Hi I’am trying go get to grips with Onsen-ui but I am struggling how to solve the following problem.

I want to add a button to the toolbar. I want to increase the size of the icon but what I find is the text to go with the button does not centre itself vertically with the icon.

 <ons-toolbar-button>
      <ons-icon
    icon="md-chevron-right"
    size="80px, material:24px">
  </ons-icon>
      Button
      </ons-toolbar-button>

Can anyone show me how I can centre the text vertically.

Thanks in advance.
