Other template debugging techniques
Personally, I rarely use template hints. Perhaps this is due to the fact that I already have extensive experience with Magento frontend and more or less know where to look. Instead of template hints, I often just look for a characteristic place in the template. Usually it is a class name or ID and I search for it in the code. In any case, template hints can be useful especially if we have an extensive store, where templates can be overwritten by external modules.
In this short article, I showed you how to easily enable/disable template hints in Magento 2.3. You can find more about template debugging in the Magento documentation.
