How to change mat-icon size in Material

This question comes from the Material2 Github repo.

I still have problems to style a Material component that is wrapped in a custom component.

I have a <logo> component that contains <md-icon svgIcon="logo"></md-icon>

Adding:

:host { 
   .mat-icon {
    width: 100px;
    height: 100px;
    font-size: 56px;
  }
}

Will not apply to the Material component inside my custom component.

UPDATE: 2019-05-22

Newer versions of Material Design has the option to set [inline]="true" as a property on the HTML element.

I would recommend using that approach instead.

<mat-icon svgIcon="thumbs-up" inline="true"></mat-icon>

When using this, the icon will inherit from the parent container!

GLHF! :)

I have been getting some questions about this so I just wanted to make a clearer example of how to use it...

/* 1. Add this mixin to a "global" scss */

@mixin md-icon-size($size: 24px) {
  font-size: $size;
  height: $size;
  width: $size;
  line-height: $size;
}

/* 2. Then use it like this in you component scss */

mat-icon {
  @include md-icon-size(32px);
}

example usage

<mat-icon class="myIcon" svgIcon="search"></mat-icon>

:host {
  .myIcon {
    &mat-icon {
      @include md-icon-size(32px);
    }
  }
}
