MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

The text-decoration CSS property is used to set the text formatting to underline, overline or line-through. Underline and overline decorations are positioned under the text, line-through over it.

/* 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;

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.

Syntax

Values

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

Formal syntax

<'text-decoration-line'> || <'text-decoration-style'> || <'text-decoration-color'>

Examples

.under {
  text-decoration: underline red;
}

.over {
  text-decoration: wavy overline lime;
}

.line {
  text-decoration: line-through;
}

.plain {
  text-decoration: none;
}

.underover {
  text-decoration: dashed underline overline;
}

.blink {
  text-decoration: blink;
}
<p class="under">This text has a line underneath it.</p>
<p class="over">This text has a line over it.</p>
<p class="line">This text has a line through it.</p>
<p>This <a class="plain" href="#">link will not be underlined</a>,
    as links generally are by default. Be careful with removing
    the text decoration on anchors since users often depend on
    the underline to denote hyperlinks.</p>
<p class="underover">This text has lines above <em>and</em> below it.</p>
<p class="blink">This text might blink for you,
    depending on the browser you use.</p>
