    Hi, the subject tells it all: I need an additional class for the back to top button, but I can’t find the right place to add it. I use the snippet plugin also, so maybe some custom js will do the magic. Or directly into the themes’ php file (but where can I find the right place?).

    Any ideas? Thank you …

    Hi there,

    Try this PHP snippet:

    add_filter( 'generate_back_to_top_output', 'tu_custom_back_to_top_icon' );
    function tu_custom_back_to_top_icon() {
        printf(
    		'<a title="%1$s" rel="nofollow" href="#" class="generate-back-to-top CUSTOM-CLASS" style="opacity:0;visibility:hidden;" data-scroll-speed="%2$s" data-start-scroll="%3$s">
    				<span class="screen-reader-text">%5$s</span>
    				%6$s
    			</a>',
    			esc_attr__( 'Scroll back to top', 'generatepress' ),
    			absint( apply_filters( 'generate_back_to_top_scroll_speed', 400 ) ),
    			absint( apply_filters( 'generate_back_to_top_start_scroll', 300 ) ),
    			esc_attr( apply_filters( 'generate_back_to_top_icon', 'fa-angle-up' ) ),
    			esc_html__( 'Scroll back to top', 'generatepress' ),
    			generate_get_svg_icon( 'arrow' )
    	);
    }

    Let me know 🙂

    Hi Leo,

    thanks. The class is applied, but my wish behind all of it doesn’t take effect. I use the scroll to id plugin and want to let the back to top button run as smooth as my menu where I use the additional “ps2id” class to let the magic work. The class “ps2id” applied to the back to top doesn’t do anything…

    Hmm I don’t think that’s how it would work as our back to top script is still executing.

    If you want to use the script from another plugin, you’d basically need to create your own back to top button.

    Ok, I will do the button on my own. Thanks for helping …

    Hi Leo,

    well I made a little snippet on my own that’s working fine on a single file for itself (see below), but using hooks in generatepress to add this causes nothing but js errors (ReferenceError: Can’t find variable: $). Maybe I’m too stupid after quite a long week … any ideas?

    That’s my file:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
    <head>
    	<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
    	
    	<title>show onscroll</title>
    	<script src="http://code.jquery.com/jquery-latest.js"></script>
    	<script>
    	window.onscroll = function()
    	{
        if( window.XMLHttpRequest ) {
            if (document.documentElement.scrollTop > 150 || self.pageYOffset > 150) {
                $('#btt').fadeIn();
            } else if (document.documentElement.scrollTop < 150 || self.pageYOffset < 150) {
                $('#btt').fadeOut();
            }
        }
    }
    </script>
    	<style type="text/css">
    
    a#btt {
    	background-color: #000;
    	display: none;
    	padding: 8px 14px 8px 14px;
    	border-radius: 3px;
    	color: #FFF;
    	position: fixed;
    	z-index: 10;
    	right: 30px;
    	bottom: 80px;
    	opacity: 0.38;
    	font-size: 14px;
    	
    }
    a#btt:hover {
      opacity: 0.4;
    }
    
    body {
      min-height: 2000px;
    }
    </style>
    </head>
    <body>
    	<p>scroll down</p>
    	<a href="#" id="btt">to top</a>
    
    	</body>
    </html>

    Hmm I’m not familiar with JS but I don’t think hooks should be used for that though.
