26 Feb 20262 minutes to read

The spin button icons can be customized by overriding the e-spin-up and e-spin-down CSS classes. The following example demonstrates how to change the spin up and down icons using custom CSS.

  .e-numeric .e-input-group-icon.e-spin-up:before {
    content: "\e823";
    color: rgba(0, 0, 0, 0.54);
  }
  .e-numeric .e-input-group-icon.e-spin-down:before {
    content: "\e934";
    color: rgba(0, 0, 0, 0.54);
  }

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { NumericTextBoxModule } from '@syncfusion/ej2-angular-inputs'



import { Component } from '@angular/core';

@Component({
imports: [
         NumericTextBoxModule
    ],


standalone: true,
    selector: 'app-root',
    // specifies the template string for the NumericTextBox component
    // sets value to the NumericTextBox
    template: `
            <ejs-numerictextbox value='10'></ejs-numerictextbox>
            `

    }
