Question

Is there a way to change the height of the text selection highlight without changing the line-height of the element that contains it?

Thanks.

If you what to do this with CSS only the the answer is NO.

Only a small subset of CSS properties can be used in a rule using ::selection in its selector: color, background, background-color and text-shadow. Note that, in particular, background-image is ignored, like any other property. https://developer.mozilla.org/en-US/docs/CSS/::selection
