기본 제공되는 xedition기준으로

알고계시는 layout.html 그곳위에..

<!-- Blog -->
<a href="블로그주소" class="btn_blog">blog</a>
<!-- /Blog --> 추가

<!-- TOP -->
<a href="#" class="btn_top"><i class="xi-angle-up"><span class="blind">{$lang->cmd_move_up}</span></i></a>
<!-- /TOP -->

xedition/css/layout.css

.btn_top { display: none; position: fixed; right: 0; bottom: 57px; z-index: 1000; width: 48px; height: 48px; background-color: #555; font-size: 24px; color: #fff; text-align: center; opacity: 0.8; filter: alpha(opacity=80) } 밑에

.btn_blog { display: none; position: fixed; right: 0; bottom: 105px; z-index: 1000; width: 48px; height: 48px; background-color: #555; font-size: 24px; color: #fff; text-align: center; opacity: 0.8; filter: alpha(opacity=80) } 추가

xedition/js/layout.js에 붉은색 추가요..

// Scroll to top
        var scrollToTop = function() {
            var link = $('.btn_top');
            var link2 = $('.btn_blog');
            var windowW = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;

            $(window).scroll(function() {
                if (($(this).scrollTop() > 150) && (windowW > 1000)) {
                    link.fadeIn(100);
                    link2.fadeIn(100);
                } else {
                    link.fadeOut(100);
                    link2.fadeOut(100);
                }
            });
