Customisation Questions

Hello, My site is under development at http://securesearch.co.in/demo/ I have 3 questions for you: 1) I am trying to customise the Main Menu such that the item on which hover also changes the background, so that the dropdown portion appears connected to it. An example of this behaviour is at http://envato.tabvn.com/demo.php?theme=coworker Can you please advise from where I can change the hover bgcolor for the menu? 2) I need to apply the image effect used for Highlight Rooms to the 3 images at the top. How do I use Lightbox or the appropriate effect to those images? 3) I have added a SecureSearch Advantage table in the right column. I need to custom format the table with rounded corners, background, etc. How can that be achieved? Thanks, Ninad
