text-decoration-color

The text-decoration-color CSS property sets the color of decorations added to text by text-decoration-line.

The color applies to decorations, such as underlines, overlines, strikethroughs, and wavy lines like those used to mark misspellings, in the scope of the property’s value.

CSS does not provide a direct mechanism for specifying a unique color for each line type. This effect can nevertheless be achieved by nesting elements, applying a different line type to each element (with the text-decoration-line property), and specifying the line color (with text-decoration-color) on a per-element basis.

It is important to ensure that the contrast ratio between the color of the text, the background the text is placed over, and the text decoration line is high enough that people experiencing low vision conditions will be able to read the content of the page. Color contrast ratio is determined by comparing the luminosity of the text and background color values.

Syntax example: text-decoration-color: currentColor;
