TinyMCE and id css ignored

Question

some code is better than a thousand words:

script:

tinyMCE.init({
  mode : "textareas",
  content_css : "moncss.css",

            [...]       });

Html:

<div id="header">
     <div class="text1" style="display:none;">
        <textarea name="text" rows="4">Titre</textarea>    
     </div> 
</div>

CSS

 h1
 {  
   color:green;
 }
 #header h1
 {
   color:red;
 }

In my tinymce textarea, h1 is green and not red. Why ? How to solve this problem ?

Answer 1

I find the solution:

Use the inline editing :

script:

tinyMCE.init({

 selector: "div.header",
 inline: true,
 content_css : "moncss.css",
 [...]       });
