handsome:自定义输出body 尾部的HTML代码
其他：插入到<\/body>之前

<script>    // 鼠标点击爱心特效
    !function (e, t, a) {
        function r() {
            for (var e = 0; e < s.length; e++) {
                s[e].alpha <= 0 ? (t.body.removeChild(s[e].el), s.splice(e, 1)) : (s[e].y--, s[e].scale += .004, s[e].alpha -= .013, s[e].el.style.cssText = "left:" + s[e].x + "px;top:" + s[e].y + "px;opacity:" + s[e].alpha + ";transform:scale(" + s[e].scale + "," + s[e].scale + ") rotate(45deg);background:" + s[e].color + ";z-index:99999");
            }
            requestAnimationFrame(r)
        }

        function n() {
            var t = "function" == typeof e.onclick && e.onclick;
            e.onclick = function (e) {
                t && t(),
                    o(e)
            }
        }

        function o(e) {
            var a = t.createElement("div");
            a.className = "heart",
                s.push({
                    el: a,
                    x: e.clientX - 5,
                    y: e.clientY - 5,
                    scale: 1,
                    alpha: 1,
                    color: c()
                }),
                t.body.appendChild(a)
        }

        function i(e) {
            var a = t.createElement("style");
            a.type = "text/css";
            try {
                a.appendChild(t.createTextNode(e))
            } catch (t) {
                a.styleSheet.cssText = e
            }
            t.getElementsByTagName("head")[0].appendChild(a)
        }

        function c() {
            return "rgb(" + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + ")"
        }

        var s = [];
        e.requestAnimationFrame = e.requestAnimationFrame || e.webkitRequestAnimationFrame || e.mozRequestAnimationFrame || e.oRequestAnimationFrame || e.msRequestAnimationFrame ||
            function (e) {
                setTimeout(e, 1e3 / 60)
            },
            i(".heart{width: 10px;height: 10px;position: fixed;background: #f00;transform: rotate(45deg);-webkit-transform: rotate(45deg);-moz-transform: rotate(45deg);}.heart:after,.heart:before{content: '';width: inherit;height: inherit;background: inherit;border-radius: 50%;-webkit-border-radius: 50%;-moz-border-radius: 50%;position: fixed;}.heart:after{top: -5px;}.heart:before{left: -5px;}"),
            n(),
            r()
    }(window, document);</script>
<script>$("body").css("cursor", "url('https://123.png'), default");
    $("a").css("cursor", "url('https://123.png'), pointer");</script>
<script>console.log('https://your.web.com', 'line-height:28px;padding:4px;background:#3f51b5;color:#fff;font-size:14px;', 'padding:4px; color:#673ab7');</script>

最后三行是设置鼠标图标，需要自己修改图片链接。
修改鼠标图标以后，貌似鼠标会有点闪烁，不推荐修改鼠标图标。
