Style props

With style props, you can add inline styles to any Mantine component. Style props add styles to the root element, if you need to style nested elements, use Styles API instead.

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

function Demo() {
  return (
    <Box mx="auto" maw={400} c="blue.6" bg="#fff">
      Your component
    </Box>
  );
}

Theme values

Some style props can reference values from theme, for example mt will use theme.spacing value if you set xs, sm, md, lg, xl:

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

// margin-top: theme.spacing.xs
<Box mt="xs" />

// margin-top: theme.spacing.md * -1
<Box mt="-md" />

// margin-top: auto
<Box mt="auto" />

// margin-top: 1rem
<Box mt={16} />

// margin-top: 5rem
<Box mt="5rem" />

In c and bg props you can reference colors from theme.colors:

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

// color: theme.colors.blue[theme.fn.primaryShade()]
<Box c="blue" />

// background: theme.colors.orange[1]
<Box bg="orange.1" />

// color: if colorScheme is dark `var(--mantine-color-dark-2)`,
// if color scheme is light `var(--mantine-color-gray-6)`
<Box c="dimmed" />

// color: if colorScheme is dark `var(--mantine-color-white)`,
// if color scheme is light `var(--mantine-color-black)`
<Box c="bright" />


// background: #EDFEFF
<Box bg="#EDFEFF" />

// background: rgba(0, 34, 45, 0.6)
<Box bg="rgba(0, 34, 45, 0.6)" />

Responsive styles

You can use object syntax to add responsive styles with style props. Note that responsive style props are less performant than regular style props, it is not recommended to use them in large lists of elements.

Box with responsive style props
import { Box } from '@mantine/core';

function Demo() {
  return (
    <Box
      w={{ base: 200, sm: 400, lg: 500 }}
      py={{ base: 'xs', sm: 'md', lg: 'xl' }}
      bg={{ base: 'blue.7', sm: 'red.7', lg: 'green.7' }}
      c="#fff"
      ta="center"
      mx="auto"
    >
      Box with responsive style props
    </Box>
  );

Responsive values are calculated the following way:

  • base value is used when none of breakpoint values are applied
  • xs, sm, md, lg, xl values are used when the viewport width is larger that the value of corresponding breakpoint specified in theme.breakpoints
import { Box } from '@mantine/core';

<Box w={{ base: 320, sm: 480, lg: 640 }}} />

In this case the element will have the following styles:

/* Base styles added to element and then get overwritten with responsive values */
.element {
  width: 20rem;
}

/* 48em is theme.breakpoints.sm by default */
@media (min-width: 48em) {
  .element {
    width: 30rem;
  }
}

/* 75em is theme.breakpoints.lg by default */
@media (min-width: 75em) {
  .element {
    width: 40rem;
  }
}
