^ It still makes me wonder why, some doesn't understand it while this is the simplest way. What I did most is provided some codes & showed how to compile it...It's already there..(Spoonfeed) Now if they want to add some other js, all they do is to understand it....Study the scripts... I too started without any knowledge but I tried to study the codes. I started with css then to js. Helping is really nice but they should also try to help themselves not only depend on copy paste. I appreciate those I helped that they tried to study the scripts & are now helping others too. Although there are still others who don't try to help themselves& yet you get negative feedbacks Yes,trial & error is the best way for you to answer the question why...And it does really help. As of now...I'm enjoying my free time & trying to update my outdated layouts Anyways,happy tweaking to all
