How to make div switch to bottom fixed after you scroll to that div?

Question

Good day everyone. I am trying to switch my div into a fixed one at the bottom when it appears on screen when both scrolling up and down.

I found this stack overflow topic which does the thing I'm attepting to do but at top HERE.

Code:

var fixmeTop = $('.fixme').offset().top;       // get initial position of the element

$(window).scroll(function() {                  // assign scroll event listener

    var currentScroll = $(window).scrollTop(); // get current position

    if (currentScroll >= fixmeTop) {           // apply position: fixed if you
        $('.fixme').css({                      // scroll to that element or below it
            position: 'fixed',
            top: '0',
            left: '0'
        });
    } else {                                   // apply position: static
        $('.fixme').css({                      // if you scroll above it
            position: 'static'
        });
    }

});

After many try and many articles red, I just can't manage to tweak it to be fixed at the bottom (kind of new to javascript). So I am please asking for your help.

Hey you can do it like this

const heightOfText = 15
if (currentScroll >= fixmeTop - $(window).height() + heightOfText) {
   $('.fixme').css({
       position: 'fixed',
       bottom: '0',
       left: '0'
   });
}

So when you see your .fixme at the bottom of the text it attaches to the bottom with bottom: '0' . Let me know if it helps.

You could use position: sticky

 /*QuickReset*/ *{margin:0;box-sizing:border-box;}.content { min-height: 200vh; border: 4px dashed #000; }.sticky-bottom { position: sticky; bottom: 0; padding: 2em 0; background: #0bf; }

 <div> <div class="content"> 1. Lorem ut florem... </div> </div> <div> <div class="content"> 2. Lorem ut florem... </div> <div class="sticky-bottom">Stick me when in viewport</div> </div>
