Time for action – using an environment to adjust the font size

We will produce a title with a larger and bigger font:

1. Create another small document with this code:

   \documentclass{article}
   \begin{document}
   \begin{huge}
   \bfseries
   A small example
   
   \end{huge}
   \bigskip
   This is just another small illustrative example.
   \end{document}

2. Typeset to see the result:

   

What just happened?

By writing \begin{huge}, we told LaTeX to switch to a huge font size just like with the \huge command. \end{huge} informs LaTeX that this size change should end now. From this point onwards, the font size is the same as before \begin{huge}.

Inside this environment, we use the declaration \bfseries . Note that the effect of this declaration ended together with the end of the environment.

The empty line before \end{huge} denotes a paragraph break. Using the command \bigskip , we skipped some space vertically.

For every declaration there's a corresponding environment carrying the same name except the backslash. Using environments...
