Summary
The CSS text-decoration-color property sets the line color used when drawing underlines, overlines, and strikethrough lines specified by the corresponding text-decoration-line property. The color specified will be the same for all three line types.
CSS does not provide a direct mechanism for specifying a unique color for each line type. This effect can nevertheless be achieved by nesting markup elements, applying a different line type to each element (via the text-decoration-line property), and specifying the line color (via text-decoration-color) on a per‐element basis.
| Initial value | currentColor |
|---|---|
| Applies to | all elements. It also applies to ::first-letter and ::first-line. |
| Inherited | no |
| Media | visual |
| Computed value | If the value is translucent, the computed value will be the rgba() corresponding one. If it isn't, it will be the rgb() corresponding one. The transparent keyword maps to rgba(0,0,0,0). |
| Animation type | a color |
| Canonical order | the unique non-ambiguous order defined by the formal grammar |
Syntax
/* <color> values */ text-decoration-color: currentColor; text-decoration-color: red; text-decoration-color: #00ff00; text-decoration-color: rgba(255, 128, 128, 0.5); text-decoration-color: transparent; /* Global values */ text-decoration-color: inherit; text-decoration-color: initial; text-decoration-color: unset;

<hsl()> = hsl( <hue>, <percentage>, <percentage> )
<hsla()> = hsla( <hue>, <percentage>, <percentage>, <alpha-value> )

Examples
.example {
text-decoration: underline;
text-decoration-color: red;
}
The example above has the same effect as the following code, which also adds a hover style.
<!DOCTYPE html>
<html>
<head>
<style>
.example {
font-size: 24px;
text-decoration: underline;
color: red;
}
.example:hover {
color: blue;
text-decoration: line-through;
}
</style>
</head>
<body>
<span class="example">
<span style="color:black;">black text with red underline and blue hover</span>
</span>
</body>
</html>
