Hello Dear KillerCodeMonkey,
first of all thanks for your project and your example for make the App more beutiful with a Rich Text
but i have a problem i do exactly what you did on your example but didn't work!!!
i upddate core-js and reinstall ngx-quill but not working (device and browser);
thank you for your solution

i think you missed to load / include the quill.core.css or quill.snow.css, because your screenshot looks exactly like this.
checkout the angular.json:
https://github.com/KillerCodeMonkey/ngx-quill-example/blob/master/angular.json#L26
You have to include them in your global css or in angular.json, because in other cases the viewencapsulation leads to wrong css selectors :).
So if you want to use quill only in one component, you have to set the view encapsulation to none and import the quill css there.
