Since you want it just on the home page:
1) Set home page as “1 column” in CMS
2) Create table in your design software (dreamweaver, frontpage..)
3) Add all the stuff you want (2 columns)
4) Copy the code to the cms home page…
Another option is to create a the design you want on a html document, upload to you server, create an iFrame, paste the code into your CMS home page
You don’t have to mess with the core code now… You can also create a flash presentation and embed it (dont forget to add wmode="transparentâ and ‘wmode’,’transparent’ to html embed code)
Hope this helps.
