Linkpost: webdev edition

A couple of useful links from and about the web

• The best CSS Grid tutorial, from cssprinciples.com. We love interactivity embedded into good old textual pages.
• HTML self-awareness from Cassidoo. A neat trick for those among us who don't use JS frameworks.
• Val Town allows you to run functions, schedule them, and build APIs using TypeScript. There is also a community sharing ready-made functions. The e-mail logging function is great for monitoring client-side-only sites.
