It does not border the full argument only the first letter ...

Any advice?

Thanks a lot,

To me it's not really clear what you are aiming at. So I guess that the empheq package from the mh bundle could be helpful.

Hi domi505,

\boxed requires curly braces to enclose its argument; otherwise, it will only affect the first character after the command. However, if you try to do something like

Code: Select all

Code, edit and compile here:

1

3
4
5
6

\documentclass[a4paper]{article}
\usepackage{amsmath}
\newenvironment{test}
  {\gather\boxed{}
  {}\endgather}
\begin{document}
\begin{test}
    123
\end{test}
\end{document}

Run LaTeX here

then you will obviously get errors during compilation (due to the unbalanced braces in the arguments of \newenvironment). Some days ago, a similar problem was posed in this thread:

Use unbalanced brackets in /newenvironment (sic).

Take a look at phi's response.
