Very Short Question and Answers - Lists in HTML

Ordered lists (<ol>), Unordered lists (<ul>), and Definition lists (<dl>).

The <ol> tag is used to create an ordered (numbered) list.

The <li> tag defines an individual item in both ordered (<ol>) and unordered (<ul>) lists.

The 'type' attribute (e.g., type="A", type="i") changes the numbering style.

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

By setting the type attribute to "square": <ul type="square">

<dl> for the list, <dt> for the term, and <dd> for the description.

Unordered lists (<ul>).

When creating a glossary or explaining the meanings of terms.

<ul>
  <li>Outer Item 1
    <ol>
      <li>A</li>
      <li>B</li>
    </ol>
  </li>
</ul>

The default bullet style is a solid disc.

<ol type="I">
  <li>First</li>
  <li>Second</li>
</ol>

It is invalid HTML; nested lists must be inside a <li>.

List items in a definition list are made with <dt> for the term and <dd> for the description, not <li>.

<ul>
  <li>Math
    <ul>
      <li>Algebra</li>
    </ul>
  </li>
</ul>

Ordered list (<ol>), since the order of steps matters.

<dl> and </dl>

In <ol>, it changes the numbering style; in <ul>, it changes the bullet appearance.

Use <ol type="a">

<ol> creates a numbered list while <ul> creates a bulleted list; <ol> is used when order matters, <ul> when it does not.
