Closes #2008

I proposed a few small changes.

I assume that the changes to the spacing and sizes have been validated by the designers right?

The changes in the spacing are due to some adjustments to make it look more alike the design version in Figma. The height of the option goes from 31.8px to 32px, which is its value in the designs and also in our specifications!
