本文首发于Ray's Blog
近日在美化博客，给博客添加了一个Canvas时钟。

存在/themes/icarus/source/js下。
自己添加了一块菜单，存在/themes/icarus/layout/widget下，命名为clock.ejs。
如下。

<div class="card widget">
    <div class="card-content">
        <canvas id="canvas" style="width:100%;"></canvas>
        <script src="/js/clock.js"></script>    
    </div>
</div>

最后在主题配置文件中引入即可：

    -
        # Widget name
        type: clock
        # Where should the widget be placed, left or right
        position: left

效果见我的博客。
