[Tex/LaTex] How to reproduce this box in tcolorbox

Question

I'm working with tcolorbox, I saw the pdf here and I want to reproduce the little green box in this image:

Can anyone help me please?

Answer 1

This is a \newtcbox called mylib and defined in tcolorbox.tex:

\documentclass{article}
\usepackage[many]{tcolorbox}

\newtcbox{\mylib}{enhanced,nobeforeafter,tcbox raise base,boxrule=0.4pt,top=0mm,bottom=0mm,
  right=0mm,left=4mm,arc=1pt,boxsep=2pt,before upper={\vphantom{dlg}},
  colframe=green!50!black,coltext=green!25!black,colback=green!10!white,
  overlay={\begin{tcbclipinterior}\fill[green!75!blue!50!white] (frame.south west)
    rectangle node[text=white,font=\sffamily\bfseries\tiny,rotate=90] {LIB} ([xshift=4mm]frame.north west);\end{tcbclipinterior}}}

\mylib{test}

\end{document}
