CSS button not working

[Steve-Mcl]

There you go...

Material design icon in `button` node

Believe me when I say I am not doing this to annoy anyone. I want to put this on a button as the "icon". <i class="material-icons"> repeat_one </i> Obviously I can't just put that in the icon field. My brain has failed me again in working out how to do it. Thanks.

Copy the code this ^ guy did here ^ into your button

Edit...
Forgot to say, it's probably not gonna work with extra stuff inside the <i>

Try this...

    <md-button class="md-button program-names darkred">
        <i class="material-icons">
            analytics
        </i>
        <md-tooltip>Device status</md-tooltip>
    </md-button>
