Writing posts in the forums: Help needed

I'm in the process of writing a long-form piece in the forums, you're not obligated to read it but I was wondering whether anyone knew how to get the large orange pop-out quotes that are often used to draw attention to a specific line or sentence.

It'd be massively helpful if such tips didn't require extensive knowledge of HTML or CSS as I have no knowledge of either >_<.

Thanks in advance guys
