Well, first of all I want to thank you so much. I'm having a bit of an issue, however. It looks like my nav bar has gone above my header using this code and it bleeds into my posts when I scroll down. I haven't saved.
Is it possible to keep the header and nav bar's position fixed (like it is now) and have the content flow underneath -- so matter how far you scroll down the header and nav bar are always above the canvas and sidebars?
I can't tell you how much I appreciate your help.
