CSS Grid (Grid) has been out for some time now, with full support in major modern browsers. I’ll leave others to dive into why it’s so great and what new design possibilities it makes so easy to explore. If you have been looking for the best way to support responsive web designs, I’ve yet to see anyone that doesn’t love Grid. It’s simple to use, yet extremely powerful and flexible.

But, I hear you say, a lot of our users aren’t using the most up-to-date browser versions, or are in markets where Chrome/Firefox don’t hold a majority share. And, really, is re-writing all our old code really worth it?
