It really depends what you mean. Like in photograpy there are a few rules to make a better pic.
Like making sure its focused. The only time that rule doesn't apply is if that was the intent.

There are def rules when choosing the content of art. People say that art is about self expression but if you think about it there are some subjects that are a naughty no no. Taking pictures of Naked children for example.

-------
~I am a nobody, and nobody is perfect; therefore, I am perfect~

Some art may be considered trash, but its that artist's vision. Even if somebody doesn't follow the "rules" of photography, they aren't any less of an artist.

This is why avant-garde exists, which generally I personally think is retarded.

Like Yoko Ono's little thing with filming people's asses and calling it interesting art.

I don't know why that is artistic, but whatever.

No, art is freedom.

it is.
there are loose rules,( i'd be more inclined to call them guidelines) it works just as well when you break them.

A photograph must be taken by a "camera"
A painting should involve "paint"

And so on and so forth.

Art can be anything, but there are "rules" about what is actually pleasing to the eye.  Ever hear of the rule of thirds?  the rule of thirds is a "rule" for a reason.  It helps produce a more pleasing composition.  That doesnt mean the if you divide your photo into thirds it's suddenly a great photo, or that a photo that inst in thirds cant be wonderful.  It is simply a guideline.

Pick up any art or design book and there will be rules and theories.
