Source code - What is it?

Hi, sorry for my lack of knowledge in this matter.

I would like to know what for is that "source code" thing I see up there at the post options.

I mean, what kind of codes, what would they do in a forum post, etc.

Can someone give me an example?

Thanks

Not sure what you mean.  Are you asking about the icons?

Thanks.

I kinda knew.

What I mean is, are there any applicable examples around chess.com's topics?

I always take a ride at the forums but never saw something made up by changing the source code.

Whenever you hit "Quote" to quote a post and reply to it, you will see the HTML-5 source code appear briefly in the New Post window.

It will look a bit like this:

<p>Whenever you hit "Quote" to... </p>

If you know HTML, you can write some code to display things and customize it the way you want which is not possible by the options provided to you by the site. 

 Though I mean a hole at the player's profile.

I don't know if that's possible, though.

But it would be so damn awesome!

 <retracted, seeing things incorrectly>. I rarely post new topics so haven't noticed that was available. Kind of surprised it's even an option since it isn't in replies.

But that would be HTML markup and should only impact your initial post. 

It's on V3 dude.

 Its also a movie from 2011 starring Jake Gyllenhaal. 

 Having a Monday moment on Thursday, I guess.

Was mentioning that movie to some people earlier this week.

His latest one is "Noctunal Animals".  Doesn't look that hot to me, just your basic good over evil.

Thanks.

Ya' welcome's my gud buddie!
