**Cách 1:
# HTML:
<div class="back-to-top">
<img src="/themes/'.$ThemeSel.'/images/top.png">
</div>
# CSS:
.back-to-top {
bottom: 5em;
color: #000000;
cursor: pointer;
display: none;
font-size: 12px;
position: fixed;
right: 10px;
text-decoration: none;
z-index: 99999;
}
# JS:
<script>
jQuery(document).ready(function() {
var offset = 220;
var duration = 500;
jQuery(window).scroll(function() {
if (jQuery(this).scrollTop() > offset) {
jQuery('.back-to-top').fadeIn(duration);
} else {
jQuery('.back-to-top').fadeOut(duration);
}
if (jQuery(this).scrollTop() > 140) {
jQuery('.jack-moon-menu').fadeIn(140);
} else {
jQuery('.jack-moon-menu').fadeOut(0);
}
});
jQuery('.back-to-top').click(function(event) {
event.preventDefault();
jQuery('html, body').animate({scrollTop: 0}, duration);
return false;
});
});
</script>
**Cách 2:
# HTML:
<div id="hs-back-top" class="animated bounceInRight">
<i class="fa fa-angle-up"></i>
</div>
# JS:
<script type="text/javascript">
$(document).ready(function(a){
$(window).scroll(function() {
if ($(window).scrollTop() > 300) {
$('#hs-back-top').removeClass('bounceInRight bounceOutRight hs-hide').addClass('bounceInRight');
} else {
$('#hs-back-top').removeClass('bounceInRight bounceOutRight').addClass('bounceOutRight');
}
});
$('#hs-back-top').click(function() {
$('html,body').animate({
scrollTop: 0
}, 800);
});
});
