hi, ty for the reply... unfortunately i decided to try another solution because of lack of time... and because of that link is not available...
but for future projects abantecart will be in my primary choices. I think admin is amazing well done and very user-friendly.
Still think, abantecart team may improve on give more accurate information on how to do the embed, more like telling if it is needed to embed also the shopping cart embed code (how to do it and where to put it in hltm5 for bootstrap websites) and also the manner how is explaining in the tutorial, the changing of links in the embed code, is a little bit confusing, perhaps just for me ( i don't know).
In my case i was trying to implement the embed code in the place of photos of a gallery, my plan was to put embed code of products created on abantecart admin, and replace the pre-existing photos in a gallery of the pre-existing bootstrap website, and then edit the css of the embed products for maintaining the same design I have before.
