Ajax & Html. HOW? Thanks ? Hello, I would like to redesign an existing website in Dreamweaver which contains PHP, SQL, Java, Ajax & Html. The new designs have already been made on paper and usability issues have been sorted out. I just need to make the old site look like the new designs while still insuring all of the existing code in the old site still works. Where should start? Do I first make a template and then just copy small pieces of code in at a time? Or alter the existing pages which contain the code?

Thank you
