# How can I add thickness to a line?

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.

\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}

• Welcome to TeX SX! Could you please post a minimal; but complete code, illustrating your problem? – Bernard Jun 16 at 21:27
• Your answer is similar to this question: tex.stackexchange.com/questions/197278/…. Use titling package and put into the dots (for example 5pt) of the command \rule{3in}{....} to increase the thickness. – Sebastiano Jun 16 at 21:33
• @Bernard I've added a few lines of code. Hope it helps. – Sobhan Jun 17 at 12:05
