How to override styles of md-input-container in angular2?

I have the following piece of code for md-input-container using angular material design:

<md-input-container>
      <input mdInput [placeholder]="'common.password' | translate" type="password" formControlName="password" (change)="onPasswordChange($event.target.value)" required validate-onBlur/>
      <md-hint *ngIf="frmLoginInfo.controls.password.pristine" class="s-text-caption s-hint">{{ 'signup.pwdRule' | translate }}</md-hint>
</md-input-container>

This container has a div inside with class (mat-input-wrapper) which has a padding of padding-bottom: 1.296875em.

How do I override this padding style of the container?

PS : Adding class to the container and making the padding: 0px as important also doesnt work.
