I am sorry, but your post lacks contents to understand what you are asking.
Could you properly describe your question/issue, preferably with a minimal and working example?

sorry,I have solved my problems in my last reply.
I want to highlight code block by listings and set styles to make sure that code blocks breakline automatically
It can be achieved by

listings: true
include-in-header:
  text: |
    \lstset{basicstyle=\ttfamily,breaklines=true,keywordstyle=\bfseries\color{NavyBlue},morekeywords={}, commentstyle=\itshape\color{black!50!white}, stringstyle=\bfseries\color{PineGreen!90!black},columns=flexible,frame=single,framesep=1em
     }
