Sticking footer to the bottom

Contribute UX

I assume you’re talking about a custom footer added in the admin>customize section. It seems that the only way to do it on a Discourse forum is with javascript. This mostly works, but it would be great if someone could correct the way I am firing the javascript function. The way it’s being done here can’t be very efficient.

Edit: this is an improved version. Unless someone suggests a more obvious way to do this, I’ll make this into a plugin.

given this as a footer:

<div id="sticky-footer">
    <div class="wrap">
        <h3>this is the custom footer</h3>  
    </div>
</div>

#sticky-footer {
    position: static;
    color: #fff;
    background: #CD5C5C;
    // In case the window with a static footer is resized downwards
    box-shadow: 0 300px 0 300px #CD5C5C;
    height: 120px;
}

This will fix it to the bottom when there isn’t enough content to push it there.

<script>
    var stickFooter = function() {
        var $footer = $('#sticky-footer'),
            footerHeight = $footer.outerHeight(),
            footerOffset = $footer.offset(),
            footerBottom;
            
            if (footerOffset) {
                footerBottom = footerHeight + footerOffset.top;

                if (footerBottom <= $(window).height()) {
                    $footer.css({
                        'position': 'fixed',
                        'left': 0,
                        'right': 0,
                        'bottom': 0
                    });
                    // In case the window is resized upwards
                    $('#main').css('padding-bottom', footerHeight + "px");
                } else {
                    $footer.css('position', 'static');
                    $('#main').css('padding-bottom', 0);
                }
            }
    };
