Angular Material 2 : How to style an md-grid-tile?

To avoid messing with your whole project, use in the component:

HTML:

<mat-grid-tile [colspan]="8" class="script-menu"> </mat-grid-tile>

CSS:

.script-menu >::ng-deep .mat-figure{
    justify-content: flex-start;
}

You can use ::ng-deep to override the default css of md-grid-tile.

css:

::ng-deep md-grid-tile.mat-grid-tile .mat-figure {
    align-items: initial;  /*vertical alignment*/
    justify-content: initial;  /*horizontal alignment*/
}
