hi,

I am experiencing elements position misbehaviour into my page, in IE(11) only; The logotext, the menu and the left sidebar text, remain in place doesn't move with the `wrapper` when the left slider is open (clicking on info+ button). I've read about position : fixed + transition in IE problems.

I've tried to apply `(fixed);` to the `header` but something went wrong and the `wrapper` receive a brake-movement at open/closing slider. (The sidebar didn't work with `(fixed);`)

Also I've tried to tweak the `css` modifying the element position values in `static/ absolute` but without succees. Tests are made in full screen, the site is not for mobile screens.

The fixed header does not seem to be honoring the containing block of the relative positioned div that is its immediate ancestor. I can provide a live link but I am unable to do that at this moment not so sure why; if this help, try searching on ggl "Fixed position misbehaviour in IE11" and u'll find a stackoverflow page with the above described subject plus links. How can I approach this, is this an IE bug?

Thanks,
