Use ol element to create ordered list
Description
The ol element denotes an ordered list.
The items in the list are denoted using the li element.
The reversed attribute has been added in HTML5.
The compact attribute is now obsolete in HTML5.
Example
The following code shows the ol element
being used to create a simple ordered list.
<!DOCTYPE HTML>
<html>
<body>
I like:<!--from ww w. j a v a 2s . c o m-->
<ol>
<li>HTML</li>
<li>CSS</li>
<li>XML</li>
</ol>
</body>
</html>
Attribute
You can control the items in the list using the attributes defined by the ol element.
The start attribute defines the ordinal value of the first item in the list.
If this attribute is not defined, the first item is assigned the ordinal value of 1.
You use the type attribute to indicate
which marker should be displayed next to each item.
The following table shows the supported values for this attribute.
| Value | Description | Example |
|---|---|---|
| 1 | Decimal numbers (default) | 1., 2., 3., 4. |
| a | Lowercase Latin characters | a., b., c., d. |
| A | Uppercase Latin characters | A., B., C., D. |
| i | Lowercase Roman characters | i., ii., iii., iv. |
| I | Uppercase Roman characters | I., II., III., IV. |
