CSS removing padding

Can someone please help me figure out how to remove this white line on the right side of my content? I think it is padding, but I’m not sure where to find it in the css to fix it.

Also, how can I remove the white spaces between the subhead and the options?

Any help is greatly appreciated!

Thank you!
