I am using bootstrap on my site and am having issues with the navbar fixed top. When I am just using the regular navbar, everything is fine. However, when i try to switch it

    I would do this:

    // add appropriate media query if required to target mobile nav only
.nav { overflow-y: hidden !important }

    This should make sure the nav block doesn't stretch downpage and covers the page content.

    I put this before the yield container:

    <div id="fix-for-navbar-fixed-top-spacing" style="height: 42px;">&nbsp;</div>

    I like this approach because it documents the hack needed to get it work, plus it also works for the mobile nav.

    EDIT - this works much better:

    @media (min-width: 980px) {
  body {
    padding-top: 60px;
    padding-bottom: 42px;
  }
}

    Just change fixed-top with sticky-top. this way you won't have to calculate the padding.
    And it works!!

    As others have stated adding a padding-top to body works great. But when you make the screen narrower (to cell phone widths) there is a gap between the navbar and the body. Also, a crowded navbar can wrap to a multi-line bar, overwriting some of the content again.

    This solved these kinds of issues for me

    body { padding-top: 40px; }
@media screen and (max-width: 768px) {
    body { padding-top: 0px; }
}

    This makes a 40px padding by default and 0px when under 768px width (which according to bootstrap's docs is the cell phone layout cutoff where the gap would be created)

    The solution for Bootstrap 4, it works perfect in all of my projects:

    change your first line from

    navbar-fixed-top

    to

    sticky-top

    Bootstrap documentation reference

    About time they did this right :D

    This issue is known and there's a workaround in the twitter bootstrap site:

    When you affix the navbar, remember to account for the hidden area underneath. Add 40px or more of padding to the <body>. Be sure to add this after the core Bootstrap CSS and before the optional responsive CSS.

    This worked for me:

    body { padding-top: 40px; }
