I found this simple responsive mobile menu at: www . responsivemobilemenu . com that works perfect for my needs but I need/want it to display at 100% browser width with no space to the left and right side when viewed in a mobile browser, i.e. Android, iPhone. I tried editing the CSS but no luck. I'm figuring it's something other than a simple padding adjustment. Would greatly appreciate any help.

Here is a demo you can view with your mobile phone:

Here is a link to the CSS file:
www . mflyer . org/css/responsivemobilemenu . css

Note: If it helps any I also included the associated js file in the css folder.
