Bootstrap CSS messes up collapsible menu z-index?-Twitter bootstrap

Basically, I have a site that has a sticky header and sidebar nav but when the screen is made smaller, the menu adopts a hamburger button that can expand the collapsible sidebar.

This works as expected except for one thing: The inclusion of the bootstrap CSS cdn.

So If I comment out the CDN for the bootstrap CSS it works correctly, but If I include it and make the screen mobile size, upon hitting the menu button, the menu expands under the main content cards in the main div. If I comment it out, the menu expands on top of the cards as it should.

IN my codepen above, it has the bootstrap CDN to show the error. I have a custom CSS which is also attached there and I have a lot of styling there, I’m just wondering how I can get this fixed and still have the bootstrap CSS for other stying.

nav.open {z-index: 1 !important};

Z-index will allow you to show the nav on top of other elements and the !important will help you overwrite the bootstrap css
