Html 如何更改计时器S输入的Angular 字体大小

我想要更改此输入的大小

此处为.html组件

    <div class="time-picker" dir="ltr">
                                                    <ngx-timepicker-field [defaultTime]="'00:00'" [format]="24" [clockTheme]="theme"></ngx-timepicker-field>
                                                </div>

此处为.ts组件

import { NgxMaterialTimepickerTheme } from 'ngx-material-timepicker';

theme: NgxMaterialTimepickerTheme = {
        container: {
          bodyBackgroundColor: '#25bcbd',
          buttonColor: '#fff',
        },
        dial: {
            dialBackgroundColor: '#4fcbcc',
        },
        clockFace: {
          clockFaceBackgroundColor: '#e6e7e8',
          clockHandColor: '#25bcbd',
          clockFaceTimeInactiveColor: '#4f5757',
        },
    };

我找了，但没有找到解决方案！
