This online store, as well as climaterm.md was created by me on the OpenCart engine. I made similar modifications, because they were created for the same employer. I uploaded the module for uploading/downloading the goods through Excel files. The template I left the basic template, but I made changes to CSS styles and a little bit of code TWIG (HTML) template. I added clickable phone numbers in the header. Introduced OpenCraph meta tags (PHP) to display pictures correctly when posting links to Facebook, Viber, Messenger.
