Enumitem - How to get custom label in line with the margin

Question

I have the following very basic question concerning the behavior of enumitem:

How do we make a custom (potentially long) label be in line with the margin?

Take the following MWE.

\documentclass{article}

\usepackage{enumitem}
\usepackage{blindtext}

\begin{document}

\blindtext

\begin{enumerate}[label=Counter \arabic*]
\item \blindtext
\item \blindtext
\end{enumerate}

\end{document}

How do we make the label Counter \arabic* be in line with the margins provided by the file?
[Of course the answer should be robust to the usage of additional packages such as geometry and it should not consist of some trial-and-error with leftmarginin the options.]

Also, a counter that gets at most one digit (from 1 to 9) is fine, just to avoid aligning with potential multiple digits.

Thanks a lot for any feedback.

Answer 1

You can have one of these, for instance, depending on where you want to have the list left margin:

\documentclass{article}
\usepackage{geometry}
\usepackage{enumitem}
\usepackage{blindtext}

\begin{document}

\blindtext

\begin{enumerate}[label=Counter \arabic*. , wide=0pt, font=\itshape]
\item \blindtext
\item \blindtext
\end{enumerate}

\begin{enumerate}[label=Counter \arabic*., wide=0pt, leftmargin=*]
\item \blindtext
\item \blindtext
\end{enumerate}

\end{document}
