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:

1
{% 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:

1
2
3
4
{% 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
