Html code in normal posts

Hey! How do I get this html code, to work in normal posts?

Code:

<div style="background-image:url(http://images7.alphacoders.com/348/348881.jpg);padding:5px;width:100%;height:500px;border:1px solid black;background-repeat:no-repeat;">
<style type="text/css">
div.background
  {
  width:100%;
  height:100%;
  background:url(klematis.jpg) repeat;
  }
div.transbox
  {
  width:88,5%;
  height:100%;
  margin:50px 35px 50px;
  background-color:#000000;
  border:1px solid black;
  /* for IE */
  filter:alpha(opacity=60);
  /* CSS3 standard */
  opacity:0.6;
  }
div.transbox p
  {
  margin:30px 40px;
  font-weight:bold;
  color:#FFFFFFF;
  }
</style><div class="background"><div class="transbox">
<p>
TEXT TEXT TEXT TEXT</p>
</div>
</div>
<br>
<br></div>

It works perfectly fine in the portal, where it should look like this:

It does work in a normal post I just tried it on my forum. You have to enable html on your forum for it to work.

Did you do this?

Yup but its not like its showing the text. Its going to look like this:
Where there aren't any kind of transparent box to write in, in the middle of the post.

Is this okay?

This should go into the css.

Code:

div.background
  {
  width:100%;
  height:100%;
  background:url(klematis.jpg) repeat;
  }
div.transbox
  {
  width:88,5%;
  height:100%;
  margin:50px 35px 50px;
  background-color:#000000;
  border:1px solid black;
  /* for IE */
  filter:alpha(opacity=60);
  /* CSS3 standard */
  opacity:0.6;
  }
div.transbox p
  {
  margin:30px 40px;
  font-weight:bold;
  color:#FFFFFFF;
  }

This code can go into the post.

Code:

    <div style="background-image:url(http://images7.alphacoders.com/348/348881.jpg);padding:5px;width:100%;height:500px;border:1px solid black;background-repeat:no-repeat;">
 <div class="background"><div class="transbox">
    <p>
    TEXT TEXT TEXT TEXT</p>
    </div>
    </div>
    <br>
    <br></div>

It works (:! thx!
