Reduce space between columns in res.cls latex resume-CodePudding

How do I reduce the space between two columns in the res.cls?

I have the following code in my latex document right now

This is the main Latex file.

  %---
%   PACKAGES AND OTHER DOCUMENT CONFIGURATIONS
%---

\documentclass[margin, 10pt]{res} % Use the res.cls style, the font size can be changed to 11pt or 12pt here
\usepackage{hyperref}

\usepackage{helvet} % Default font is the helvetica postscript font

\usepackage{enumitem}

\setlength{\sectionwidth}{1.8in}
\setlength{\textwidth}{5.2in} % Text width of the document

\newcommand{\ts}{\textsuperscript}

\begin{document}

%----
%   NAME AND ADDRESS SECTION
%-----

\moveleft.5\hoffset\centerline{{\LARGE {{Google}}}} % Name at the top
 \moveleft.5\hoffset\centerline{\href{https://google.com}{https://google.com}}

%------

\begin{resume}

%----
%   EDUCATION SECTION
%----
\section{{\sc{Education}}}

{\textbf{Institute Name} }  \hfill Jul. 2018 - Jul. 2018 \\
Undergraduate \hfill USA

\begin{itemize} [leftmargin=0.5cm]
    \item GPA of 4.0 / 4.0
\end{itemize}

I am using the res.cls file for styling, in the same directory as the above file. Find the res.cls I am using here

CodePudding user response：

You have

\setlength{\sectionwidth}{1.8in}

Add the following combination of length changes after that:

\addtolength{\sectionwidth}{-0.5in}
\addtolength{\oddsidemargin}{-0.5in}

Any adjustment in \oddsidemargin will push the section title further into the left margin, hence the dual adjustment so it remains in the current position. Change the lengths to suit your needs.
