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>
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>
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>
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>
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>
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>
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>
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>
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>
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>
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>
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>
