Hi folks, I've got a bit of a mystery here. I have an element which is in a different position on one Mac on Yosemite/Safari 8 when compared to another Mac on Yosemite/Safari 9. I've looked at the page on 4 different Macs, the 3 with Safari 9 (1 Yosemite, and 2 El Capitan) all render it correctly, but the Safari 8 Mac doesn't. The rendering bug is a small thing. It's just that in Safari 8 one button (a <li>) is approx 70-80 pixels too low. Everything else on the page is identical to the Safari 9 version. I don't know for sure it is Safari 8 that is causing the problem, but it sure looks like it. I wasn't aware that there could be any differences in CSS rendering between two new-ish versions of Safari. Any tips? Cheers!
