With lots of help from this forum I have done a bit of customisation on the Sydney theme and have just realised I should probably have been doing this in a child theme. So I installed the Sydney child theme and matched the customisation so the site looks the same as it did when the parent theme was active.
My question is: do I need to retain the parent theme on my site? If so, can it stay as it is (with all my previous customisations) or do I need to delete it and reinstall a clean copy of the parent theme?
Sorry if there is an obvious answer to this - as you may have guessed I haven’t used child themes before!
Thanks in advance for your help,
