Text Formatting ⇒ begin{center} adds vertical space?

[tonyjnel]

Hi,

I am new to LaTeX and this community. This is my first post. I made a custom environment for Examples in my paper but when I center the example text it also adds vertical space between name of the example (Example 1) and the text below. I don't want it to do this and I am wondering if that is just a property of the command or if there is something weird going on caused by my environment or something.

Here is the code:

Code: Select all

\documentclass[12pt]{article}
\newcounter{example}\setcounter{example}{0}
\newenvironment{example}{\refstepcounter{example} \vspace{3mm} \noindent \textbf{Example \arabic{example}}\\ \indent}{\vspace{6mm}}
\begin{document}

\begin{example} \label{addexample}
\begin{center} Stuff \end{center}
\end{example}

\begin{example} \label{addexample}
Stuff 
\end{example}
\end{document}
\end{document}

I would expect the two examples to have the same vertical spacing but they don't. Do I have to manually subtract vertical space to make them look the same?

Thanks!

Hi Tony,

welcome to the board!

The center environment adds vertical space because it's implemented as a list environment. You can use \centering instead which doesn't add this space. See center vs. \centering for further information.

Thanks, Stefan, that did the trick

It also shifted the title of the example but I modified the environment by adding \flushleft before the title of the example to fix that.
