I can't use HTML within posts?

Forum link: http://oprp.forumotion.com/

So even after I enabled the option to use HTML on the forum, when try to use code within my post it won't display.

Code:

<div style="width:400px;height:auto;background-color:#f7f7f7">
  <div style="width:400px;height:45px;background-color:#820000;"><span style="text-align:center;color:white;font-size:15px;"></span></div>
  ee
</div>

That's the code I tried putting in a post, and I know it works...

Did you set it in your profile?

What do you mean?

Profile (navbar/menu) > Preferences
Always allow HTML :

Ohhhhh, thank you.
