一、前言
本篇博客内容为介绍当前博客主题以及所使用的目录组件，涉及详细代码及配置步骤
- 本主题特点在于简洁 —— 为阅读而生，没人任何多余的美化。自带护眼背景色(#DFEEDF)
- 本主题推荐使用 MarkDown 编辑器，适用于官方主题：SimpleMemory
- 新增：+展开/收起目录功能、+目录跟随标题滚动定位功能
- 新增：+移动端适配(单击目录跳转目标并收起)
- 新增：+图片默认大小 min--webkit-fill-available;height:122px、点击预览 0.9 倍原图，点击非图片区域退出预览
配置代码以实用为主，请不要过于在意格式细节，若有更好的实现，欢迎交流提供，感谢指正错漏
二、前期准备工作
2.1、申请开通 JS 权限
由于主题需要用到 JS 代码，因此需要您的博客申请并已开通 JS 权限
详见 设置 - 博客设置 -> 博客侧边栏公告（支持HTML代码） （支持 JS 代码）
三、具体配置步骤
3.1、基本控件设置
详见 常用选项 -> 控件显式设置
3.2、页面定制 CSS 代码
