Please don't make me say everything twice...
I had given you the link to the documentation already:
www.hikashop.com/support/support/documen...the-display.html#css
So, first read that. Pick i.e. the "default" frontend CSS. Again and again:
It will change numerous other display details in your shop, all of which you'll want to modify back to how you prefer things to appear. You will probably also try out turning HikaShop' "Use bootstrap design" display feature on or off.
There'll be immediate effect on your product page, but it'll cost you quite some work to have colours, fonts and other things set to the overall template style.
