#### `text-decoration-skip-spaces`

The `text-decoration-skip-spaces` CSS property controls whether text decoration lines (such as underlines, overlines, or line-throughs) skip over white space characters.

This allows you to prevent decoration lines from being drawn on white space characters, to get more visually appealing results.
