Summary
The text-decoration
CSS property is used to set the text formatting to underline
, overline
, line-through
or blink
. Underline and overline decorations are positioned under the text, line-through over it.
Text decorations draw across descendant elements. This means that it is not possible to disable on a descendant a text decoration that is specified on one of its ancestors. For example, in the markup <p>This text has <em>some emphasized words</em> in it.</p>
, the style rule p { text-decoration: underline; }
would cause the entire paragraph to be underlined. The style rule em { text-decoration: none; }
would not cause any change; the entire paragraph would still be underlined. However, the rule em { text-decoration: overline; }
would cause a second decoration to appear on "some emphasized words".
Note: CSS Text Decoration Level 3 transformed this property as a shorthand for the three new text-decoration-color
, text-decoration-line
, and text-decoration-style
CSS properties. Like for any other shorthand property, it means that it resets their value to their default if not explicitly set in the shorthand.
