I want to highlight some text in a block just as we are able to do so in latex beamer template or as we can see notes section in many books which has a box highlighted and perhaps have different background and fonts just like notes section in books.
I have already followed the answer for How to highlight an entire paragraph? but those are to just change background color which is not sufficient to me.
the text I want to make highlight may or may not contain math block / equation or inline equation but will definitely contain \begin{itemize}...\end{itemize} block

tcolorboxpackage can provide what you looking for. – Zarko Jan 05 '19 at 20:06tcolorboxis perfect and what I wanted. As I was ready to adapt any basic box I didn't added any sketch because I don't need to design any specific style. – Gahan Jan 06 '19 at 13:56
