Child Themes

Before – otherwise you will have to redo some of the work you have done – which can, in some cases, be time consuming and complicated.

Awesome, thanks for the swift response. Am i best downloading/uploading all the files or just the ones that I have edited?

Definitely only put the .php files you have changed in the child theme, but note that style.css and functions.php file do not get copied in their entirety to the child theme.

Right, perfect.

Thanks for your help!
