title: Changing default width of blocks in LaTeX Beamer
body: <p>I use a custom Beamer theme for my presentations. In my presentations I'd like to use blocks (<code>\begin{block}…\end{block}</code>). These blocks are rendered slightly too wide to fit into my theme. Is there a way how I can set the default width of blocks, e.g. to <code>.9\textwidth</code>?</p>
