A Chrome extension to transform text into boustrophedons.

(Proof of concept here on Codepen)

I use JS to break up paragraph text (whatever we can find in <p> tags) into separate lines, then CSS to flip those lines and justify them properly on the page.

Sounds easy enough, but there is some tricky code to deal with hyphenated words and embedded HTML tags like links, <em>s, and <b>s.
