  <mat-label>Favorite food</mat-label>
  <input matInput placeholder="Ex. Pizza" value="Sushi">
</mat-form-field>

Answer 1

tailwind is adding border-style: solid; which is causing the extra border to be rendered

quick solution would be to override the right border style

add this in the styles.css file

.mat-mdc-form-field.mat-mdc-form-field.mat-mdc-form-field.mat-mdc-form-field.mat-mdc-form-field .mdc-notched-outline__notch {
  border-right-style: hidden;
}
