Tufte CSS VS ox-tufte

As it is often said in various designer forums, please avoid pure white (#FFFFFF) on black (here #111111), as it makes the text glow for the human eyes (therefore making it unreadable for long text). Instead, try to lower a bit the contrast on the text color.

Also, the dispositions for the buttons at the beginning (GitHub, NPM, ...) are not adjusted correctly for keyboard navigation (each button requires two tabs).

Appart from that, I do like a minimalist stylesheet, so I will also recommend Tufte CSS [0] for readers.

CSS and HTML is great for documents - not so great for applications. Most sites end up implementing their own navigation UI/UX at a minimum (an application) - many end up as more applications.

For an example of "documents", see eg:

Just for kicks, I applied Tufte CSS[0] onto the page using a browser extension. Great ROI.

A famous physicist, Richard Feynman, had a practice in his his extensive writing, e.g. a three-volume physics text, to use the methodology of sentences which then cumulate sequentially into paragraphs. (ht Ed Tufte)

tufte-css made some structural changes, and ox-tufte hasn't been updated yet. You can either try to fix ox-tufte, or use an older version of tufte-css (I think v1.4 might work). See also https://github.com/dakrone/ox-tufte/issues/11
