If you are using PHP for creating a website, it will turn into a mess if you don't use separate files for CSS & Javascript. It is not that much of a problem as external javascript functions are not that difficult to call from html or php files. The code looks neat and we can differentiate the problem areas more accurately. The problem obviously resides when you use ASP.NET & call external javascript files. ASP.NET assigns different client side and server side ids for controls. It maybe a good idea there to discard the external coding of javascript if javascript functions are not called
