[code editor] Font size

[harold]

First, thanks for this awesome project, it's legit.

This block has both a .html file and a .csv file:

• https://blockbuilder.org/harold/e373e0a31725c36cfe3aa528cb8e47e0

On my screen, when editing the html file, the text is really big, and I'd like to be able to shrink it to see more code on the screen at once.

Interestingly, when editing the csv file, the text is more normal size.

I experimented with using browser zoom to shrink the code, but that shrinks the output too, which is undesirable in some cases.

Anyway, independent control over the font size in the text editors would be nice.

Thanks in advance for your time and consideration.
