Specification

https://drafts.csswg.org/css-text-decor-4/#text-decoration-skip-spaces-property

Summary

The text-decoration-skip-spaces CSS property controls whether text decoration lines (underlines, overlines, line-throughs, etc.) skip over whitespace characters. This allows authors to prevent decorations from being drawn under spaces, which is often more visually appealing.

Blink component

Blink>CSS

Web Feature ID

text-decoration

Motivation

Currently there is no web standard way to control whether text decorations (underlines, overlines, line-throughs) appear over whitespace characters. Authors commonly want to suppress the underline under leading/trailing spaces in inline elements, but CSS provides no mechanism for this. The `text-decoration-skip-spaces` property fills this gap, allowing precise control over decoration rendering around whitespace. This is useful for navigation menus, links, and any text where the decoration should visually attach only to non-space characters.

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
