Angular material: no background color on mat-input on focus mode

Question

I have a mat-input field

  <mat-form-field>
    <input class='formulaInput' matInput [(ngModel)]='mathFormulaInput'>
  </mat-form-field>

and I am not happy with the blue background when it is focused on. Is there a simple CSS way of hiding this?

Answer 1

This has nothing to do with angular-material, but with your browser. Check the "user agent stylesheets". Most likely this comes from the browsers autofill ( input:-internal-autofill-selected) styles.
