Description
This element is used to create a block of text. The text can be set either with the value attribute or by placing text inside the open and close description tags. The value attribute is used to set text that appears in a single line. If text appears as a child of the description, it will wrap to multiple lines. If may contain arbitrary markup, which can be styled as needed.

accesskey
Type: character
This should be set to a letter that is used as a shortcut key. This letter should be one of the characters that appears in the label text for the description. This letter will typically be drawn underlined, although this behavior will be platform and theme specific. When the user presses ALT (or a similar key that varies on each platform) and the access key, the description will be activated from anywhere in the window. Although the value is case insensitive, a letter with the case matching the accesskey attribute will used if both cases exist in the label.
control
Type: element id
This attribute may be used to associate a description with an element. For instance, this description may be spoken when the associated element is focused.
crop
Type: one of the values below
If the label of the description is too small to fit in its given space, the text will be cropped on the side specified by the crop attribute. An ellipsis will be used in place of the cropped text. If the box direction is reversed, the cropping is reversed.
- start: The text will be cropped on its left side.
- end: The text will be cropped on its right side.
- left: (Deprecated) The text will be cropped on its left side.
- right: (Deprecated) The text will be cropped on its right side.
- center: The text will be cropped on both sides.
- none: The text will be not be cropped using an ellipsis. However, the text will simply be cut off if it is too large. The side depends on the CSS text alignment.
disabled
Type: boolean
Indicates whether the description is disabled or not. If this attribute is set to true, the description is disabled. This is usually drawn with the text in grey. If the description is disabled, it does not respond to user actions. The element cannot be focused and the command event will not fire. The element will still respond to mouse events. To enable the description, leave the attribute out entirely as opposed to setting the value to false.
value
Type: string
The text to be used for the description. The text will appear on a single line and will not wrap. Normally, you would not use a value attribute on a description element and instead place the text as the content inside the description tag.
Style Classes:
The following classes may be used to style the element. These classes should be used instead of changing the style of the element directly since they will fit more naturally with the user's selected theme.
header
A class used for headings. Typically, this will cause the text to appear bold.
indent
This class causes the text to be indented on its left side.
monospace
This class causes the text to be displayed in a monospace font.
plain
This class causes the text to be displayed with no border or margin.
small-margin
This class causes the text to be displayed with a smaller margin.
