How to create a button with the jquery colorbox class

Hi,

I’m making my e-commerce and I’m trying to make a “Size Chart” button with a 10px around the text, square button, color #800000 for the button and text #ffffff that points to the link of the size chart picture I uploaded to my wordpress.

So far, I did not been able to find out anything about that… I would like to write it as a text in my “product short description” so I can do it for every products that needs it without too much complication.

If you need more information, I will be more than happy to answer.

Thanks
