<ol>: The Ordered List element

The HTML <ol> element represents an ordered list of items — typically rendered as a numbered list.

Attributes

This element also accepts the global attributes.

reversed

This Boolean attribute specifies that the list’s items are in reverse order. Items will be numbered from high to low.

start

An integer to start counting from for the list items. Always an Arabic numeral (1, 2, 3, etc.), even when the numbering type is letters or Roman numerals. For example, to start numbering elements from the letter "d" or the Roman numeral "iv," use start="4".

type

Sets the numbering type:

• a for lowercase letters
• A for uppercase letters
• i for lowercase Roman numerals
• I for uppercase Roman numerals
• 1 for numbers (default)

The specified type is used for the entire list unless a different type attribute is used on an enclosed <li> element.

Note: Unless the type of the list number matters (like legal or technical documents where items are referenced by their number/letter), use the CSS list-style-type property instead.

Usage notes

Typically, ordered list items display with a preceding marker, such as a number or letter.

The <ol> and <ul> elements may nest as deeply as desired, alternating between <ol> and <ul> however you like.

The <ol> and <ul> elements both represent a list of items. The difference is with the <ol> element, the order is meaningful. For example:

• Steps in a recipe
• Turn-by-turn directions
• The list of ingredients in decreasing proportion on nutrition information labels

To determine which list to use, try changing the order of the list items; if the meaning changes, use the <ol> element — otherwise you can use <ul>.

Examples

Simple example

<ol>
  <li>Fee</li>
  <li>Fi</li>
  <li>Fo</li>
  <li>Fum</li>
</ol>

The above HTML will output:

Using Roman Numeral type

<ol type="i">
  <li>Introduction</li>
  <li>List of Greivances</li>
  <li>Conclusion</li>
</ol> 

The above HTML will output:

Using the start attribute

<p>Finishing places of contestants not in the winners’ circle:</p>

<ol start="4">
  <li>Speedwalk Stu</li>
  <li>Saunterin’ Sam</li>
  <li>Slowpoke Rodriguez</li>
</ol>

The above HTML will output:

Nesting lists

<ol>
  <li>first item</li>
  <li>second item  <!-- closing </li> tag not here! -->
    <ol>
      <li>second item first subitem</li>
      <li>second item second subitem</li>
      <li>second item third subitem</li>
    </ol>
  </li>            <!-- Here's the closing </li> tag -->
  <li>third item</li>
</ol>

The above HTML will output:

Unordered list inside ordered list

<ol>
  <li>first item</li>
  <li>second item  <!-- closing </li> tag not here! -->
    <ul>
      <li>second item first subitem</li>
      <li>second item second subitem</li>
      <li>second item third subitem</li>
    </ul>
  </li>            <!-- Here's the closing </li> tag -->
  <li>third item</li>
</ol>
