Great! Would this mean that width: 300%; in my dictionary's css should work as well? I recently discovered how to display images using lua text substitution, but had to manually upscale them to fit my needs. The css I above does not seem to work still even with the nightly, but maybe it's just the unit or something that simple?

Nope, the dictionary HTML results are not rendered by crengine, but by MuPDF (fortunately, for me :).
So, you should look at CSS support in MuPDF for what you can do (we lag, and koreader/koreader-base#1203 is paused :()
