OListElement Interface / dart:html Library / Dart API Reference

OListElement Interface

The HTML ordered list element (<ol>) represents an ordered list of items. Typically, ordered-list items are displayed with a preceding numbering, which can be of any form, like numerals, letters or Romans numerals or even simple bullets. This numbered style is not defined in the HTML description of the page, but in its associated CSS, using the list-style-type property.

There is no limitation to the depth and imbrication of lists defined with the <ol> and <ul> elements.

Usage note: The <ol> and <ul> both represent a list of items. They differ in the way that, with the <ol> element, the order is meaningful. As a rule of thumb to determine which one to use, try changing the order of the list items; if the meaning is changed, the <ol> element should be used, else the <ul> is adequate.

Fields

Code bool compact #

This Boolean attribute hints that the list should be rendered in a compact style. The interpretation of this attribute depends on the user agent and it doesn't work in all browsers.

Usage note: Do not use this attribute, as it has been deprecated: the <ol> element should be styled using CSS. To give a similar effect than the compact attribute, the CSS property line-height can be used with a value of 80%.

from MDN

bool compact;

Code bool reversed #

This Boolean attribute specifies that the items of the item are specified in the reverse order, i.e. that the least important one is listed first. Browsers, by default, numbered the items in the reverse order too.

from MDN

bool reversed;

Code int start #

This integer attribute specifies the start value for numbering the individual list items. Although the ordering type of list elements might be Roman numerals, such as XXXI, or letters, the value of start is always represented as a number. To start numbering elements from the letter "C", use <ol start="3">.

Note: that attribute was deprecated in HTML4, but reintroduced in HTML5.

from MDN

int start;

Code String type #

Indicates the numbering type:

'a' indicates lowercase letters,
' A' indicates uppercase letters,
'i' indicates lowercase Roman numerals,
'I' indicates uppercase Roman numerals,
and '1' indicates numbers.

The type set is used for the entire list unless a different type attribute is used within an enclosed <li> element.

Usage note: Do not use this attribute, as it has been deprecated: use the CSS list-style-type property instead.

from MDN

String type;
