[Solved] add to cart button

-- url of the page with the problem -- : testsite98.com
-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.4.3
-- PHP version -- : 5.4.4

I can't figure out how to change the color of this button. i tried Custom CSS and edited everything. im pretty sure its background-image: linear-gradient(to bottom, #ffffff, #e6e6e6); i changed it, deleted it. changed other files in the custom CSS. I tried a template override with no success. im familier with editing CSS. I was able to get some outlines and effects to change using custom css file however i did not get the desired result. Any help would be best regarded. thx

i figured it out it was the general display options button style
