions. Although the use
of this markup can make lists more readable, not all lists need markup. For instance,
sentences that contain comma-separated lists may not need list markup.
When markup is used that visually formats items as a list but does not indicate the
list relationship, users may have difficulty in navigating the information. An example
of such visual formatting is including asterisks in the content at the beginning of each
list item and using <br> elements to separate the list items.
Some assistive technologies allow users to navigate from list to list or item to item. Style sheets can be used to change the presentation of the lists while preserving their integrity.
This example uses an ordered list to show the sequence of steps in a process.
Example Code:
<ol>
<li>Mix eggs and milk in a bowl.</li>
<li>Add salt and pepper.</li>
</ol>This example shows an unordered list of items to buy at the store.
Example Code:
<ul>
<li>Milk</li>
<li>Eggs</li>
<li>Butter</li>
</ul>This example uses a definition list to group a definition with the term that is being defined.
Example Code:
<dl>
<dt>blink</dt>
<dd>turn on and off between .5 and 3 times per second
</dd>
</dl> Resources are for information purposes only, no endorsement implied.
Check that content that has the visual appearance of a list (with or without bullets) is marked as an unordered list.
Check that content that has the visual appearance of a numbered list is marked as an ordered list.
Check that content is marked as a definition list when terms and their definitions are presented in the form of a list.
All the checks above are true.
