After installing CMS Opencart, the default Default theme is available. I want to create my own theme, let it be called ThemeDark. What do I need to do for this? Opencart version 3.0
Copy the catalog/view/theme/default folder, name the copy of ThemeDark and place it next to the catalog/view/theme/default . Next, clear the store cache. Next, change the twig files in the ThemeDark folder according to your design.
