Question: Is there a way to control font-size of headline?

[atifwaqar]

My code looks like :

<paper-card heading="0 Live Campaigns">
    <div class="card-actions">
        <div>
            ....
            {{model.CampaignsStats}}
            ....
        </div>                                    
    </div>
</paper-card>

but I want to increase/decrease the header font size depending on its content size, and also want to center allign the header. I tried to find some reference in your code examples, but couldn't find it. Any sort of help would be really appreciated. Thanks in advance :)

Yup, there's the --paper-card-header-text mixin:

paper-card.smaller-text {
      --paper-card-header-text: {
        font-size: 10px;
      };
}
