Most websites these days are implimented using rem
units of measure. This allows components and elements conform better to the environment they are being rendered in. It seems that all UI design tools sort of ignore this aspect of implimentation, everything always seems to be shown in px
and a developer needs to know what the base font size has been set to and then manually calculate what the rem
value would be.
What would maybe be useful is to have a base font size defined in the project settings, and then be able to show both the defined px
value as well as the calculated rem
value for that setting. For instance, if the base font size was set to 16px
and the designer set a border radius of a button to 4px
it could show the defined value as well as the calculated 0.25rem
that the developer could use when building that button component.
