This site is served by scripts.mit.edu. The content is generated by Jekyll, styled with Pure.css and typeset in Fira, featuring several Font Awesome icons. Practical Typography influenced the site design significantly. The specific
background-image: linear-gradient trick for styling links comes from CSS-Tricks.com.
I attempt to test this site semiregularly with the W3C validator and the Web Accessibility Evaluation Tool (WAVE). There is some RDFa markup, tested with Google’s structured data testing tool, but this is much less complete.
All source code and markup is handcrafted in Vim.
