            p.space It's simple, jus drop this JavaScript in your HTML:
            ul.code.space
                li.code__line document.body.addEventListener("mousemove", function(event) {
                li.code__line.code__push1 moveCursor(event);

                li.code__line.space var svgCursor = document.getElementById('svg-cursor');
                li.code__line function moveCursor(e) {
                li.code__line.code__push1 var x = e.clientX - 5,
                li.code__line.code__push3.space y = e.clientY - 5;
                li.code__line.code__push1.space svgCursor.setAttribute('style', 'left: ' + x + 'px; top: ' + y + 'px');
                li.code__line.code__push1 if (e.target.className.indexOf('custom-cursor') > -1) {

                li.code__line.code__push8 svgCursor.setAttribute('class', 'svg-cursor svg-cursor__action')
                li.code__line.code__push8 break;

                li.code__line.code__push8 break;
                li.code__line.code__push3 }
