How to make bootstrap affix inside iFrame?

Question

css

Made a floating nav-bar using bootstrap affix . If the page is loaded directly, everything is ok, but when loaded inside the iFrame, the nav-bar simply stretches to its full height and does not move.
I tried to bind offset to window.parent, as written here , but it didn't help (mb did something wrong).
Any suggestions?

Here's what I came up with:
on the window.onscroll event, a function is called that changes the nav-bar's margin. Everything is smoothed out with a webkit. Yes, a crutch
