公式显示
如果需要显示公式，需要在Front Matter中添加math: md，详见: front-matter
When $$a \ne 0$$, there are two solutions to $$ax^2 + bx + c = 0$$ and they are:
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$
$$ x \href{why-equal.html}{=} y^2 + 1 $$

不带图片说明的IMAGE
TOC 功能测试
如需要显示 TOC Widget，需要在 Front Matter 中添加toc: true，默认设置了以后就会展示.
如需要根据长度显示，需要在 config.toml 中的 params.toc_show_len 设置具体值，如300，这样以后只有开启了toc并且文章字数超过300才会显示TOC目录.
需要注意的是字数获取用的是WordCount这个属性，如果你的内容是中，日，韩等，需要在config.toml中配置hasCJKLanguage = true
默认只显示h2-h3的标签，如需要调整，详情查看：Hugo文档 ｜ Configure Markup

My Subheading
A collection of textile samples lay spread out on the table - Samsa was a travelling salesman - and above it there hung a picture that he had recently cut out of an illustrated magazine and housed in a nice, gilded frame. It showed a lady fitted out with a fur hat and fur boa who sat upright, raising a heavy fur muff that covered the whole of her lower arm towards the viewer.
