Change product info box width

I’m currently using electro and I want to change the width of the grey box to the right of the product image that contains the price, stock order button etc, to 100% as at the moment it moves all over the place depending on whats in there.

Any pointers?

open style.css, and look for PRODUCT DETAILS STYLE and add width:?? px or %


[COLOR=“GRAY”]/* product details styles /[/COLOR]

[COLOR=“Magenta”].product-details-options {

background-color: #EEEEEE;

width:300px; [/COLOR] [COLOR=“GRAY”]/
**** products grey box - add width here ******/[/COLOR]

hope that helps.
