I'm new to titlesec
and LaTeX in general, trying to use it to achieve chapters in a {book}
class that are medium-sized and on the same line, viz:
Chapter 1: An Unlikely Event
Here's a minimized example:
\documentclass[english,12pt,oneside]{book}
\usepackage{titlesec}
\titleformat{\chapter}[hang]{\normalfont\medium\bfseries}{\chaptertitlename\ \thechapter:}{1em}{}
\begin{document}
\chapter{An Unlikely Event}
\end{document}
The error that returns is:
ERROR: Undefined control sequence.
--- TeX said ---
<argument> \normalfont \medium
\bfseries
l.77 \chapter{An Unlikely Event}
--- HELP ---
TeX encountered an unknown command name. You probably misspelled the
name ...
I think this is probably a simple error on my part, but I'm too young to know what it is.
Best Answer
you have used the command
\medium
, which doesn't exist. what you probably meant is\mdseries
, which is the default.since you responded in a comment that what you really want to do is change the size of the font, the command for that is
\normalsize
.
