CSS Property: text-decoration
[this page | pdf | back links]
The CSS (CSS1) text-decoration property indicates the
‘decoration’ (e.g. underlining) added to text. Note in CSS3 the text-decoration
property is supposed to be a shorthand property covering text-decoration-line,
text-decoration-color
and text-decoration-style
but at the time of writing this interpretation was not supported by major
browsers.

and initial) are:
