text-decoration

The text-decoration CSS shorthand property sets the appearance of decorative lines on text. It is a shorthand for text-decoration-line, text-decoration-color, text-decoration-style, and the newer text-decoration-thickness property.

Text decorations are drawn across descendant text elements. This means that if an element specifies a text decoration, then a child element can’t remove the decoration. 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”.

Syntax example: text-decoration: underline;
