[xwiki-users] panel background

Hi all, I would like to set a given panel with a different background. Let's say, white, instead of the default #384554 in Albatross skin. I read in macros.vm panels' entries... ## Note: We pass the Panel name as an HTML class attribute so that it's possible to style ## the Panels selectively using CSS. Does this means that it is possible to change the background on a per panel basis by using CSS? In any case, I've tried to create a new macro assigning a different background color. This way... #macro(panelhiddenheaderwhitebackg $title) #set ($specialClassAttribute = "") #if ($paneldoc && $paneldoc != "") #set ($specialClassAttribute = $util.convertToAlphaNumeric($paneldoc.name)) #end <div class="panel expanded $specialClassAttribute"> <h5 class="xwikipaneltitle hidden" onclick="togglePanelVisibility(this.parentNode);">$title</h5> <div class="xwikipanelcontentswhitebackg"> #end Class for the div holding the content is set to xwikipanelcontentswhitebackg. I've created this class in colorsblack.css, imported by style.css, but there is no background shown for this panel. Using Firefox/Inspector, I can not see colorsblack.css referenced when inspecting this element. Please, is it possible to do this? Where am I wrong?
