No change on font-size and low space between label and swatches

Hello! When I change the default font size in “swatches profile” -> “Default styling” -> “font size” of “Color design” and “image design”, the font doesn’t change its size; the same for the color.

On the other hand, I would lie to have more space between text and swatches, as I show in the attached image. How can I do it? Maybe some CSS? Could you write me exactly what to put inside CSS field to enlarge this space? I want to display the text in a unique line.

Thank you very much
