I just want to share some quick CSS recommendations for tabs on the site. The tabs overlap and font size are a bit disproportional. In forms they just look like a mash of grey. See attached images. I made some css changes to ".tab" for the css coming for "xenforo,form,public". See overrides.css. To test just create a "Local override" in your browser that matches the "xenforo,form,public" in the url.
On what device do you see this? What size screen? What browser? I certainly do not see any problems on my PC monitors, this one is 19" 1280x1024 (yes I prefer 4:3 monitors and at home is a 23" HD 1920x1080.
