Using other units than pixels for $v-font-size

Max121 · September 29, 2015, 3:56pm

Hello,

i am using Vaadin-Version 7.5.6 and the Valo theme.
I tried to use “mm” as unit for the variable $v-font-size (Example: $v-font-size: 15mm;) but then i got many IncompatibleUnitsExceptions.
I tried other units like “cm” or “in” but it seems that only “px” are working without exception.
In the Book of Vaadin is written, that “It should be specified in pixels.”.
“Should” - Not “have to” (must).
So it should be working with other units too.
Is it a bug?

Here is one of the errors:
