UI Font Concern - guides.rubyonrails.org

the font Helvetica specified in main.css makes readers uncomfortable
to read rails guides in firefox/xp environment.

Can we use Rails standard fonts like font-family:georgia,"Lucida
Grande",arial,helvetica,sans-serif; (I had to override with stylish to
use verdana font. )

main.css

Could you post a screenshot of the window causing that uncomfortable feeling ?

I just uploaded the screen shots. May be that 'uncomfortable feeling'
is in my personal context. thanks
