Recommendation and problem., by kjodle Have you developed a child theme and added css to style.css successfully? Yes. There are plugins that will create child themes for you. I created my own theme for my websites. You can see the original theme on Github: https://github.com/kjodle/Atticus-Finch and you can see the child theme I created for it as well: https://github.com/kjodle/atticus-finch-child That should serve as a model for your own child theme. If you get stuck, don’t hesitate to ask! Reply To: Child theme css. Recommendation and problem.
