It might help not to use the visual editor. It's imprecise and can introduce mistakes that remain invisible. It's better to edit the source raw, and use preview as needed. But editing templates can be all the trickier because you're not just editing appearance&mdash;you're editing logic, not all of which will necessarily display itself on preview and will have to be tested. It may be a good idea to set up a sandbox page to temporarily test your templates with their different parameters.
