Ubuntu mate/RasPi3 - AWS site

Hi guys,

I'm running a raspberry pi 3b, and I seem to be having issues when trying to access amazon web services website. It seems the CSS?? is broken, on both Chromium and Firefox.

I understand this is most likely a problem with compatibility but I can't find anything on the internet that might explain or fix this issue. Can anyone explain?

I attach a picture of what I mean.

Thank you.

Sam
