how about actionscript? but since you posted in this forum
you might already know about that.
So to give you a complete list of needed skills to create a
proper website you will need at least knowledge in:
- Flash/Actionscript (for your animation part)
- some serverside Technology if you want to persist data to a
database or file system, for beginners this would be PHP (the
easiest language for such purpose)
so if you are planning to build a website on you own wihtout
any basic knowledge: forget it!
You should probably stick to some WYSIWYG-Editor like
Dreamweaver or similar to get startet...but if you want to build a
"real" website, WYSIWYG Editors won't take you very far without
reaching their limits (as long as you don't know the basics of the
above mentioned technologies)
