Hello,
This is possible in Css but we have a better method to suggest, first have a look on
this documentation
.
This will allow you to create override view from default HikaShop view, here, the show_default (or show reverse).
Another tips, in Main HikaShop Configuration, and Advanced tab, go in Advanced settings part, look for the Display view files option.
This option will display on your frontend the view references
product/show_default by example.
Hope this will help you to achived what you ,need.
regards
