Some suggestions:
1. To get a real DOS feeling, the number of characters per line should be limited to (exactly) 80, and the font size should be increased accordingly.
2. Links to headers [1] within the document make the browser scroll to the header text itself, rather than the top of the surrounding colored box.
3. This is mostly a "QBasic" style. There are other styles, such as:
3.1. The "Turbo Vision" style (used by the Turbo Pascal IDE itself, and many other Turbo Pascal applications using the Turbo Vision framework.)
3.2. The "Norton Commander / Nortin Utilities" style
3.3. The "DOS command line" style (command.com)
etc.

Norton Utilities did play some interesting games with modifying the VGA character set in real time, implementing a mouse cursor over the text mode. But it was still 80x25.
However, some if the programs adapted to 80x50 if you enabled that mode before (or while?) starting them.
2. it's a bug ... I'll fix it
3. sure. it's the microsoft style to be more specific. the manufacturers had their own 'branding' in this sense. I had to pick one of them due to time being a finite resource.
(it does seem to use one of these for me, seemingly via "font-family: DOS")

I wish somebody extended it, covering more classic themes: Turbo Pascal 5 (the blue theme like this), Turbo Pascal 3 (the black / gray / yellow theme), SuperCalc, Word for DOS, etc.
A special challenge would be fitting a theme into the 4-color CGA modes (red/green and purple/blue), complete with low-res proportional fonts and pixelation grids over pictures.

Nice work!
But no, I'm glad those days are long gone. I never want to see any of my old dBASE, Clipper, Pascal code again...
Maybe it's just the nostalgia talking, but I really like this look.
