I have implemented a back to top button using the following resource:
Although the button is functioning as expected, I am encountering an issue with the hover effect. In Chrome inspector, manually forcing hover on .cd-top does not apply the CSS style as intended. The opacity remains unchanged upon hovering.
.no-touch .cd-top:hover {
/*background-color: #FF9E00;*/
opacity: 1;
}
You can see the page where this issue is occurring here
Here is the JavaScript code:
/***************************************************
SCROLL FOR PORTFOLIO
***************************************************/
jQuery(document).ready(function($){
// browser window scroll (in pixels) after which the "back to top" link is shown
var offset = 300,
//browser window scroll (in pixels) after which the "back to top" link opacity is reduced
offset_opacity = 1200,
//duration of the top scrolling animation (in ms)
scroll_top_duration = 700,
//grab the "back to top" link
$back_to_top = $('.cd-top');
//hide or show the "back to top" link
$(window).scroll(function(){
( $(this).scrollTop() > offset ) ? $back_to_top.addClass('cd-is-visible') : $back_to_top.removeClass('cd-is-visible cd-fade-out');
if( $(this).scrollTop() > offset_opacity ) {
$back_to_top.addClass('cd-fade-out');
}
});
//smooth scroll to top
$back_to_top.on('click', function(event){
event.preventDefault();
$('body,html').animate({
scrollTop: 0 ,
}, scroll_top_duration
);
});
});
Here is the full CSS code:

}
.cd-top.cd-is-visible {
/* the button becomes visible */
visibility: visible;
opacity: 1;
}
.cd-top.cd-fade-out {
/* if the user keeps scrolling down, the button is out of focus and becomes less visible */
opacity: .5;
}
.no-touch .cd-top:hover {
/*background-color: #FF9E00;*/
opacity: 1;
}
@media only screen and (min-width: 768px) {
