HTML offers web authors three ways for specifying lists of information. All lists must contain one or more list elements. Lists may contain −
· <ul> − An unordered list. This will list items using plain bullets.
· <ol> − An ordered list. This will use different schemes of numbers to list your items.
· <dl> − A definition list. This arranges your items in the same way as they are arranged in a dictionary.
HTML Unordered Lists
An unordered list is a collection of related items that have no special order or sequence. This list is created by using HTML <ul> tag. Each item in the list is marked with a bullet.
Example
<!DOCTYPE html>
<html>
<head>
<title>HTML Unordered List</title>
</head>
<body>
<ul>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ul>
</body>
</html>
This will produce the following result −
The type Attribute
You can use type attribute for <ul> tag to specify the type of bullet you like. By default, it is a disc. Following are the possible options −
<ul type = “square”>
<ul type = “disc”>
<ul type = “circle”>
Example
Following is an example where we used <ul type = “square”>
<!DOCTYPE html>
<html>
<head>
<title>HTML Unordered List</title>
</head>
<body>
<ul type = “square”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ul>
</body>
</html>
This will produce the following result −
Example
Following is an example where we used <ul type = “disc”> −
<!DOCTYPE html>
<html>
<head>
<title>HTML Unordered List</title>
</head>
<body>
<ul type = “disc”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ul>
</body>
</html>
This will produce the following result −
Example
Following is an example where we used <ul type = “circle”> −
<!DOCTYPE html>
<html>
<head>
<title>HTML Unordered List</title>
</head>
<body>
<ul type = “circle”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ul>
</body>
</html>
This will produce the following result −
HTML Ordered Lists
If you are required to put your items in a numbered list instead of bulleted, then HTML ordered list will be used. This list is created by using <ol> tag. The numbering starts at one and is incremented by one for each successive ordered list element tagged with <li>.
Example
<!DOCTYPE html>
<html>
<head>
<title>HTML Ordered List</title>
</head>
<body>
<ol>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ol>
</body>
</html>
This will produce the following result −
The type Attribute
You can use type attribute for <ol> tag to specify the type of numbering you like. By default, it is a number. Following are the possible options −
<ol type = “1”> – Default-Case Numerals.
<ol type = “I”> – Upper-Case Numerals.
<ol type = “i”> – Lower-Case Numerals.
<ol type = “A”> – Upper-Case Letters.
<ol type = “a”> – Lower-Case Letters.
Example
Following is an example where we used <ol type = “1”>
<!DOCTYPE html>
<html>
<head>
<title>HTML Ordered List</title>
</head>
<body>
<ol type = “1”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ol>
</body>
</html>
This will produce the following result −
Example
Following is an example where we used <ol type = “I”>
<!DOCTYPE html>
<html>
<head>
<title>HTML Ordered List</title>
</head>
<body>
<ol type = “I”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ol>
</body>
</html>
This will produce the following result −
Example
Following is an example where we used <ol type = “i”>
<!DOCTYPE html>
<html>
<head>
<title>HTML Ordered List</title>
</head>
<body>
<ol type = “i”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ol>
</body>
</html>
This will produce the following result −
Example
Following is an example where we used <ol type = “A” >
<!DOCTYPE html>
<html>
<head>
<title>HTML Ordered List</title>
</head>
<body>
<ol type = “A”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ol>
</body>
</html>
This will produce the following result −
Example
Following is an example where we used <ol type = “a”>
<!DOCTYPE html>
<html>
<head>
<title>HTML Ordered List</title>
</head>
<body>
<ol type = “a”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ol>
</body>
</html>
This will produce the following result −
The start Attribute
You can use start attribute for <ol> tag to specify the starting point of numbering you need. Following are the possible options −
<ol type = “1” start = “4”> – Numerals starts with 4.
<ol type = “I” start = “4”> – Numerals starts with IV.
<ol type = “i” start = “4”> – Numerals starts with iv.
<ol type = “a” start = “4”> – Letters starts with d.
<ol type = “A” start = “4”> – Letters starts with D.
Example
Following is an example where we used <ol type = “i” start = “4” >
<!DOCTYPE html>
<html>
<head>
<title>HTML Ordered List</title>
</head>
<body>
<ol type = “i” start = “4”>
<li>Beetroot</li>
<li>Ginger</li>
<li>Potato</li>
<li>Radish</li>
</ol>
</body>
</html>
This will produce the following result −
HTML Definition Lists
HTML and XHTML supports a list style which is called definition lists where entries are listed like in a dictionary or encyclopedia. The definition list is the ideal way to present a glossary, list of terms, or other name/value list.
Definition List makes use of following three tags.
- <dl> − Defines the start of the list
- <dt> − A term
- <dd> − Term definition
- </dl> − Defines the end of the list
Example
<!DOCTYPE html>
<html>
<head>
<title>HTML Definition List</title>
</head>
<body>
<dl>
<dt><b>HTML</b></dt>
<dd>This stands for Hyper Text Markup Language</dd>
<dt><b>HTTP</b></dt>
<dd>This stands for Hyper Text Transfer Protocol</dd>
</dl>
</body>
</html>
