Depending on your theme, just creating an href link anchor to a product tab might or might not work i.e. it might not scroll to it as it’s currently closed.
Here comes a way to create href links that not only scroll to the tab, but also open it in case it’s closed (this will guarantee the anchor scroll to the tab). Also, a little jQuery “animate” will provide the smooth scroll and enhance UX. Hope you enjoy!
