I cannot seem to find an edit or delete option so I will just keep on updating and posting as I go… For now I opted to use the Code Snippets plugin since setting grandchild themes is a really bad practice according to most WordPress authorities, plus it rises more issues than it solves since I would have to reference both the child and parent theme codes and make sure to be using everything in the right order, etc.
An example of a customization I would like to do is:
Changing the “near” input field in the home page header to a dropdown select with pre-set state choices.
