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.

/* Keyword values */
text-decoration: none;                 /* No text decoration */
text-decoration: underline red;        /* Red underlining */
text-decoration: underline wavy red;   /* Red wavy underlining */

/* Global values */
text-decoration: inherit;
text-decoration: initial;
text-decoration: unset;


The text-decoration property is a shorthand and can use the values of each of the three longhand properties: text-decoration-line, text-decoration-color, and text-decoration-style
