How to snap the menu to the top when scrolling the page?

Question

css

I want the menu to remain visible when scrolling down the page, and not go up

Please help =) If there is some class in the bootstrap or via css somehow? I will be very grateful =)
PS Thank you!

Answer 1

Is this your first freelancing assignment?
Tryposition: fixed;

Answer 2

For example, a menu (.top-navbar) 50px high glued to the screen:

.top-navbar{
position: fixed;
z-index: 10;
top: 0;
left: 0;
right 0:
width: 100%;
height: 50px;
}

More correct for your case (on bootstrap):

<nav class="navbar navbar-default navbar-fixed-top" role="navigation" data-spy="affix" data-offset-top="50">
  <div class="container">
    ...
  </div>
</nav>

Will need to work with .affix in CSS
