I am trying to change the font size of a text in mat-toolbar, but nothing seems to work . In the plunker example i have 2 spans 'AAA product' and 'some long description' . how do i change the font size of these elements . applying style to the span doesnt seem to take effect. Any help is much appreciated.
<button mat-button (click)="sidenav.toggle()" >
<mat-icon>menu</mat-icon>
</button>
<span>AAA product </span>
<span class="test"></span>
<span style="font-height=10px">Some Longer description</span>
<span class="fill-remaining-space"></span>
