Styles overriding

Each Mantine component supports styles overriding for every internal element inside with classes or inline styles. This feature alongside other customization options allows you to implement any visual modifications to components and adapt them to fit almost any design requirements.

Default slider styles

import { Slider } from '@mantine/core';

const marks = [
  { value: 20, label: '20%' },
  { value: 50, label: '50%' },
  { value: 80, label: '80%' },

function Demo() {
  return <Slider defaultValue={40} marks={marks} />;

trackContainerWraps track element
trackSlider track

.mark {
  width: rem(6px);
  height: rem(6px);
  border-radius: rem(6px);
  transform: translateX(rem(-3px)) translateY(rem(-2px));
  border-color: light-dark(var(--mantine-color-blue-1), var(--mantine-color-dark-3));

  &[data-filled] {
    border-color: var(--mantine-color-blue-6);
