CSS grid garden
This makes me sad.  Not because I don't like grid.  But because two weeks ago I found out that a very senior person in the company has a computer running IE11, and will not let IT upgrade her machine.<p>She recently discovered that one of the company's web sites doesn't look right in IE11, and shit ran downhill into my lap.  I checked the logs, and yep... she's the only IE11 machine to hit any of the web sites in a year.<p>I spent a day and a half downgrading the site from CSS grid to Flexbox only to discover that once I found an old machine in a closet that has IE11 on it that I could test with that IE11 doesn't fully support Flexbox, either!<p>Solution:  Each building on campus has its own IP address.  Connections from her building get a table version.
