About ⤵

My name is Keith J. Grant. I’m a principal software engineer at Red Hat, where I work on the UI for Ansible Automation Controller. I love fiddling with CSS and building things on the web that generally scratch my own itch. This includes Sidecar, a PWA with a curated collection of my favorite cocktails; Omnibear, a micropub browser extension; and The Ultimate Budget Spreadsheet.

I’m also the author of the highly-rated book CSS in Depth, a practical guide to modern CSS for web developers. And the second edition is underway!
