CSS text-underline-offset Property

❮ Previous Reference Next ❯


p {
  text-decoration: underline;
  text-underline-offset: 1em;

Hello World!


The text-underline-offset CSS property sets the offset distance of an underline text decoration line (applied using text-decoration) from its original position.

Note: text-underline-offset is not part of the text-decoration shorthand. While an element can have multiple text-decoration lines, text-underline-offset only impacts underlining, and not other possible line decoration options such as overline or line-through.

Default value:auto
JavaScript syntax:

Standard Syntax

text-underline-offset: auto|length|percentage|initial|inherit|revert|revert-layer|unset;

Browser Support


Property Values

The following table describes the values of this property:

Value Description
auto The browser chooses the appropriate offset for underlines.
length Specifies the offset of underlines as a length, overriding the font file suggestion and the browser default. It is recommended to use em units so the offset scales with the font size.
percentage Specifies the offset of underlines as a percentage.
initial Sets this property to its default value.
inherit If specified, the associated element takes the computed value of its parent element animation-delay property.
revert Reverts the cascaded value of the property from its current value to the value the property
revert-layer Rollback styles to the ones specified in previous cascade layers.
unset Resets a property to its inherited value if the property naturally inherits from its parent, and to its initial value if not.
