Hexo博客添加粒子时钟特效 博客应用canvas粒子时钟的操作步骤：
在themesnextlayout_custom目录下，新建clock.swig文件，内容如下：
<div style="">
<canvas id="canvas" style="width:60%;">当前浏览器不支持canvas，请更换浏览器后再试</canvas>
</div>
<script>

</script>引用代码
直接引用或者通过配置文件配置，二选一
直接引用
在博客目录themesnextlayout_macrosidebar.swig尾部中引入：
{% include '../_custom/clock.swig' %}示意图如下：
注：代码块要放置在
sider-inner的div块中，放在div块的位置决定时钟样式的展示位置。我选择放置在尾部，看着效果好点。
通过配置文件配置
1、在博客目录themesnextlayout_macrosidebar.swig尾部中引入：
{% if theme.diy_time.clock %}
<!-- canvas粒子时钟 -->
{% include '../_custom/clock.swig' %}
{% endif %}示意图如下：
注：代码块要放置在
sider-inner的div块中，放在div块的位置决定时钟样式的展示位置。
2、在主题的配置文件中加入应用代码，配置文件位置是博客目录themesnext_config.yml：
# 侧栏粒子时钟
diy_time:
runtime: true
clock: true # 粒子时钟
