Support for new css units ( dvh and svh )

[HOSEIN79]

Please support the new css units (svh and dvh). Currently these units are supported in other major browsers.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Firefox already does support those units.

Your caniuse search there is catching several dvh-related features, and the one that happens to be shown at the top of the page is specifically about whether those units are supported **within the CSS Houdini Typed OM API**, and Firefox is shown as not-supporting-them-there because Firefox doesn't yet support Houdini Typed OM at all.  That's tracked in https://bugzilla.mozilla.org/show_bug.cgi?id=1278697 and doesn't have any special relationship to these units in particular.

Anyway, bottom line is, these units should already work anywhere that you can use any other CSS length unit (e.g. `px`, `em`, etc.) in Firefox.  Here's a trivial jsfiddle example that you can try to see for yourself:

I can confirm that dvh, svh, and lvl are not working in mobile safari.

Almost 2025 and FF is still the only browser to not support these units which make making any layout better on mobile 😮
