Sorry for making duplicate Topic but it is very important to me because i don't understand this topic by looking other related topics. Actually i am in process to build a WordPress theme and i am working on it, when i look into other themes source codes usually i find this code.
and i understand its something related to do_action();
So my question is that why we use this function in wordpress? and what is the job of this function and can we have a benefit of using this code on every starting and ending html tags in theme?
Thanks in Advance, Regards aran
