Add font style to Part of Product Name

Hi there,
Opencart version 1.5.2.1
Product Title on Product Page -
We would like to add font style/color to part of the Product Title on product pages.
Example: Title = <h1>Eclipse Curtains</h1> <font style italic> Buy as a Readymade or go custom</I>
(so technically 2 headings just on same line) or any suggestions would be great to easily implement this please
thanks for looking
