Markdown confict with katex

Two method for rendering katex

1. Render at server side
   • Jekyll 中使用 KaTeX SsKatex
   • Not sure it could works or not.
   • You need set config at _config.yml

        kramdown:
            math_engine: null
   

   • The math_engine be set mathjax as default
   • If you wanna use javascript for rendering, you’d better set it be null
   • For more selection for it, check here.

2. Render at client side -. Require you have katex.js and katex.css at head, katex will render when you brower open. -. So you need consider about the order of rendering markdown and katex -. For example, you have a md file like

    $ABC*$123$DE*F$
   

   -. It will convert $123$DE$ as Italic first -. And then the rendering for katex
