I am migrating an Ionic3 app to Ionic4 and I am having a hard time translating some of the CSS rules there.
For example, in Ionic3 I could style the
:after or an
<button ion-button> element with
<button> element is inside the
Shadow DOM of
<ion-button> and I am not able to put an
:before inside the
<button>. Is this possible with Ionic4 ?
