paragraph with vertical line on its left
- by Flavius
Hi
What is the easiest way to have a paragraph with one or with two vertical black lines on its left?
I have something like this so far:
\newcommand{\attention}[1]{\begin{huge}!\end{huge} #1}
But instead of a huge exclamation mark, I want a vertical line, whether the paragraph is one- or multi-line.
