Resolved value of line-height:normal will be normal instead of pixels

Published: | Categories: CSS, DOM


Starting with Firefox 71, the resolved value of the line-height CSS property will be normal instead of an actual length if the specified value is normal or undefined.

// This can now return `normal` instead of pixels

This change has already been made on the Nightly and early Beta channels since Firefox 69 after a discussion in the CSS Working Group, and Mozilla developers haven’t seen compatibility issue reports so far. The new behaviour matches Google Chrome. Safari will make the same change soon.
