CSS Grid is a godsend, but it's only been around for about a year now. I'd like to make a responsive website that would have at most a few thousand users, and I'd love to create the layout using grid. Grid is now supported by the latest versions of all major web browsers, but there might still be some people using older browsers, and it would look broken for them. Then again, I'm of the mindset that if you're using a browser that's years out of date, then fuck you, update your browser.
I guess my question is, what percent of people are still using browsers that don't support grid layouts?
