How to change the size of the modal window?

Hello,

We would like to know how to change the size of the modal window? Currently, the size is 600x450. We tried to change it in css custom tab editor, but this is not working (#sbox-window element).
This window is opened when user clicks on the "Term and Conditions" link.
Please advise us.

Thanks
Bertrand

Hi,
The width and height size of modal box are generated by Joomla core (Modal function), Joom Donation doesn't setup with and height size of modal box.
