Inner and boundary Hölder estimates for nonnegative weak solutions of quasilinear doubly degenerate parabolic equations are established. The proof of these results is based on studing some classes $\mathcal{B}_{m,l}$ which can be considered as an extensions of the classes $\mathcal{B}_2$ introduced by Ladyzhenskaya–Uraltseva and the classes $\mathcal{B}_m$ introduced by DiBenedetto. Imbedding of the classes $\mathcal{B}_{m,l}$ in appropriate Hölder spaces is proved.
