I'm not a professional web developer. I just discovered Semantic UI today. Looks like exactly what I need for my next project. There's one thing I'd like to get clarified. In the GitHub README, it says the supported browsers are:
Last 2 Versions FF, Chrome, Safari Mac
It's not clear which specific versions we are talking about here, because that would depend on when it was written.
My questions are:
How well does Semantic UI behave in older versions of these browsers that are still in use?
If not so well, should I care about this (meaning the number of users would be insignificant)?
