You could use position  sticky   navbar     position  sticky    top  0px      The  navbar should be a direct child of the body though

This worked great for me  Don t forget to put a filler div in there where the navigation bar used to be  or else the content will jump every time it s fixed unfixed   function setSkrollr        var objDistance    navbar offset   top        window  scroll function             var myDistance     window  scrollTop            if  myDistance  gt  objDistance                navbar addClass  navbar-fixed-top                      if  objDistance  gt  myDistance                navbar removeClass  navbar-fixed-top

Note  2015   Both question and the answer below apply to the old  deprecated version 2 x of Twitter Bootstrap   This feature of making and element  sticky  is built into the Twitter s Bootstrap and it is called Affix  All you have to do is to add    lt div data-spy  affix  data-offset-top  121  gt        your navbar      lt  div gt    around your tag and do not forget to load the Bootstrap s JS files as described in the manual  Data attribute offset-top tells how many pixels the page is scrolled  from the top  to fix you menu component  Usually it is just the space to the top of the page   Note  You will have to take care of the missing space when the menu will be fixed  Fixing means cutting it off out of your page layer and pasting in different layer that does not scroll  I am doing the following    lt div style  height  77px   gt     lt div data-spy  affix  data-offset-top  121  gt       lt div style  position  relative  height  0  width  100    gt         lt div style  position  absolute  top  0  left  0   gt              my menu            lt  div gt       lt  div gt     lt  div gt   lt  div gt    where 77px is the height of my affixed component

For Bootstrap 4  a new class was released for this  According to the utilties docs   Apply the class sticky-top    lt div class  sticky-top  gt     lt  div gt    For further navbar position options  visit here  Also  keep in mind that position  sticky  is not supported in every browser so this may not be the best solution for you if you need to support older browsers

In answer to Shubham Patwa  This way  the page is  jumpy  soon as the class  navbar-fixed-top  applies  That s because the  mainnav is throwen in and out of the document s DOM flow  This can result in an ugly UX if the page has a  critical height   jumping between fixed and un-fixed  mainnav position   I altered the code this way  which seems to work fine  not pixel-perfect  but fine      document  ready function       var navpos       mainnav   offset      var navheight       mainnav   outerHeight       window  bind  scroll   function       if    window  scrollTop    gt  navpos top           mainnav   addClass  navbar-fixed-top          body   css  marginTop  navheight           else            mainnav   removeClass  navbar-fixed-top            body   css  marginTop   0
