I’ve never seen anyone have an issue with the code snippets, it’s much easier than you think. If you’re new to WordPress all you have to do is add those code snippets inside a “Text” widget (drag a text widget into one of the Widget areas first)…..then all you have to do is replace the text or image with your own text or images, and that’s it. It may look difficult at first if you’re not a coder, but it’s only basic HTML so you shouldn’t have a problem with it.
