Problem with the check in forms and with the fontello fonts

In mobile devices the checkbox turns into a “true” field as you can see in this image:
Is there a solution to fix this?

You can see this web page in: http://gestal.es/dev/muxia/actividades/escolas-deportivas/

I also have this problem with loading fonts from fontello. There appear square images. I updated my .htaccess to try to solve this problem, as I see in other post reply to allow CORS, but it doesn`t worked.
