Mobile menu in theme shelf doesn't have any background color on android
I am developing a site for a client. I normally develop templates from scratch, but in this case, I used a Yootheme template mostly for the quick mobile version from warp 6. Now the site is going great. Widgetkit rocks. But when I turned mobile on and checked it on my phone, I notices the menu was nowhere to be seen, it was hidden in the 'list' icon. Don't know, but maybe that is the way sites are doing it now a days.
The issue comes when I click the mobile menu icon, and the items show. They, however, have no background color applied to them, so when they hover over the content is looks awful.
I don't have to go into the CSS and manually add that, do I?
