How can I make a div stick to the top of the screen once it s been scrolled to

Question

I would like to create a div  that is situated beneath a block of content but that once the page has been scrolled enough to contact its top boundary  becomes fixed in place and scrolls with the page

User · Answer

I have links setup in a div so it is a vertical list of letter and number links.

#links {
    float:left;
    font-size:9pt;
    margin-left:0.5em;
    margin-right:1em;
    position:fixed;
    text-align:center;
    width:0.8em;
}

I then setup this handy jQuery function to save the loaded position and then change the position to fixed when scrolling beyond that position.

NOTE: this only works if the links are visible on page load!!

var listposition=false;
jQuery(function(){
     try{
        ///// stick the list links to top of page when scrolling
        listposition = jQuery('#links').css({'position': 'static', 'top': '0px'}).position();
        console.log(listposition);
        $(window).scroll(function(e){
            $top = $(this).scrollTop();
            $el = jQuery('#links');
            //if(typeof(console)!='undefined'){
            //    console.log(listposition.top,$top);
            //}
            if ($top > listposition.top && $el.css('position') != 'fixed'){
                $el.css({'position': 'fixed', 'top': '0px'});
            }
            else if ($top < listposition.top && $el.css('position') == 'fixed'){
                $el.css({'position': 'static'});
            }
        });

    } catch(e) {
        alert('Please vendor [email protected] (Myvendor JavaScript Issue)');
    }
});

And here s how without jquery  UPDATE  see other answers where you can now do this with CSS only    x000D   x000D  var startProductBarPos -1  x000D  window onscroll function    x000D    var bar   document getElementById  nav    x000D    if startProductBarPos lt 0 startProductBarPos findPosY bar   x000D   x000D    if pageYOffset gt startProductBarPos   x000D      bar style position  fixed   x000D      bar style top 0  x000D     else  x000D      bar style position  relative   x000D      x000D   x000D     x000D   x000D  function findPosY obj    x000D    var curtop   0  x000D    if  typeof  obj offsetParent      undefined   amp  amp  obj offsetParent    x000D      while  obj offsetParent    x000D        curtop    obj offsetTop  x000D        obj   obj offsetParent  x000D        x000D      curtop    obj offsetTop  x000D      x000D    else if  obj y  x000D      curtop    obj y  x000D    return curtop  x000D    x000D     margin 0 padding 0   x000D   nav   x000D    border  1px red dashed  x000D    background   00ffff  x000D    text-align center  x000D    padding  21px 0  x000D   x000D    margin  0 auto  x000D    z-index 10   x000D    width 100   x000D    left 0  x000D    right 0  x000D    x000D   x000D   header   x000D    text-align center  x000D    padding  65px 0  x000D    border  1px red dashed  x000D    x000D   x000D   content   x000D    padding  500px 0  x000D    text-align center  x000D    border  1px red dashed  x000D    x000D   footer   x000D    padding  100px 0  x000D    text-align center  x000D    background   777  x000D    border  1px red dashed  x000D    x000D   lt header class  header  gt This is a Header lt  header gt  x000D   lt div id  nav  class  nav  gt Main Navigation lt  div gt  x000D   lt div class  content  gt Hello World  lt  div gt  x000D   lt footer class  footer  gt This is a Footer lt  footer gt  x000D   x000D   x000D

As Josh Lee and Colin  t Hart have said  you could optionally just use position  sticky  top  0  applying to the div that you want the scrolling at     Plus  the only thing you will have to do is copy this into the top of your page or format it to fit into an external CSS sheet    lt style gt   sticky div s name here   position  sticky  top  0     lt  style gt    Just replace  sticky div s name here with the name of your div  i e  if your div was  lt div id  example  gt  you would put  example   position  sticky  top  0

As of January 2017 and the release of Chrome 56  most browsers in common use support the position  sticky property in CSS    thing to stick     position  sticky    top  0px      does the trick for me in Firefox and Chrome   In Safari you still need to use position  -webkit-sticky   Polyfills are available for Internet Explorer and Edge  https   github com wilddeer stickyfill seems to be a good one

The accepted answer works but doesn t move back to previous position if you scroll above it  It is always stuck to the top after being placed there       window  scroll function e         el       fixedElement        if    this  scrollTop    gt  42  amp  amp   el css  position       fixed               fixedElement   css   position    fixed    top    0px           else if    this  scrollTop    lt  42  amp  amp   el css  position       relative               fixedElement   css   relative    fixed    top    42px      this was just my previous position formating               jleedev s response whould work  but I wasn t able to get it to work  His example page also didn t work  for me

You ve seen this example on Google Code s issue page and  only recently  on Stack Overflow s edit page   CMS s answer doesn t revert the positioning when you scroll back up  Here s the shamelessly stolen code from Stack Overflow   function moveScroller         var  anchor       scroller-anchor        var  scroller       scroller         var move   function             var st     window  scrollTop            var ot    anchor offset   top          if st  gt  ot                 scroller css                   position   fixed                   top   0px                            else                scroller css                   position   relative                   top                                            window  scroll move       move           lt div id  sidebar  style  width 270px   gt      lt div id  scroller-anchor  gt  lt  div gt      lt div id  scroller  style  margin-top 10px  width 270px  gt       Scroller Scroller Scroller    lt  div gt   lt  div gt    lt script type  text javascript  gt       function         moveScroller           lt  script gt     And a simple live demo   A nascent  script-free alternative is position  sticky  which is supported in Chrome  Firefox  and Safari  See the article on HTML5Rocks and demo  and Mozilla docs

You can add 3 extra rows so when the user scroll back to the top  the div will stick on its old place   Here is the code   if    this  scrollTop    lt  200  amp  amp   el css  position       fixed            fixedElement   css   position    relative    top    200px

User · Answer

You could use simply css  positioning your element as fixed    fixedElement       background-color   c0c0c0      position fixed      top 0      width 100       z-index 100      Edit  You should have the element with position absolute  once the scroll offset has reached the element  it should be changed to fixed  and the top position should be set to zero   You can detect the top scroll offset of the document with the scrollTop function     window  scroll function e      var  el       fixedElement       var isPositionFixed     el css  position       fixed      if    this  scrollTop    gt  200  amp  amp   isPositionFixed         el css   position    fixed    top    0px            if    this  scrollTop    lt  200  amp  amp  isPositionFixed        el css   position    static    top    0px                 When the scroll offset reached 200  the element will stick to the top of the browser window  because is placed as fixed

I had the same problem as you and ended up making a jQuery plugin to take care of it  It actually solves all the problems people have listed here  plus it adds a couple of optional features too   Options  stickyPanelSettings            Use this to set the top margin of the detached panel      topPadding  0          This class is applied when the panel detaches      afterDetachCSSClass              When set to true the space where the panel was is kept open      savePanelSpace  false          Event fires when panel is detached        function detachedPanel  panelSpacer            onDetached  null          Event fires when panel is reattached        function detachedPanel            onReAttached  null          Set this using any valid jquery selector to         set the parent of the sticky panel         If set to null then the window object will be used      parentSelector  null      https   github com donnyv sticky-panel  demo  http   htmlpreview github io  https   github com donnyv sticky-panel blob master jquery stickyPanel Main htm

Here is an extended version to Josh Lee s answer  If you want the div to be on sidebar to the right  and float within a range  i e   you need to specify top and bottom anchor positions   It also fixes a bug when you view this on mobile devices  you need to check left scroll position otherwise the div will move off screen    function moveScroller         var move   function             var st     window  scrollTop            var sl     window  scrollLeft            var ot       scroller-anchor-top   offset   top          var ol       scroller-anchor-top   offset   left          var bt       scroller-anchor-bottom   offset   top          var s       scroller            if st  gt  ot                if  st  lt  bt - 280    280px is the approx  height for the sticky div                               s css                       position   fixed                       top   0px                       left  ol-sl                                                else                               s css                       position   fixed                       top  bt-st-280                      left  ol-sl                                              else               s css                   position   relative                   top                      left                                             window  scroll move       move

Here is another option   JAVASCRIPT  var initTopPosition      myElementToStick   offset   top       window  scroll function        if   window  scrollTop    gt  initTopPosition              myElementToStick   css   position   fixed   top   0px         else             myElementToStick   css   position   absolute   top  initTopPosition  px           Your  myElementToStick should start with position absolute CSS property

The info provided to answer this other question may be of help to you  Evan   Check if element is visible after scrolling  You basically want to modify the style of the element to set it to fixed only after having verified that the document body scrollTop value is equal to or greater than the top of your element
