Convert jQuery to javascript (hide block after click on blank space)
<p>Hello dear programmers Stack Overflow. I started to learn javascript and for a while (until you learn to write complex programs) would do without frameworks to understand the principles of the "native" code. I ran into the problem and found its realization ... but jQuery that difficult to understand deeper processes.</p>

<p>Can someone help analyze this example into its component? I would be extremely grateful for such a kind person help! :)
Sorry for the broken English.</p>
