When resizing screen or when viewing with smaller screens, the links on the nav bar drop below the text often so far as to think there is no link there. This also applies to the top logo. When viewing from a full screen size on a wide monitor everything is fine. I had thought the href was on div or the class and when it was resizing it moved it away. But I have been unable to find it.
Pls remove the above custom CSS which you have added.
And can you make use of dropdown menus like in our demo site menu item “Features”.
The white space you are getting is due to revolution slider and rightnow the background is set to white. Pls remove it and add a slide which having same aspect ratio as that of our demo slide or adjust the slide setting in revolution slider.
