Html – Is there a way to flex field generate by for loops?

This is my code that generates fields using a for loop. I’m expecting the email and phone number fields to be displayed side by side, but instead, they are stacked on top of each other. I believe this issue is due to the for loop. Is there a way to make the email and phone number fields appear side by side while keeping the other form fields vertical?

Here is my code.

<form *ngIf="dynamicForm" [formGroup]="dynamicForm" >
        <div *ngFor="let field of formData.fields">
          <ng-container [ngSwitch]="field.type">
            <div *ngSwitchCase="'text'" [ngClass] = "{'two-flex-items':false,'form-group':true}">
              <input [formControlName]="field.name" [id]="field.name" type="text" [placeholder]="field.placeholder"
                [required]="field.required">
            </div>
            <div *ngSwitchCase="'email'">
              <div class="form-group">
                <div>
                  <input [formControlName]="field.name" [id]="field.name" type="email" [placeholder]="field.placeholder"
                    [required]="field.required">
                </div>
              </div>
            </div>
            <div *ngSwitchCase="'tel'">
              <div class="form-group">
                <div >
                  <input [formControlName]="field.name" [id]="field.name" type="tel" [placeholder]="field.placeholder"
                    [required]="field.required">
                </div>
              </div>
            </div>
            <div *ngSwitchCase="'textarea'" [ngClass] = "{'two-flex-items':false,'form-group':true}">
              <input [formControlName]="field.name" [id]="field.name" type="textarea" [placeholder]="field.placeholder"
                [required]="field.required">
            </div>
            <div *ngSwitchCase="'select'" [ngClass] = "{'two-flex-items':false,'form-group':true}">
              <select [formControlName]="field.name" [id]="field.name" [required]="field.required">
                <option value="" disabled selected>{{field.placeholder}}</option>
                <option *ngFor="let option of field.options" [value]="option.value">
                  {{option.placeholder}}
                </option>
              </select>
            </div>
          </ng-container>

          <div *ngIf="dynamicForm.get(field.name).invalid && dynamicForm.get(field.name).touched">
            {{field.name}} is required
          </div>
        </div>
        <button type="submit" (click)="onSubmit()" [disabled]="dynamicForm.invalid"
          [ngStyle]="{'background-color': formData.theme.primaryColor}">
          Submit
        </button>
      </form>

This is the scss

.form-group{
    width: 100%;
    input,textarea,select{
        width: 100%;
        outline: none;
        border: 1px solid #e6e6e6;
        padding: 10px;
        font-size: 14px;
        border-radius: 4px;

        &::placeholder{
            color: #cecdcd;
        }

        &:focus{
            border:1px solid#afafaf;
        }
    }


    .error-msg{
        color: red;
        margin-top: 3px;
        padding: 3px 10px;
    }
}
.form-container{
    background-color: white;
    border-radius: 6px;
    box-shadow: 0px 0px 10px rgba(0, 0, 0, 0.068);
    margin: 20px;
    padding: 20px;
    padding-top: 40px;
    display: flex;
    flex-direction: column;
    gap: 20px;
}
.two-flex-items {
    display: flex;
    gap: 20px; /* Adjust the gap between inputs */
  }
