I have this title with two lines surrounding it.
\title{\line(1,0){350}\\Whatever\\\line(1,0){350}}
I want to adjust thickness to these lines and I tried playing with numbers in the parentheses but that didn't change anything. Thanks for your support in advance.
Here is the complete code for this article
\documentclass[a4paper,12pt]{article}
\title{\line(1,0){350}\\Whatever\\\line(1,0){350}}
\author{Me}
\begin{document}
\begin{abstract}
Lorem Ipsum Dolor Sit Amet concecteture...
\end{abstract}
\end{document}
titlingpackage and put into the dots (for example 5pt) of the command\rule{3in}{....}to increase the thickness. – Sebastiano Jun 16 '19 at 21:33
