2 issues with the page-menu (page-submenu.html)

**1. **
When I view my page in mobile version, the page submenu (div id=”page-menu”) in open state has the original background color, it does not get changed by changing colors via the colors.css file.

2.
The #page-menu’s “current” class doesn’t seem to get transferred to the actually active item from the default first active. I tried to include some other js files, thinking perhaps the function was coded in one of those, but nothing seemed to trigger this behavior. Please help me out how to solve this. Thanks.

The 1st issue is resolved, the 2nd still doesn't work.
