58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

DSL course references

Disclaimer: the boundaries of what really qualifies as "domain-specific" as opposed to "somewhat specialized or different" isn't always crisp, so I'm casting a slightly wide net.

Courses

• Terra - a language for making high-performance DSLs - staged programming/macro-based embedding - Lua + macros + LLVM
• Scala LMS - type-based embedding - types!!!

This is a simple, should-be-drop-in replacement for the old /System/Library/Printers/Libraries/quartzfilter utility which went away circa OS X 10.8.

Usage:

chmod +x quartzfilter.js
./quartzfilter.js infile.pdf filter.qsfilter outfile.pdf

e.g.,

./quartzfilter.js my-big-pdf.pdf "/System/Library/Filters/Reduce File Size.qfilter" my-less-big-pdf.pdf
