Site Style The second new feature that HCK 3 introduces is the ability to select from 3 different themes. Classic Theme The Classic Theme is what Home Page Construction Kit Version 2 was based on.  It uses a standard roll over feature to change colours on both the top navigation strip and on the side navigation panel. Tab Style The Tab Style uses the concept of Tabs across the top of the screen.  The background colour of the current page is used for the current tab to indicate what page the viewer is looking at. Along the side, a different style of roll over is used Roll Over Style The Roll Over Style is a variation on the Classic style with a different way to indicate links and the current page.
