16.3.1 Underlining, overlining, striking, and blinking:
the ’text-decoration’ property
’text-decoration’
Value: none | [ underline || overline || line-through || blink ] | inherit
Initial: none
Applies to: all elements
Inherited: no (see prose)
Percentages: N/A
Media: visual
This property describes decorations that are added to the text of an element. If
the property is specified for a block-level [p. 97] element, it affects all inline-level
descendants of the element. If it is specified for (or affects) an inline-level [p. 98]
element, it affects all boxes generated by the element. If the element has no
content or no text content (e.g., the IMG element in HTML), user agents must
ignore [p. 42] this property.
Values have the following meanings:
none
Produces no text decoration.
underline
Each line of text is underlined.
overline
Each line of text has a line above it.
line-through
Each line of text has a line through the middle
blink
Text blinks (alternates between visible and invisible). Conforming user
agents [p. 32] are not required to support this value.
The color(s) required for the text decoration should be derived from the ’color’
property value.
This property is not inherited, but descendant boxes of a block box should be
formatted with the same decoration (e.g., they should all be underlined). The
color of decorations should remain the same even if descendant elements have
different ’color’ values.
Example(s):
In the following example for HTML, the text content of all A elements acting as
hyperlinks will be underlined:
A[href] { text-decoration: underline }
16.3.2 Text shadows: the ’text-shadow’ property
’text-shadow’
