✅ Paragraphs are used for text blocks, not headings or lists.
✅ Sentences are clear and concise.
✅ Avoid ALL CAPS except for acronyms.

3. Lists

✅ Use ordered (<ol>) or unordered (<ul>) lists where appropriate.
✅ Each item is marked with <li> elements, not typed symbols.

4. Alternative Text for Images

✅ Informative images include meaningful alt text.
✅ Decorative images use empty alt ("").
✅ Avoid using images of text unless necessary.

5. Tables

✅ Tables are for data, not layout.
✅ Use <th> for headers and associate with <td>.
✅ Add <caption> when helpful for data context.

✅ Each option has a visible label.

10. Dropdown Menus

✅ Each <option> has distinct, meaningful text.

✅ Use a default prompt (e.g., “Choose an option”).

11. Expandable/Collapsible Content

✅ Sections have clear headings or labels.
✅ Use aria-expanded for toggled states.
✅ Do not hide essential content without user access method.
