Hi all. I am new in licensing. I read more then 20 article and i have still have question about GPL.
Q 1 - Can i use any theme in the wp.org as a starting theme? Off course i don’t use css and images. and link credit in the license text
Q 2 - Some themes on the themeforest have 100% GPL license. Can i integrate their header builder to my theme?
Q 3 - I know HTML and PHP are freely use but what about JS?
