Markdown 语法测试

参考自 PaperMod 的 Markdown 语法示例页面

This article offers a sample of basic Markdown syntax that can be used in Hugo content files, also it shows whether basic HTML elements are decorated with CSS in a Hugo theme.

Headings

The following HTML <h1>—<h6> elements represent six levels of section headings. <h1> is the highest section level while <h6> is the lowest.

H1

H2

H3

H4

H5

H6

如果要加粗的内容最末带标点符号，Markdown渲染会出现问题。例如在Obsidian中的这个bug。建议在加粗时，不要包括进最后一个标点符号。

Blockquotes

The blockquote element represents content that is quoted from another source, optionally with a citation which must be within a footer or cite element, and optionally with in-line changes such as annotations and abbreviations.

Blockquote without attribution

Tiam, ad mint andaepu dandae nostion secatur sequo quae. Note that you can use Markdown syntax within a blockquote.

Blockquote with attribution

Don’t communicate by sharing memory, share memory by communicating.

Most salamanders are nocturnal, and hunt for insects, worms, and other small creatures.

KaTeX

需要在文章头部加入：

katex: true

$$ \begin{aligned} KL(\hat{y} || y) &= \sum_{c=1}^{M}\hat{y}_c \log{\frac{\hat{y}_c}{y_c}} \ JS(\hat{y} || y) &= \frac{1}{2}(KL(y||\frac{y+\hat{y}}{2}) + KL(\hat{y}||\frac{y+\hat{y}}{2})) \end{aligned} $$

对于包括\的情况，需要再加一条斜杠来转义，如下：

\begin{pmatrix}
  a & b \\\ 
  % 需要多一条斜杠
      c & d
      \end{pmatrix}

$$ \begin{pmatrix} a & b \\ c & d \end{pmatrix} $$

对于包括_的情况，同样需要添加斜杠来转义，如下：

\underbrace{a}\_{b} - \underbrace{c}\_{d}

$$ \underbrace{a}_{b} - \underbrace{c}_{d} $$

也可以在公式外用{{< rawhtml >}}²包裹，则不需要添加斜杠：

{{< rawhtml >}}
$$
Y = 
\begin{bmatrix}
    \alpha_{1,1}\mathbf{x}_1 +...+ \alpha_{1,M}\mathbf{x}_M \\
    \vdots  \\
    \alpha_{N,1}\mathbf{x}_1 +...+ \alpha_{N,M}\mathbf{x}_M 
\end{bmatrix}
$$
{{< /rawhtml >}}
