Been writing code since 1977, but know nothing of javascript and NEED to create some clever intro "Splash Screen" client-side ... and don't want to do it with raw code. Was hoping there was a GUI that would make writing the code easier ... but cannot find it on this site. GreenSock looks like what we need, but is there a GUI ... or must all code be written the old-fashioned way: change and test, change and test, change and test? index.htm
