css sheet not styling

Hi,

I have been adding CSS changes for the lightbox view of Nextgen Gallery on my website, but unfortunately no changes I make appear on the website. I’ve tried it direct on the custom stylesheet that comes on the plugin settings and also on my theme’s custom stylesheet.
The tags I am using from Google Chrome are:

#fancybox-content{
  border:none;
  width:auto;
}
#fancybox-title-inside{
margin:0px;
}

But nothing happens and the display is really ugly now.

Please have a look at how lightbox is being displayed and let me know in case you find out why ngg is not responding to my css codes.

Thank you.

Julia
