Author note

Hello everyone, my name is Sebastian. I've designed Microthemer for developers as well as beginners. My aim is to level up beginners by exposing the CSS code Microthemer generates when using the visual controls. This is of course helpful for developers who may wish to make manual edits. Some developers use Microthemer as an in-browser CSS or Sass editor, and just lean on the interface for element selection or visual properties like filters.

I've been happily developing Microthemer and supporting users of varying technical experience in my forum for many years now. I'm always ready to answer questions about the software and help out with CSS hurdles. Please don't hesitate to get in touch!
