Customize slider ticks label in Angular Range Slider component

22 Jul 2021 / 2 minutes to read

Slider view can be customized via CSS. By overriding the slider CSS classes, you can customize the ticks. The ticks in slider allows you to easily identify the current value/values of the slider. It contains smallStep and largeStep. By default, slider has class e-tick for slider ticks. You can override the class as per your requirement. Refer to the following code snippet to render ticks.

.e-scale .e-tick.e-custom::before {
    content: '\e967';
    position: absolute;
}

Here, the color for rendered ticks has been applied through nth-child(child_number). The color is applied to the value of the child_number in the slider.

.e-scale :nth-child(1)::before {
    color: red;
}
