What is the difference between ordered list and unordered list explain with example?

Unordered Lists

Making your own unordered list is straightforward. You just wrap an unordered list tag, or ul tag, around your list items, which use li tags. This will create a list of related items without being in a particular order.

<!DOCTYPE html> <html> <head> <title>Unordered List</title> </head> <body> <h2>Things that are cool:</h2> <ul> <li>Memes</li> <li>Food</li> <li>Coding</li> </ul> </body> </html>
How an unordered list looks like.

Ordered Lists

To turn our unordered list into an ordered one requires just changing the wrapper tag from ul (for unordered list) to an ol tag (ordered list). This will create an ordered list of related items.

<!DOCTYPE html> <html> <head> <title>Ordered List</title> </head> <body> <h2>How to become a great developer:</h2> <ol> <li>Read all the content on Sabe</li> <li>Practice, practice, practice.</li> <li>Stay curious. Ask questions. Never stop learning.</li> </ol> </body> </html>

HTML Lists

In this tutorial you will learn how to create different types of lists in HTML.

Unordered, Ordered, and Description Lists in HTML

Lists are used to store data or information in web pages in ordered or unordered form. HTML supports several types of list elements that can be included in the <BODY>tag of the document. These elements may also be nested, i.e, the onset of elements can be embedded within another. There are three types of list are available in HTML:

  • Unordered List
  • Ordered List
  • Description list

Now before moving to the list first of all we understands what is a list item tag.

List Item tag

List item tag is used to define each item of a list. Once we define list items with the <li> tag, the list appears in Web browsers in the bulleted form (by default). It is used inside both ordered and unordered list.

Syntax:

<li> content </li>



Attribute of item tag:

value: The value attribute of the<li> tag is used to specify the value of the first item. The value must be a number and this can be used in case of ordered list only. The subsequent list items will increment the value form the number.

Syntax:

<li value = number>

Example 1:

HTML




<html >
<head>
<title>inline style attribute</title>
</head>
<body>
<li>sachin</li>
<li>sujay</li>
<li>Amraditya</li>
<li>shivam</li>
<li>Parth</li>
</body>
</html>

Output:

Example 2:

HTML




<html >
<head>
<title>inline style attribute</title>
</head>
<body>
<ol>
<li value="51">English</li>
<li>Hindi</li>
<li>Maths</li>
<li>Science</li>
<li>social science</li>
</ol>
</body>
</html>

Output:

Now we will discuss all the list provided by the HTML one-by-one in detail:

Ordered list

An ordered list defines a list of items in which the order of the items are matters. An ordered list is also called a number list. The ordering is given by a numbering scheme, using Arabic numbers, letters, roman numerals. Or in other words, ordered list tag is used to create ordered list.

Syntax:

<ol> content </ol>

Attributes of ordered list:

1. reversed: This attribute is used to specifies that the ordered of the list should be reversed.

Syntax:

<ol reversed>

2. start: This attribute is used to specifies the start value of the list.

Syntax:

<ol start = “number”>

3. type: This attribute is used to specifies the type of list item maker. The value of this attribute is decimal(Default)/lower-roman/upper roman/lower-alpha/upper alpha

Syntax:

<ol type = “1|b|A|i|I”>

Example 1:

HTML




<html>
<head>
<title>ordered list</title>
</head>
<body>
<h2>Example of ordered list in default</h2>
<ol >
<li>Sachin</li>
<li>Manoj</li>
<li>Parth</li>
<li>sujay</li>
<li>Amraditya</li>
</ol>
</body>
</html>

Output:

Example 2:

HTML




<html>
<head>
<title>ordered list</title>
</head>
<body>
<h2>Example of ordered list whose type = "A"</h2>
<ol type="A">
<li>Sachin</li>
<li>Manoj</li>
</ol>
<h2>Example of reverse ordered list</h2>
<ol reversed>
<li>Parth</li>
<li>sujay</li>
</ol>
<h2>Example of ordered list start from 10</h2>
<ol start = "10">
<li>Pushpa</li>
<li>Purvi</li>
</ol>
</body>
</html>

Output:

Unordered list:

An unordered list defines a list of items in which the order of the items does not. Or in other words, unordered list tag is used to create a unordered list. It is also known as bulleted list. In unordered list each element in the list is defined using <li> tag.

Syntax:

<ul> content </ul>

Attributes of unordered list:

List-style-type: This attribute is used to specifies the bullet style that will be used as the list item marker. The value of this attribute is None/disc(default)/circle/square.

Syntax:

<ul style=”list-style-type:square|disc|none;”>

Example 1:

HTML




<html>
<head>
<title>unordered list</title>
</head>
<body>
<h2>Example of unordered list in default</h2>
<ul>
<li>Sachin</li>
<li>Manoj</li>
<li>Parth</li>
<li>sujay</li>
<li>Amraditya</li>
</ul>
</body>
</html>

Output:

Example 2:

HTML




<html>
<head>
<title>unordered list</title>
</head>
<body>
<h2>Example of unordered list in circle</h2>
<ul style="list-style-type:circle;">
<li>sachin</li>
<li>manoj</li>
</ul>
<h2>Example of unordered list in disk</h2>
<ul style="list-style-type:disk;">
<li>Priya</li>
<li>Mohit</li>
</ul>
<h2>Example of unordered list in square</h2>
<ul style="list-style-type:square;">
<li>Pinky</li>
<li>Punam</li>
</ul>
<h2>Example of unordered list in none</h2>
<ul style="list-style-type:none;">
<li>Mukti</li>
<li>Dhama</li>
</ul>
</body>
</html>

Output:

Description list

Description list is a list in which each term contain its description. This tag contain <dt> and <dd> tag.

  • <dt></dt>: This tag is used to define the name or term
  • <dd><dd>: this tag is used to describe the term.

Syntax:

<dl> content </dl>

Example:

HTML




<html>
<head>
<title>Description list</title>
</head>
<body>
<h2>Example of description list</h2>
<dl>
<dt>Python:</dt>
<dd>It is a programming language</dd>
<dt>C++:</dt>
<dd>It is also a programming language</dd>
</dl>
