I have back-to-top script with an arrow icon which appears when scrolling down and disappears when the page content is on top. Works perfect, but when I insert the script in Wordpress the scrollTop part of the script works but not the fade-in and fade-out effect.

Any solution?

(function($) {

$('body').prepend('<a href="#" class="back-to-top">Back to Top</a>');
var amountScrolled = 300;
$(window).scroll(function() {
if ( $(window).scrollTop() > amountScrolled ) {
    $('a.back-to-top').fadeIn('slow');
} else {
    $('a.back-to-top').fadeOut('slow');
}
});

$('a.back-to-top, a.simple-back-to-top').click(function() {
$('html, body').animate({
    scrollTop: 0
}, 700);
return false;
});

}(jQuery));

body {background:#FEF1D4; height:1000px}

.back-to-top {
    display: none;
    width: 4.75rem;
    height: 4.75rem;
    text-indent: -9999px;
    position: fixed;
    z-index: 1500;
    left: 0.5rem;
    bottom: 1rem;
    background: url(.png) no-repeat center 43%;
    background-size: contain;
}

<script src=".3.1/jquery.min.js"></script>

Expected result → jsfiddle
