How to style timepicker

Styles from the material/timepicker package can be customized using the timepicker-overrides mixin. This mixin accepts a set of tokens that control how the components will look, either for the entire app or under a specific selector. For example:
@use '@angular/material' as mat;

// Customize the entire app. Change :root to your selector if you want to scope the styles.
:root {
  @include mat.timepicker-overrides((
    container-background-color: orange,
  ));
}
You can find the full list of supported mixins and tokens below.
