# Extending fullwidth into one margin

I'm working on a résumé which places section headers in a widened left margin. I'd like to use a fullwidth environment for the heading at the top of the page. Formally speaking, this would extend into the left margin to line up with the section headers. However, I can only get the heading to extend about two-thirds of the way to the right margin:

I added a leftmargin=-1in to the fullwidth package declaration to get the proper left-alignment, but even without it, the heading doesn't stretch the whole way to the right margin, as defined. Why is this, and how can I correct it?

(I also get a warning on the \hline about a "misplaced \noalign", which may be related.)

\documentclass[10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[margin=0.75in, left=1.5in]{geometry}

% https://tex.stackexchange.com/a/1315/10906
\usepackage{titlesec}
\titleformat{\section}[leftmargin]
{\sffamily}
{}{0pt}{}
\titlespacing{\section}
{4pc}{1.5ex plus .1ex minus .2ex}{2pc}

\setlength\parindent{0pt}
\usepackage[leftmargin=-1in]{fullwidth}

\begin{document}

\begin{fullwidth}
\textsf{\Huge{John Q Doe}} \hfill johndoe@example.com
\hline
\end{fullwidth}

\section{Foo}
This is some brief free-form text about some stuff that I can do.  Did you know I do Thing~3 and Thing~4?  It's pretty cool; I know.

\section{Bar and Baz}
\ldots

\end{document}


Use adjustwidth from changepage instead. It allows you to adjust the margin widths for a specific piece of text (left and/or right; into/from the margins):

\documentclass{article}
\usepackage[margin=0.75in, left=1.5in]{geometry}

% http://tex.stackexchange.com/a/1315/5764
\usepackage{titlesec}
\titleformat{\section}[leftmargin]
{\sffamily}
{}{0pt}{}
\titlespacing{\section}
{4pc}{1.5ex plus .1ex minus .2ex}{2pc}

\setlength\parindent{0pt}
\usepackage{changepage}

\begin{document}

\textsf{\Huge John Q Doe} \hfill johndoe@example.com \par
\hrulefill

Also, \hline is limited to a tabular-like scope. Rather use something like \hrulefill.
• Thanks! I especially like how the use of \par and \hrulefill give a horizontal rule that better splits the vertical space between the heading and the first section. – Tim Parenti Aug 10 '15 at 20:54
