Dreamweaver text boxes are ugly

I’m making a form using PHP coding. I’ve created a text box with photoshop and would like to know if it’s possible to create an “invisible” text box within the dreamweaver form so that I can take advantage of my design. Or do I have to use the ugly cheesy text box that Dreamweaver provides. Can I customize my own text box and still allow the form to function properly? Any tricks?

Thanks in advance.
