# It is possible/make sense to add a mark to hide part of text?

In mathematics (and in other sciences), often there is no unique answer, the same problem can be resolved by different approaches, and often one can learn something from each one.

So in order to favour different approaches a nice way will be to add a spoiler like mark. Those that want the answer will just display it, but the ones that want to think they one approach will not.

You can now hide a portion of text with

>! Spoiler
>! text


It will be hidden until your mouse move on it, e.g.

Spoiler text

Nice! Does it work only for blockquotes? – Parth Kohli Dec 27 '12 at 13:44
@DumbCow: Yes . – kennytm Dec 27 '12 at 13:45
Can you do one for me in the comments? – Parth Kohli Dec 27 '12 at 13:46
@DumbCow: No. Well maybe you could abuse $\color{white}{\text{white text in }\LaTeX}$. – kennytm Dec 27 '12 at 13:48
