What do you all think web development consists of? Is it just html/css? Does it include backend processes such as application servers that feed your front end web code? Databases too?

Since I do a little tinkering with code.....

I think web development is everything from the front end html/css/dhtml/etc, the middle layer (if you have one) of vb, c++, whatever code that talks to it and even the database code that may feed information to your whole site. If it has to do with the web site then it can be considered part of web development.
