CSS to render markdown's blockquote

[thibault-v]

We can use markdown in most/all text editor of the website. The following (valid) markdown :

> this is my quote

Will generate the following (valid) html :

<blockquote>
<p>this is my quote</p>
</blockquote>

But, the incubator's CSS is not providing anything to render the "blockquote" tag :-/

I suggest that we add something like this in the website's css:

blockquote {
  padding-left: 10px;
  margin-left: 20px;
  border-left: solid;
  border-width: 2px;
  border-color: lightgrey;
  color: grey;
}
