Markdown模式的一些额外用法

本应用使用的Markdown编辑器是Vditor，它支持一些特殊用法，数学公式、脑图、流程图、时序图、甘特图、图表、五线谱、Graphviz、Flowchart

下面的例子节选自Vditor的教程

数学公式

多行公式块：

\[\frac{1}{ \Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{ \frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} { 1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}}{1+\cdots}} } }\]

行内公式：

公式 $a^2 + b^2 = \color{red}c^2$ 是行内。
