REM vs. PX in widgets

Hello,
in my widgets I have a mixture of REM and PX size declarations.
I learned that REM depends on the font-size and therefore is better for correct scaling.

But also the other stuff in my widgets scales fine when using the Zoom-function of the browser.
So when does this matter? Or this it matter at all for OH widgets?

Bernd

I guess the answer is a clear “It depends” :wink:
