HTML Lists

HTML List Example

An Unordered List:

  • Item
  • Item
  • Item
  • Item

An Ordered List:

  1. First item
  2. Second item
  3. Third item
  4. Fourth item

Unordered HTML List

An unordered list starts with the <ul> tag. Each list item starts with the <li> tag.

The list items will be marked with bullets (small black circles) by default:

Example

<ul> <li>Coffee</li> <li>Tea</li> <li>Milk</li> </ul>

Unordered HTML List - Choose List Item Marker

The CSS list-style-type property is used to define the style of the list item marker:

value Description
disc Sets the list item marker to a bullet (default)
circle Sets the list item marker to a circle
square Sets the list item marker to a square
none The list items will not be marked

Example - Disc


<ul style="list-style-type:disc;">
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ul>

Example - Circle


<ul style="list-style-type:circle;">
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ul>

Example - Square


<ul style="list-style-type:square;">
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ul>

Example - None


<ul style="list-style-type:none;">
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ul>

Ordered HTML List

An ordered list starts with the <ol> tag. Each list item starts with the <li> tag.

The list items will be marked with numbers by default:

Example


<ol>
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ol>

Ordered HTML List - The Type Attribute

The type attribute of the <ol> tag, defines the type of the list item marker:

Type Description
type="1" The list items will be numbered with numbers (default)
type="A" The list items will be numbered with uppercase letters
type="a" The list items will be numbered with lowercase letters
type="I" The list items will be numbered with uppercase roman numbers
type="i" The list items will be numbered with lowercase roman numbers

Numbers:


  <ol type="1">
  <li>Coffee</li>
  <li>Tea</li>
  <li>Milk</li>
  </ol>
  

Uppercase Letters:


    <ol type="A">
    <li>Coffee</li>
    <li>Tea</li>
    <li>Milk</li>
    </ol>
    

Lowercase Letters:


      <ol type="a">
      <li>Coffee</li>
      <li>Tea</li>
      <li>Milk</li>
      </ol>
      

Uppercase Roman Numbers:


        <ol type="I">
        <li>Coffee</li>
        <li>Tea</li>
        <li>Milk</li>
        </ol>
        

Lowercase Roman Numbers:


          <ol type="i">
          <li>Coffee</li>
          <li>Tea</li>
          <li>Milk</li>
          </ol>
          

HTML Description Lists

HTML also supports description lists.

A description list is a list of terms, with a description of each term.

The <dl> tag defines the description list, the <dt> tag defines the term (name), and the <dd> tag describes each term:

Example


  <dl>
  <dt>Coffee</dt>
  <dd>- black hot drink</dd>
  <dt>Milk</dt>
  <dd>- white cold drink</dd>
  </dl>
  

Nested HTML Lists

List can be nested (lists inside lists):

Example


  <ul>
  <li>Coffee</li>
  <li>Tea
    <ul>
      <li>Black tea</li>
      <li>Green tea</li>
    </ul>
  </li>
  <li>Milk</li>
</ul>

Note: List items can contain new list, and other HTML elements, like images and links, etc.

Control List Counting

Example

<ol start="50">
  <li>Coffee</li>
  <li>Tea</li>
 <li>Milk</li>
</ol>

Horizontal List with CSS

HTML lists can be styled in many different ways with CSS.

One popular way is to style a list horizontally, to create a navigation menu:

Example

<!DOCTYPE html>
<html>
<head>
<style>
ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: #333333;
}

li {
  float: left;
}

li a {
  display: block;
  color: white;
  text-align: center;
  padding: 16px;
  text-decoration: none;
}

li a:hover {
  background-color: #111111;
}
</style>
</head>
<body>

<ul>
  <li><a href="#home">Home</a></li>
  <li><a href="#news">News</a></li>
  <li><a href="#contact">Contact</a></li>
  <li><a href="#about">About</a></li>
</ul>

</body>
</html>
