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:

\themes\next\layout\_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>

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

博客目录\themes\next\layout\_macro\sidebar.swig尾部中引入:

{% include '../_custom/clock.swig' %}

示意图如下:

注:代码块要放置在sider-innerdiv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\themes\next\layout\_macro\sidebar.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-innerdiv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\themes\next\_config.yml

# 侧栏粒子时钟
diy_time:
  runtime: true 
  clock: true # 粒子时钟
