Theme

Mantine theme is an object where your application's colors, fonts, spacing, border-radius and other design tokens are stored. You can either create your own theme object or use themes that provide from refine. There are two types of themes: LightTheme and DarkTheme. LightTheme tend to have dark text on a light background, while DarkTheme have light text on a dark background. Theme provides a way to your app's design to meet them.

Refer to the Mantine documentation for more information about theme object. →

Theme customization

<MantineProvider/> component can be used to change theme. It is not required if you decide to use the default theme. You can also use LightTheme and DarkTheme provided by refine.

    );

Overriding the refine themes

You can override or extend the default refine themes. You can also create your own theme. Let's see how to do this.

http://localhost:3000

import { Refine } from "@refinedev/core";
import routerProvider from "@refinedev/react-router-v6";
import dataProvider from "@refinedev/simple-rest";
import {
    Layout,
    notificationProvider,
    ErrorComponent,
    LightTheme,
} from "@refinedev/mantine";
import { MantineProvider, Global } from "@mantine/core";
import { NotificationsProvider } from "@mantine/notifications";

import { BrowserRouter, Routes, Route, Outlet } from "react-router-dom";

import { PostCreate, PostEdit, PostList } from "./pages";

const App = () => {
    return (
        <MantineProvider
            theme={{
                ...LightTheme,
                colors: {
                    primary: [
                        "#ECF9F8",
                        "#C9EEEC",
                        "#A6E2E1",
                        "#84D7D5",
                        "#61CCC9",
                        "#3EC1BD",
                        "#329A97",
                        "#257471",
                        "#194D4B",
                        "#0C2726",
                    ],
                },
            }}
            withNormalizeCSS
            withGlobalStyles
        >
            <Global styles={{ body: { WebkitFontSmoothing: "auto" } }} />
            <NotificationsProvider position="top-right">

                    <Refine

                        dataProvider={dataProvider(
                            "https://api.fake-rest.refine.dev",
                        )}
                        notificationProvider={notificationProvider}
                        Layout={Layout}
                        resources={[
                            {
                                name: "posts",

                            },
                        ]}
                    >
                        <Routes>
                            <Route element={(
                                <Layout>
                                    <Outlet />
                                </Layout>
                            )}>
                                <Route path="posts">

                        </Routes>
                    </Refine>
                </BrowserRouter>
            </NotificationsProvider>
        </MantineProvider>
    );
};

Theme switching

You can switch between themes as Mantine mentioned in its documentation. You can see an example of using local storage to store the theme below.

http://localhost:3000

import { Refine } from "@refinedev/core";
import routerProvider from "@refinedev/react-router-v6";
import dataProvider from "@refinedev/simple-rest";
import {
    Layout,
    ErrorComponent,
    notificationProvider,
    LightTheme,
    DarkTheme,
} from "@refinedev/mantine";
import { NotificationsProvider } from "@mantine/notifications";
import {
    MantineProvider,
    Global,
    useMantineColorScheme,
    Header as MantineHeader,
    Group,
    ActionIcon,
    ColorScheme,
    ColorSchemeProvider,
} from "@mantine/core";
import { useLocalStorage } from "@mantine/hooks";

import { BrowserRouter, Routes, Route, Outlet } from "react-router-dom";

import { IconSun, IconMoonStars } from "@tabler/icons";

import { PostCreate, PostEdit, PostList } from "./pages";

const Header = () => {
    const { colorScheme, toggleColorScheme } = useMantineColorScheme();
    const dark = colorScheme === "dark";

    return (
        <MantineHeader height={50} p="xs">
            <Group position="right">
                <ActionIcon
                    variant="outline"
                    color={dark ? "yellow" : "primary"}
                    onClick={() => toggleColorScheme()}
                    title="Toggle color scheme"
                >
                    {dark ? <IconSun /> : <IconMoonStars />}
                </ActionIcon>
            </Group>
        </MantineHeader>
    );
};

const App = () => {
    const [colorScheme, setColorScheme] = useLocalStorage<ColorScheme>({
        key: "mantine-color-scheme",
        defaultValue: "light",
        getInitialValueInEffect: true,
    });

    const toggleColorScheme = (value?: ColorScheme) =>
        setColorScheme(value || (colorScheme === "dark" ? "light" : "dark"));

    return (
        <ColorSchemeProvider
            colorScheme={colorScheme}
            toggleColorScheme={toggleColorScheme}
        >
            <MantineProvider
                theme={colorScheme === "dark" ? DarkTheme : LightTheme}
                withNormalizeCSS
                withGlobalStyles
            >
                <Global styles={{ body: { WebkitFontSmoothing: "auto" } }} />
                <NotificationsProvider position="top-right">
                    <BrowserRouter>
                        <Refine

                            )}
                            notificationProvider={notificationProvider}
                            resources={[
                                {
