Is it possible to set text size of sections to a particular value, say 11pt?
\documentclass{article}
\usepackage[utf8]{inputenc}
\begin{document}
\section{Introduction}
Bla Bla
\section{Thank}
Bla Bla
\end{document}
Here I want to set 'Introduction' & 'Thank' at 11 text-size.
You can use the
titlesec
package:
