On latest firefox on windows causes a lot of lag and spikes CPU usage - not sure who's fault that is tbh.

I tried it on mobile/Mac (Chrome) and loaded fine. A few people were making a similar statement on Twitter though.

It's 2,000 lines of "complex" CSS, so I can see that it might cause some performance related issues.
