Ok, so here for example let's say I want to embed a long gist such as doing:
<script src="https://gist.github.com/benanne/3274371.js"></script>
Link to gist: https://gist.github.com/benanne/3274371
However, the embedded Gist is too long in my webpage and I would like it to show as just a few lines that could be either scrolled or unwrapped by clicking, etc.
Is that possible? How?
