Visually designing a PHP/Bootstrap site application in Dreamweaver CS5

[BlackReef]

Hello,

 

So I am working on a PHP website for a friend, and I have loaded the header.phtml and footer.phtml files in dreamweaver, but the files do not include .css calls or anything, so it basic code showing.

 

Could somebody please help explain how I can get the actuall website (offline version of it) to appear visually in DW?  I need to add a simple input form in the footer of the website, and I would like to handle it with CSS.

 

Thanks in advance,

-J
