Custom CSS for WebUI

is it possible to customize any node in the WebUI of RTC with a Custom Theme including a CSS as it is descibed here -> Theming

I've already uploaded a zip containing a css that tries to modify the WebUI and activated it. But it seems that it is not included when i open the page i tried to modify.

here is the content of the css(should modify the wikimarkup tables, the first 2 rules were for testing only):

.detailsSplitTableWrapper {
    background-color: lightblue;

.default_WTH .odd td {
    background-color: lightgray;
.default_WTH th {
    background-color: lightblue;
    border: black solid 1px;
.default_WTH,.default_WTH td,.default_WTH th {  
    border: black solid 1px;
    border-collapse: collapse;
    padding: 5px;

Is it even possible to modify these elements? Or have i done something wrong?

Thanks for your Answers.

ps: The used Version is 3.0, but we get 4.0 in late October.

The 5 Themable Nodes are documented in the Theming Wiki page 

The content can be provided as JavaScript dijits or as html static content in the theme.  The JavaScript dijits can be in any JavaScript (.js) file in the theme.  The html content has to be in specifically named files.

See Custom HTML and Custom Javascript in the documentation to find the specific names.

The JavaScript dijits take precedence over the html content.

First of all we don't recommend playing with CSS outside of content you add to Themable nodes.  The CSS of the Web UI provided by RTC is not part of our APIs that we support across releases.  If you do make these changes they are not changes that we can guarantee will work in future releases, or that we will notify our customers about changes that may affect them. 

 Some things to try: 

1.  Clear your cache, we've experienced some issues with caching, but only in the session that sets the theme.  After it's been set, any other login should see the content.  This doesn't always happen, we're looking at fixing this in future releases.
2.  Use Firebug or Chrome/Safari's developer tools to verify that the css content is coming into the page.  Look for a call to /<root>/_theming/allThemeCSS
3.  Then I'd verify that the rules are applicable to the elements and not being overridden by more specific css rules.

Let me know if that helps.

Thanks for your help, i will try this. But I still have a question.

How can i find out which nodes are themable? Is there a document where i can find this information?
