donation page with custom CSS

[zalel]

I am adding a Donation button to a website I designed.

When a user clicks the donation button, it goes to a generic PayPal page that's very unappealing. My goal is to match the exisiting pages, and then return yo my client's site after the visitor clicks Submit. Is there a straightforward way to accomplish this? 

Here is are links to the Donate page I'm working on: http://roxburyyouthworks.org/pages/donate_button-text.html.

Thanks, 

Nicky
