thank you John..

one more summarized question!!

Let`s say I am creating a web site (which is www.msn.com) and designing all pages with XWD. My index page is their main page. Please check the msn.com and you see search button on the top of the page. So, what I should do is to assign my php code to the search icon. Next is that I will just put blank page as the top page and link it to the second page which is index page. Also just change the page filename as index.php and when it is published, the result will be www.msn.com
Hopefully, it is right??

by the way, do you think we can totally create msn.com with XWD of course with additional html and php codes? What do you think? Also, do you think the index page of the msn is index.php or html?
thank you so much for help
