I am trying to add a header to my pages and in doing so I ran into the problem of not being able to change the default markup of fancyhdr headers. More specifically, I want the header of every page to include the subsection and section without numberings and in regular text, so no italics or capitals.
The following MWE illustrates my problem.
\documentclass[10pt]{article}
\usepackage{fancyhdr}
\pagestyle{fancy}
\begin{document}
\section{Section}
0
\subsection{Subsection}
1
\newpage
2
\end{document}
The first page's header does not show the title of the subsection,
whereas the second page does.
Both however have (sub)section numberings and sport markup. I would like them to look like this:
I have tried renewing the appropriate commands which did not do me much good.
Any help is appreciated!
