How do I design a home page like InvisionPower.com? Is there a guide for this? I know just about anything is possible with pages but a lot of time is need to learn the CSS a basic template that I can put into a block will be very handy and much appreciated.

It depends on what you want from it. 

• Use the WYSIWYG editor with Pages. Just create a new page, drop one in and edit it as you will.
• The way you'd achieve a quality similar to IPS' home page is by doing a custom HTML home page. It's really not that hard to do it yourself. But if you can't, you could hire someone to or there might even be people willing to help you out for free.
