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:ValueDescriptiondiscSets the list item marker to a bullet (default)circleSets the list item marker to a circlesquareSets the list item marker to a squarenoneThe list items will not be marked
Example - Disc

</ul>

</ul>Tr
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:TypeDescriptiontype="1"The list items will be numbered with numbers (default)type="A"The list items will be numbered with uppercase letterstype="a"The list items will be numbered with lowercase letterstype="I"The list items will be numbered with uppercase roman numberstype="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
By default, an ordered list will start counting from 1. If you want to start counting from a specified number, you can use the start attribute:
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><ahref="#home">Home</a></li>
<li><ahref="#news">News</a></li>
<li><ahref="#contact">Contact</a></li>
<li><ahref="#about">About</a></li>
</ul>
</body>
</html>
