eox-jsonform css variables or default style changes

[santilland]

For me it seems like the eox jsonform does not use the same font configuration as other elements and i think it would be good to review and either change some defaults or providing css variables to change some aspects. I think this can be seen in following example image.
The "titles" of fields seem to have the fixed font-size of 14px, stac info and layer control use font-size "small", i think the margins also feel larger.
Not sure if we should think about alignment, we also tend to shift sub content in, so having the title and the content on the same level seems not aligned with the rest.
It seems that the description property of the jsonform is also bold as can be seen in the screenshot [kWh/m²/day], so probably would be good to not have descriptions in bold. Or if it was indented it would be clearer that it is part of the Global horizontal irradiation title.
