How to edit background for jquery corner atribute

[Robroy]

Hello, i've got some problem on my presta shop page. Due to fact that I used for the section div#page repeated vertically background image(1000px width, and 4px height to gain a gradient look), all the corners that are rounded by the jquery, got this awful looking white squares that fills space. I attached screens for better understanding of my description . In the meantime i found solution what atribute should be edited in jquery to mask that white spaces. $("myDiv").corner("cc:#fff round 20px"); where #fff is color that jquery fills rounded corners, but i can't find a place in prestashop files where i could edit that value. Anybody could help?

P.S Sorry for my english, but it's not my native language

Simple solution can be Photoshop. Make corner color same as your background color. There is not any #fff code, these header are in gif format and they are automatically filled with white color. Therefore I advice you to edit image in Photoshop.
