I am trying to vertically align my icon in a button on IE / Edge. It works in Chrome, FF ...
I have tried everything, without success.
This is a HTML code:
<button>
<i class="material-icons valign add-property-button">
add
</i>
</button>
I have created a Plunker (JSFiddle not working on IE) which demonstrates the problem: https://plnkr.co/edit/awk2usjeNjhi83DxLOr5?p=preview
Thank you in advance
