hi Peter!

I found the lines where font_size was called on the gem code and just 
commented them and it worked (I realized that font_size was not used any 
more).
I did not like the result so finnally i did not used it on my project. 
Maybe you should use a javascript in order to have a nice view. If you 
find anything interesting please share it!

Regards,

Javi
