  In this paper, we prove the existence of solutions to quasilinear elliptic
equations on a bounded domain of $\R^N$ under subcritical
Musielak-Orlicz-Sobolev growth. Our proofs rely essentially on Mountain Pass
Theorem with corresponding variational techniques. Furthermore, we establish
the sharpness of our central assumptions. As far as we know, our approach is
new, even for the Orlicz case.
