I have some widgets which create some nice effects for my html websites and I'd like to be able to use them in WordPress. I was told I just need to add the js and css links to the header.php file.
Initially, that sounded simple enough, but I've also been told that it's important to create child themes. And, I believe the header.php file resides in the main theme directory. Then, there is the issue of where the js and css files/directory need to reside. I believe they would reside in the child theme directory.
So, would I put the js and css links in the header.php file in the main theme directory? If my theme was in the "abc" directory and my child theme was in the "def" directory, how do I designate the links? Would it be ../def/... in the header.php file?
