Creating a layout where theorems are in 'margins'

Question

I wish to design a document with the following mock-up layout, where theorems are separated from the main body of the text in a sort of margin:

\documentclass[11pt,a4paper]{article}
\usepackage{xcolor}
\usepackage[calcwidth]{titlesec}
\usepackage{tikz}
\usepackage{pgfplots} \pgfplotsset{compat=1.12}
%Underlining ruler for subsections
\titleformat{\section}%
  {\normalfont\Large\bfseries}% format
  {}% label
  {0mm}% sep
  {%
    \vadjust pre{%
      \color{gray}%
      \hrule width \linewidth height 0.5pt\relax
    }%
  }% before-code

\begin{document}

\section{Example Section}

\end{document}

How do I achieve this?

You can take a look at the documentation of ntheorem: a \theoremindent length is defined, which is 0 by default. Other suggestion: the same package defines a margin theorem style. — Bernard, Dec 02 '17 at 17:19
You may want to have a look at Theorem name, number and note in margin column with amsthm. — Matthias, Dec 02 '17 at 20:09
While there are similarities here, it is not identical to the question I asked. I would appreciate a new solution which puts the section title and horizontal rule in the margin as well as the theorems etc — wrb98, Dec 03 '17 at 00:16
Also, in case there is some confusion, I would like all the text in that section to be separated from the theorem titles and numbers, not just the text in the theorems — wrb98, Dec 03 '17 at 14:05

I think what you want is paracol package.

\documentclass[11pt]{article}
\usepackage[margin=1in]{geometry}
\usepackage{paracol}
\usepackage{amsthm}
\newtheorem{thm}{Theorem}
\newtheorem{mydef}{Definition}
\usepackage{xcolor}
\usepackage[calcwidth]{titlesec}
\usepackage{tikz}
\usepackage{pgfplots} 
\pgfplotsset{compat=1.12}
%Underlining ruler for subsections
\titleformat{\section}%
  {\normalfont\Large\bfseries}% format
  {}% label
  {0mm}% sep
  {%
    \vadjust pre{%
      \color{gray}%
      \hrule width \linewidth height 0.5pt\relax
    }%
  }% before-code



\begin{document}
\columnratio{0.3}
\begin{paracol}{2}[\section{Example Section}]

\begin{thm}
Blah blah blah blah blah blah blah blah blah
\end{thm}

\switchcolumn 
Some text blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah

\switchcolumn 
\begin{mydef}
Blah blah blah blah blah blah blah blah blah
\end{mydef}

\switchcolumn 
Some other text blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah

\end{paracol}
\end{document}
