自定义icarus主题的配置，使个人博客看起来很舒服。

雪花特效

在/themes/icarus/source/js/目录下新建一个src目录，在src目录中新建snow.js文件，
把下面的代码写到snow.js文件中

function snowFall(snow) {
    /* 可配置属性 */
    snow = snow || {};
    this.maxFlake = snow.maxFlake || 200;   /* 最多片数 */
    this.flakeSize = snow.flakeSize || 10;  /* 雪花形状 */
    this.fallSpeed = snow.fallSpeed || 1;   /* 坠落速度 */
}
/* 兼容写法 */
requestAnimationFrame = window.requestAnimationFrame ||
    window.mozRequestAnimationFrame ||
    window.webkitRequestAnimationFrame ||
    window.msRequestAnimationFrame ||
    window.oRequestAnimationFrame ||
    function(callback) { setTimeout(callback, 1000 / 60); };

cancelAnimationFrame = window.cancelAnimationFrame ||
    window.mozCancelAnimationFrame ||
    window.webkitCancelAnimationFrame ||
    window.msCancelAnimationFrame ||
	window.oCancelAnimationFrame;
/* 开始下雪 */
snowFall.prototype.start = function(){
    /* 创建画布 */
    snowCanvas.apply(this);
    /* 创建雪花形状 */
    createFlakes.apply(this);
    /* 画雪 */
    drawSnow.apply(this)
}
/* 创建画布 */
function snowCanvas() {
    /* 添加Dom结点 */
    var snowcanvas = document.createElement("canvas");
    snowcanvas.id = "snowfall";
    snowcanvas.width = window.innerWidth;
    snowcanvas.height = document.body.clientHeight;
    snowcanvas.setAttribute("style", "position:absolute; top: 0; left: 0; z-index: 1; pointer-events: none;");
    document.getElementsByTagName("body")[0].appendChild(snowcanvas);
    this.canvas = snowcanvas;
    this.ctx = snowcanvas.getContext("2d");
    /* 窗口大小改变的处理 */
    window.onresize = function() {
        snowcanvas.width = window.innerWidth;
        /* snowcanvas.height = window.innerHeight */
    }
}
/* 雪运动对象 */
function flakeMove(canvasWidth, canvasHeight, flakeSize, fallSpeed) {
    this.x = Math.floor(Math.random() * canvasWidth);   /* x坐标 */
    this.y = Math.floor(Math.random() * canvasHeight);  /* y坐标 */
    this.size = Math.random() * flakeSize + 2;          /* 形状 */
    this.maxSize = flakeSize;                           /* 最大形状 */
    this.speed = Math.random() * 1 + fallSpeed;         /* 坠落速度 */
    this.fallSpeed = fallSpeed;                         /* 坠落速度 */
    this.velY = this.speed;                             /* Y方向速度 */
    this.velX = 0;                                      /* X方向速度 */
    this.stepSize = Math.random() / 30;                 /* 步长 */
    this.step = 0                                       /* 步数 */
}
flakeMove.prototype.update = function() {
    var x = this.x,
        y = this.y;
    /* 左右摆动(余弦) */
    this.velX *= 0.98;
    if (this.velY <= this.speed) {
        this.velY = this.speed
    }
    this.velX += Math.cos(this.step += .05) * this.stepSize;

    this.y += this.velY;
    this.x += this.velX;
    /* 飞出边界的处理 */
    if (this.x >= canvas.width || this.x <= 0 || this.y >= canvas.height || this.y <= 0) {
        this.reset(canvas.width, canvas.height)
    }
};
/* 飞出边界-放置最顶端继续坠落 */
flakeMove.prototype.reset = function(width, height) {
    this.x = Math.floor(Math.random() * width);
    this.y = 0;
    this.size = Math.random() * this.maxSize + 2;
    this.speed = Math.random() * 1 + this.fallSpeed;
    this.velY = this.speed;
    this.velX = 0;
};
// 渲染雪花-随机形状（此处可修改雪花颜色！！！）
flakeMove.prototype.render = function(ctx) {
    var snowFlake = ctx.createRadialGradient(this.x, this.y, 0, this.x, this.y, this.size);
    snowFlake.addColorStop(0, "rgba(255, 255, 255, 0.9)");  /* 此处是雪花RGB颜色，默认是白色 */
    snowFlake.addColorStop(.5, "rgba(255, 255, 255, 0.5)"); /* 若要改为其他颜色，请自行查 */
    snowFlake.addColorStop(1, "rgba(255, 255, 255, 0)");    /* 找16进制的RGB 颜色代码。 */
    ctx.save();
    ctx.fillStyle = snowFlake;
    ctx.beginPath();
    ctx.arc(this.x, this.y, this.size, 0, Math.PI * 2);
    ctx.fill();
    ctx.restore();
};
/* 创建雪花-定义形状 */
function createFlakes() {
    var maxFlake = this.maxFlake,
        flakes = this.flakes = [],
        canvas = this.canvas;
    for (var i = 0; i < maxFlake; i++) {
        flakes.push(new flakeMove(canvas.width, canvas.height, this.flakeSize, this.fallSpeed))
    }
}
/* 画雪 */
function drawSnow() {
    var maxFlake = this.maxFlake,
        flakes = this.flakes;
    ctx = this.ctx, canvas = this.canvas, that = this;
    /* 清空雪花 */
    ctx.clearRect(0, 0, canvas.width, canvas.height);
    for (var e = 0; e < maxFlake; e++) {
        flakes[e].update();
        flakes[e].render(ctx);
    }
    /*  一帧一帧的画 */
    this.loop = requestAnimationFrame(function() {
        drawSnow.apply(that);
    });
}
/* 调用及控制方法 */
var snow = new snowFall({maxFlake:60});
snow.start();

js文件写完之后，最后只需要在/themes/icarus/layout/layout.ejs的body标签中添加如下代码：


    <script type="text/javascript">
      var windowWidth = $(window).width();
      if (windowWidth > 480) {
        document.write('<script type="text/javascript" src="/js/src/snow.js"><\/script>');
      }
    script>

鼠标点击特效

在/themes/icarus/source/js/src中新建click.js文件，复制下面的代码进去：

!function(e,t,a){
    function n(){
        c(".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;}"),
        o(),
        r()
    }
    function r(){
        for(var e=0;e<d.length;e++)
            d[e].alpha<=0?(t.body.removechild(d[e].el),d.splice(e,1)):(d[e].y--,d[e].scale+=.004,d[e].alpha-=.013,d[e].el.style.csstext="left:"+d[e].x+"px;top:"+d[e].y+"px;opacity:"+d[e].alpha+";transform:scale("+d[e].scale+","+d[e].scale+") rotate(45deg);background:"+d[e].color+";z-index:99999");< span>
        requestAnimationFrame(r)
    }
    function o(){
        var t="function"==typeof e.onclick&&e.onclick;
        e.onclick=function(e){
            t&&t(),i(e)
        }
    }function i(e){
            var a=t.createElement("div");
            a.className="heart",d.push({el:a,x:e.clientX-5,y:e.clientY-5,scale:1,alpha:1,color:s()}),t.body.appendChild(a)
    }
    function c(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 s(){
        return"rgb("+~~(255*Math.random())+","+~~(255*Math.random())+","+~~(255*Math.random())+")"
    }
    var d=[];
    e.requestAnimationFrame=function(){
        return e.requestAnimationFrame||e.webkitRequestAnimationFrame||e.mozRequestAnimationFrame||e.oRequestAnimationFrame||e.msRequestAnimationFrame||function(e){
            setTimeout(e,1e3/60)
        }
    }(),
    n()
}
(window,document);

最后在/themes/icarus/layout/layout.ejs文件中的
1

下一行添加如下代码：

1	<script src="/js/src/click.js">script>

版权信息

在/themes/icarus/layout/common/article.ejs中相应的位置做如下修改：

     
         <%- index && post.excerpt ? : post.content %>
     
+    <% if (!index && post.layout="==" 'post' post.copyright !="=" false) { %>
+        
+        本文标题：<%= page.title %>
+        本文作者：<%= theme.author %>
+        本文链接：<%= post.permalink %>
+        发布时间：<%= post.date.format("yyyy-mm-dd") %>
+        版权声明：本博客所有文章除特别声明外，均采用 CC BY-NC-SA 4.0 许可协议。转载请注明出处！
+        
+        
+    <% } %>
     <% if (!index && post.tags post.tags.length) { %>

给版权信息增加样式，在themes/icarus/source/css/style.styl中作如下修改：

+.post-copyright
+    font-size: 1rem
+    letter-spacing: 0.02rem
+    word-break: break-all
+    margin: 2.5rem 0 0
+    padding: 1rem 1rem
+    border-left: 3px solid #FF1700
+    background-color: #F9F9F9

网站运行时间

在/themes/icarus/layout/common/footer.ejs

<span id="timeDate">载入天数...span><span id="times">载入时分秒...span>
            <script>
                var now = new Date(); 
                function createtime() { 
                    var grt= new Date("12/28/2018 12:49:00");//此处修改你的建站时间或者网站上线时间 
                    now.setTime(now.getTime()+250); 
                    days = (now - grt ) / 1000 / 60 / 60 / 24; dnum = Math.floor(days); 
                    hours = (now - grt ) / 1000 / 60 / 60 - (24 * dnum); hnum = Math.floor(hours); 
                    if(String(hnum).length ==1 ){hnum = "0" + hnum;} minutes = (now - grt ) / 1000 /60 - (24 * 60 * dnum) - (60 * hnum); 
                    mnum = Math.floor(minutes); if(String(mnum).length ==1 ){mnum = "0" + mnum;} 
                    seconds = (now - grt ) / 1000 - (24 * 60 * 60 * dnum) - (60 * 60 * hnum) - (60 * mnum); 
                    snum = Math.round(seconds); if(String(snum).length ==1 ){snum = "0" + snum;} 
                    document.getElementById("timeDate").innerHTML = "本站已安全运行 "+dnum+" 天 "; 
                    document.getElementById("times").innerHTML = hnum + " 小时 " + mnum + " 分 " + snum + " 秒"; 
                } 
            setInterval("createtime()",250);
            script>

改变自己的建站时间，然后就可以了。

目录粘性

在themes/icarus/layout/widget/toc.ejs中做如下修改

1 2	-<div class="card widget" id="toc"> +<div class="card widget column-left is-sticky" id="toc">

主题默认是三栏布局，并且显示了很多的 widget ，但在阅读文章时显得有些拥挤。而且粘性目录会有干扰，因此在文章页面，修改为两栏布局，并显示特定的目录 widget。
在/themes/icarus/includes/helper/layout.js中作如下修改：

     const widgets = hexo.extend.helper.get('get_config').bind(this)('widgets');
-    return widgets.filter(widget => widget.hasOwnProperty('position') && widget.position === position);
+    if (this.page.layout !== 'post') {
+        return widgets.filter(widget => widget.hasOwnProperty('position') && widget.position === position);
+    }
+    if (position === 'left') {
+        return widgets.filter(widget => widget.hasOwnProperty('position') && (widget.type === 'toc' || widget.type === 'profile'));
+    } else {
+        return []
+    }
