问题
using the jquery ui modal dialog, the background shades grey (i assuming this is being driven by my theme roller). For one specific modal dialog i want the background to be darker than what i am getting by default with the default options.
More importantly, how can i change the shading on the background screen when i load one specific dialog. In this case, I DON'T want to change the css of my theme roller css as i only want this to apply to one specific page.

Could you place the following in your special page : thus overriding the the background
<style>
.ui-widget-overlay {
background: url("images/ui-bg_flat_0_aaaaaa_40x100.png") repeat-x scroll 50% 50% #AAAAAA;
opacity: 0.3;
}
</style>
Just adjust the opacity to the level you want and for IE you might need modify the image as well..
Hope i understand you...
