Dear Azam,
now it’s better but unfortunately there’s always a problem.
Please see the screenshot (my site – your demo) to better understand.

There is a glitch over the pics and footer is not showed (maybe I’ve to create it)

Dear Azam,
I think problem is in Chrome. I’ve seen site from Safari and problems are not visible.
Please navigate site from chrome and see the problems:
Hamburger menu doesn’t go
White glitch over the photos
Text (Twitter-Instagram) in strange position
