Updating website and website layout
Hey Dundee,
1. I’m not sure I understand what you mean by that, are you referring to other themes installed in your WordPress installation? If so then you can delete those if you don’t need them.
2. A Color Section element should work for that type of layout yes. Make sure the image is big enough to cover the element in question so that it looks good on all screen sizes.
Best regards,
Rikard
