Styling with CSS
.box-fixed {
position: fixed;
bottom: 10px;
right: 10px;
}
Using JavaScript
if ($('#mydiv').offset().top() + $('#mydiv').height() > $(document).height()) {
$('#mydiv').addClass('box-fixed');
}
Check out this handy jsFiddle demonstration that I have utilized in the past.
Using jQuery:
var stickerTop = parseInt($('#sticker').offset().top);
$(window).scroll(function() {
$("#sticker").css((parseInt($(window).scrollTop()) + parseInt($("#sticker").css('margin-top')) > stickerTop) ? {
position: 'fixed',
top: '0px'
} : {
position: 'relative'
});
});
JavaScript Code
const initialPosition = $('#toolbar').offset().top;
$(window).scroll(function() {
if ( $('#toolbar').offset().top - $(window).scrollTop() < 0 ) $('#toolbar').addClass('fixed');
if ( $(window).scrollTop() < initialPosition ) $('#toolbar').removeClass('fixed');
});
