How can I style a calculator in Ionic?

Question

css

Greetings! I have such a problem, I started to style the project made on Ionic and got stuck on styling the calculator. The project is made by another person, I just add styles and change the layout structure a little if necessary. This data selection is done via ion-picker, a ready-made picker template.
Tell me, how can I style such a calculator as in the picture?

You can guess, maybe you will throw some idea, I will finalize it.
Layout code:

<ion-header>
  <ion-toolbar>
     <ion-buttons slot="start">
      <ion-back-button defaultHref="{{defRef}}" icon="./assets/img/login/arrow-back.svg"></ion-back-button>
    </ion-buttons>
    <ion-title class="header-title">{{header}}</ion-title>
  </ion-toolbar>
</ion-header>

<ion-content fullscreen>
   <ion-list class="flex-sb" lines="none"> 
      <ion-list-header *ngIf="defRef == 'person-job'" >
          <ion-label>Хочу занять</ion-label>    
          <ion-label style="display: block;" text-wrap>{{credit_data.sum_value}} руб. на {{credit_data. day_value}} дней</ion-label>     
      </ion-list-header> 
      
       <credit-picker [credit_data]="credit_data" ></credit-picker>  
          <ion-button *ngIf="defRef != 'person-job'" class="button-global" expand="block"  (click)="takeCredit()">Получить деньги</ion-button> 
          <ion-button *ngIf="defRef == 'person-job'" expand="block"  color="secondary"  (click)="submitCredit()">Отправить заявку</ion-button>   
    </ion-list>

</ion-content>

The code that is already generated in the browser for the calculator:

<credit-picker _ngcontent-ntx-c8="" _nghost-ntx-c9="" ng-reflect-credit_data="[object Object]">
  <pickerview _ngcontent-ntx-c9="" ng-reflect-data="[object Object],[object Object" ng-reflect-cascade="false" ng-reflect-model="7000 руб,на,20 дней" class="ng-untouched ng-pristine ng-valid">

This is what the calculator looks like now:
