Removing Background slider container

So I have been able to remove the black background that the slider images sit on in firefox, but I can not get it to go away in chrome or IE. Here is the site... http://center10.com/magnet
Please take a look in all browsers and let me know why the background is still showing and my rounded corners are not showing either. This is for the home page slider area. Thanks.

 

Ok, I have removed all #main css code that would be associated with the slider background and it still is there in IE, Chrome and Safari.
My rounded corners are there if I use Chrome's DevTools to take away the background. The DevTools Show the css code, so where is it coming from??? The background has a strikethrough so I could see my rounded corners.
#main {

1. ​

   background: none repeat scroll 0 0 #000000;​
2. ​

   border: 1px solid #000000;​
3. ​

   padding: 10px;​
4. ​

   position: relative;​

}
