Header is not stick from the top.

I have pushed the code, please verify and let me know if it's works.

@shweta MR only works if user is logged out. If user is logged-in and toolbar is vertical or closed, we can still see the gap above the header on scroll of page. Moving it to needs work.

@shweta__sharma
Remove top padding from style.css in MR.

.user-logged-in .sticky-top.navbar-dark {
        top: 0px;
    }

Looks Good to me Thanks for fixing that.
