Mobile Menu Button Not Working

Soooo I created my first child theme using the twenty twelve…

I obviously messed up my code somewhere… the site seems to function perfectly on a laptop, but three things are lost on my mobile:

1) the menu button does not work. when you click on it nothing happens.

2) the styling of my dropshadow/ borders on the scrambledgregs.com/blog page are gone (and all category pages)

3) the tagline font is no longer styled.

Can anyone help?
