it looks exactly like what I have done in the past…..
“This directory can contain as little as a style.css file, and as much as any full-fledged WordPress theme contains:
1. style.css (required)
2. functions.php (optional)
3. Template files (optional)
4. Other files (optional)”
I think I tried with the functions as well, because I might need to change them in the near future. I am new to Worpress but not new to PHP at all.
I try again!
