text-decoration-line

{{CSSRef}}

The text-decoration-line CSS property sets the kind of decoration that is used on text in an element, such as an underline or overline.

{{InteractiveExample("CSS Demo: text-decoration-line")}}

text-decoration-line: none;

text-decoration-line: underline;

text-decoration-line: overline;

text-decoration-line: line-through;

text-decoration-line: grammar-error;

text-decoration-line: spelling-error;

text-decoration-line: underline overline;

text-decoration-line: underline line-through;

<section id="default-example">
  <p>
    I'd far rather be
    <span class="transition-all" id="example-element">happy than right</span>
    any day.
  </p>
</section>

p {
  font: 1.5em sans-serif;
}

When setting multiple line-decoration properties at once, it may be more convenient to use the {{cssxref("text-decoration")}} shorthand property instead.

Syntax

/* Single keyword */
text-decoration-line: none;
text-decoration-line: underline;
text-decoration-line: overline;
text-decoration-line: line-through;
text-decoration-line: blink;
text-decoration-line: spelling-error;
text-decoration-line: grammar-error;

/* Multiple keywords */
text-decoration-line: underline overline; /* Two decoration lines */
text-decoration-line: overline underline line-through; /* Multiple decoration lines */

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

The text-decoration-line property is specified as none, or one or more space-separated values from the list below.

Values

none
- : Produces no text decoration.
underline
- : Each line of text has a decorative line beneath it.
overline
- : Each line of text has a decorative line above it.
line-through
- : Each line of text has a decorative line going through its middle.
blink
- : The text blinks (alternates between visible and invisible). Conforming user agents may not blink the text. This value is deprecated in favor of CSS animations.
spelling-error
- : Each line of text uses the user agents’ method of highlighting spelling mistakes, which is a dotted red line in most browsers.
grammar-error
- : Each line of text uses the user agents’ method of highlighting grammar mistakes, which is a dotted green line in most browsers.

[!NOTE] When using spelling-error and grammar-error values, the browser disregards the other properties in the {{cssxref("text-decoration")}} shorthand (such as {{cssxref("text-underline-position")}} , color, or stroke).

Errors example

In this example, the first paragraph contains a spelling mistake and uses the browser’s styling for spelling errors on the misspelled word. The second paragraph uses the browser’s styling for grammar errors. There is no styling change in browsers that do not support these text-decoration-line values.

<p>This text contains a <span class="spelling">speling</span> mistake.</p>
<p class="grammar">This text contain grammatical errors.</p>

.spelling {
  text-decoration-line: spelling-error;
}

.grammar {
  text-decoration-line: grammar-error;
}
