CSS for panel

Hi,

 

I have my own css-file defined and want to apply it to a panel where the id has the value “header”, so that the background of this component is black. Here are the snippets:

 

css:

 

#header{

      background: black;

}

 

Jsp:

 

<tc:page applicationIcon="images/ico/favicon.ico&quot; label="$">

            <tc:style style="tobago-resource/html/standard/standard/style/style.css";/>

 

            <tc:panel id="header" width="1200px">

                  <tc:image value="images/jpg/borte_left.jpg&quot; height="62px"

                        width="1000px" />

            </tc:panel>

 

…

 

Unfortunetly that doesnt work. What am I doing wrong?

 

Regards, Mario
