I ve just solved this problem on a site I m working on  and thought I would share it in the hope it helps someone   My solution takes the distance from the footer to the top of the page - if the user has scrolled further than this  it pulls the sidebar back up with a negative margin     window  scroll      gt          Distance from top of document to top of footer    topOfFooter       footer   position   top       Distance user has scrolled from top  adjusted to take in height of sidebar  570 pixels inc  padding     scrollDistanceFromTopOfDoc     document  scrollTop     570       Difference between the two    scrollDistanceFromTopOfFooter   scrollDistanceFromTopOfDoc - topOfFooter        If user has scrolled further than footer       pull sidebar up using a negative margin    if  scrollDistanceFromTopOfDoc  gt  topOfFooter            cart   css  margin-top    0 - scrollDistanceFromTopOfFooter       else            cart   css  margin-top   0

I ran into this same issue recently  posted the my solution also here  Preventing element from displaying on top of footer when using position fixed  You can achieve a solution leveraging the position property of the element with jQuery  switching between the default value  static for divs   fixed and absolute  You will also need a container element for your fixed element  Finally  in order to prevent the fixed element to go over the footer  this container element can t be the parent of the footer   The javascript part involves calculating the distance in pixels between your fixed element and the top of the document  and comparing it with the current vertical position of the scrollbar relatively to the window object  i e  the number of pixels above that are hidden from the visible area of the page  every time the user scrolls the page  When  on scrolling down  the fixed element is about to disappear above  we change its position to fixed and stick on top of the page    This causes the fixed element to go over the footer when we scroll to the bottom  especially if the browser window is small  Therefore  we will calculate the distance in pixels of the footer from the top of the document and compare it with the height of the fixed element plus the vertical position of the scrollbar  when the fixed element is about to go over the footer  we will change its position to absolute and stick at the bottom  just over the footer   Here s a generic example   The HTML structure    lt div id  content  gt       lt div id  leftcolumn  gt           lt div class  fixed-element  gt              This is fixed           lt  div gt       lt  div gt       lt div id  rightcolumn  gt Main content here lt  div gt       lt div id  footer  gt  The footer  lt  div gt   lt  div gt      The CSS    leftcolumn       position  relative     fixed-element       width  180px     fixed-element fixed       position  fixed      top  20px     fixed-element bottom       position  absolute      bottom  356px     Height of the footer element  plus some extra pixels if needed        The JS      Position of fixed element from top of the document var fixedElementOffset       fixed-element   offset   top     Position of footer element from top of the document     You can add extra distance from the bottom if needed     must match with the bottom property in CSS var footerOffset       footer   offset   top - 36   var fixedElementHeight       fixed-element   height         Check every time the user scrolls   window  scroll function  event            Y position of the vertical scrollbar     var y     this  scrollTop         if   y  gt   fixedElementOffset  amp  amp    y   fixedElementHeight    lt  footerOffset                 fixed-element   addClass  fixed                fixed-element   removeClass  bottom                        else if   y  gt   fixedElementOffset  amp  amp    y   fixedElementHeight    gt   footerOffset                 fixed-element   removeClass  fixed                           fixed-element   addClass  bottom              else               fixed-element   removeClass  fixed bottom

I ve made some changes to the second most popular answer as i found this worked better for me  The changes use window innerHeight as it is more dynamic than adding your own height for the nav  above used   570   this allows the code to work on mobile  tablet and desktop dynamicly      window  scroll      gt                  Distance from top fo document to top of footer             topOfFooter       footer   position   top                  Distance user has scrolled from top   windows inner height              scrollDistanceFromTopOfDoc     document  scrollTop     window innerHeight                  Difference between the two               scrollDistanceFromTopOfFooter   scrollDistanceFromTopOfDoc - topOfFooter                  If user has scrolled further than footer                if  scrollDistanceFromTopOfDoc  gt  topOfFooter                       add margin-bottom so button stays above footer                      floating-button   css  margin-bottom    0   scrollDistanceFromTopOfFooter                   else                       remove margin-bottom so button goes back to the bottom of the page                     floating-button   css  margin-bottom   0

If your elements are glitching this is probably because when you change the position to relative the Y position of the footer increases which tries to send the item back to fixed which creates a loop  You can avoid this by setting two different cases when scrolling up and down  You don t even need to reference the fixed element  just the footer  and window size  const footer   document querySelector  footer    document addEventListener  quot scroll quot   checkScroll    let prevY   window scrollY   window innerHeight  function checkScroll       let footerTop   getRectTop footer    window scrollY    let windowBottomY   window scrollY   window innerHeight    if  prevY  lt  windowBottomY        Scroll Down     if  windowBottomY  gt  footerTop        setScrolledToFooter true     using React state  Change class or change style in JS      else      Scroll Up     if  windowBottomY  lt   footerTop        setScrolledToFooter false        prevY   windowBottomY     function getRectTop el      var rect   el getBoundingClientRect      return rect top     and the position of the element in the style object as follows  position  scrolledToFooter    relative     fixed
