bootstrap left nav overlap on mobile device

I am EXTREMELY new to bootstrap.  I found code for a fixed left nav that works awesome on a desktop and laptop, but on a mobile device the body overlaps the left nav.  Any suggestions:

Post the real HTML not the encoded HTML or better yet a link to the page.

Anything that is fixed position is outside the natural page flow and the affix class isn't meant for use in the way you want.

If you want the fixed sidebar you will have to use some media queries to set the width.
This is just a default of 25% which would need increasing on very small screens

.sidebar-fixed {
