I have seen many answers to this question, but all of them seem very complicated and I don't understand how they work at all (copy and pasting them into my code doesn't seem to work either).
I should also add that I'm completely new to this.
All I want is a simple code that takes the default section title in LaTeX
and fills it in to become something like
This is what I currently have:
\documentclass[11pt, oneside]{article} \usepackage{geometry} \geometry{a4paper} \usepackage{graphicx} \begin{document} \section{Introduction} \end{document}
Any help will be much appreciated!
