Question

I hava an angular 4.4.4 application with material 2.0.0-beta.12 and I want to use the mat-expansion-panel from material design.

This is my code

Answer 1

Instead of /deep/ you should use ::ng-deep, which is an alias provided by angular. Support for /deep/ etc. is already removed from chrome browser. So in your example that would be:

::ng-deep .parametersPanel .mat-expansion-panel-body {
    padding: 0;
}
