Here's one possibility admitting page breaks using tcolorbox:

\documentclass{article}
\usepackage[skins,many]{tcolorbox}
\usepackage{lipsum}

\definecolor{myblue}{RGB}{32,92,195}

\newtcolorbox{mybox}[1]{
   freelance,
   breakable,
   title=#1,
   left=0pt,
   right=0pt,
   width=.9\textwidth,
   enlarge left by=.1\textwidth,
   coltitle=black,
   frame code={},
   interior titled code={
     \draw[myblue,ultra thick] 
       ([yshift=5pt]frame.south west) |- ([xshift=60pt,yshift=-4pt]title.south west);
   }
}

\begin{document}

\lipsum[4]
\begin{mybox}{The title}
\lipsum[4]
\end{mybox}
\lipsum[4]

\end{document}

enter image description here

And with mdframed:
