Hi i am new on this forum, I am from Belgrade

I am beginer in web design.I work in dreamweaver 8 and i want to ask you one(simple) question for start.

How i can put background music into my whole web site without possibility controling this music for users.

You can't. Not all browsers support background sound, and those that do support background sound also allow the user to disable it.

Thanks very much, can you tell me is there any way to put this music at least on index page

There are many ways to attempt it, none of which are universally going to play for visitors. bgsound, embed, object, flash, etc.,
You can have music play for most users, but for it to play throughout your site it must be in a window that stays open.

See embedding background sound for starters.

My little piece of advice is to have volume="50' or some such control so that you don't hurt anyone.

Please see the FAQ entry How do I get an audio file to play automatically when someone visits my site?

Thanks
