Contact us CSS on variants

Hi,

You can do the same change in product / show.php where the HTML of the variants is generated.

However, I would still recommend to do this with CSS instead of view overrides.
If you do:
.hikabtn{ color: red; }
it will change the color of the elements with hikabtn everywhere, and you don't want that.
But what you can do instead is use the parent element class, like so:
.hikashop_product_contact_main .hikabtn{ color: red; }
That way, is will only change the color for the contact button and not the other buttons, even though they all use hikabtn.
