All changes I’ve made to my website have been in the live version of Canvas without a child theme (until recently, I never knew there was such a thing). When installing a new child theme, is there a possibility of losing any changes that I’ve made in the parent theme (I don’t even remember what changes I’ve made)? Thanks!
Nope you won’t loose any of the changes you have made in Canvas by installing a Child theme. You only really need a child theme if you are making custom.css changes. I’m currently working on a tutorial that will go into much more detail on how to tweak themes with CSS – should you need to.
