Types of Lists in HTML

1. Ordered List (<ol>)

An ordered list is used when the sequence of items is important. Each item is numbered automatically.

<ol>
  <li>HTML</li>
  <li>CSS</li>
  <li>JavaScript</li>
</ol>
            

2. Unordered List (<ul>)

An unordered list displays items with bullet points. It's used when the order does not matter.

<ul>
  <li>Apple</li>
  <li>Banana</li>
  <li>Cherry</li>
</ul>
            

3. Description List (<dl>)

A description list is used for name/value pairs, like terms and their definitions.

<dl>
  <dt>HTML</dt>
  <dd>A markup language for creating web pages.</dd>
  <dt>CSS</dt>
  <dd>A style sheet language used to describe the appearance of web pages.</dd>
</dl>
            

List Nesting Example

Lists can be nested inside each other for complex structures:

<ul>
  <li>Frontend
    <ul>
      <li>HTML</li>
      <li>CSS</li>
    </ul>
  </li>
  <li>Backend</li>
</ul>
            

Accessibility Tips

• Use semantic list tags (<ol>, <ul>, <dl>) for structure and screen readers.
• Keep nesting levels minimal for readability and accessibility.
• Include descriptive text to clarify list items where needed.
