Customize the limits in EJ2 JavaScript Range slider control
15 May 202312 minutes to read
Slider appearance can be customized via CSS. By overriding the slider CSS classes, the slider limit bar can be customized. Here, the limit bar is customized with different background color. By default, the slider has class e-limits for limits bar. You can override the class with our own color values as given in the following code snippet.
.e-slider-container.e-horizontal .e-limits {
background-color: rgba(69, 100, 233, 0.46);
}
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
import { Slider, NumericTextBox, ChangeEventArgs } from '@syncfusion/ej2-inputs';
import { CheckBox, ChangeEventArgs as CheckBoxChange } from '@syncfusion/ej2-buttons';
