In the media query, you'll have to specify margin-right:0 for your .col2.  It's still applying it from the css above.

Try this:

You're right, I forgot I didn't take that out. When you're learning something new you never know if you're making a stupid little mistake or totally off base. You're lucky, I wasn't going to give so many points but somehow in IE9 I couldn't change the slider! Thanks for your help
