hide a div in master page from content page.

Hi,

I used the following link for doing the page preloader.

http://www.aspsnippets.com/Articles/Display-loading-progress-image-when-Page-Loads-or-does-PostBack-using-ASPNet.aspx

I used this code in the master page. So I need to hide the 'loading' and 'modal' in a particular content page. I am able to hide the loading div, but not getting idea for hiding 'modal'.

Please reply.

Thanks in advance
