<md-radio-group name="more_options" [(ngModel)]="favoriteSeason">
<md-radio-button name="more_options" [value]="Summer" class="margin-r">Summer</md-radio-button>
<md-radio-button name="more_options" [value]="Autumn" class="margin-r">Autumn</md-radio-button>
</md-radio-group>
For material icons, there isn't any CSS attribute such as "content" which can be replaced with appropriate icon code to replace md-radio-button icon with some other material icon. Is there any way to replace default radio buttons with material icons through pure CSS?
