Usage

Overlay takes 100% of width and height of parent container or viewport if fixed prop is set. Set color and opacity props to change Overlay background-color. Note that opacity prop does not change CSS opacity property, it changes background-color. For example, if you set color="#000" and opacity={0.85} background-color will be rgba(0, 0, 0, 0.85):

import { useState } from 'react';
import { Button, Overlay, Image, AspectRatio } from '@asuikit/core';


function Demo() {
  const [visible, setVisible] = useState(true);
  return (
    <>
      <AspectRatio ratio={16 / 9} maw={400} mx="auto">
        <Image src="https://images.unsplash.com/photo-1618359057154-e21ae64350b6?ixlib=rb-4.0.3&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=720&q=80" />
        {visible && <Overlay color="#000" opacity={0.85} />}
      </AspectRatio>
      <Button onClick={() => setVisible((v) => !v)} fullWidth maw={200} mx="auto" mt="xl">
        Toggle overlay
      </Button>
    </>
  );
}

Gradient

Set gradient prop to use background-image instead of background-color. When gradient prop is set, color and opacity props are ignored.

import { useState } from 'react';
import { Button, Overlay, Image, AspectRatio } from '@asuikit/core';


function Demo() {
  const [visible, setVisible] = useState(true);
  return (
    <>
      <AspectRatio ratio={16 / 9} maw={400} mx="auto">
        <Image src="https://images.unsplash.com/photo-1618359057154-e21ae64350b6?ixlib=rb-4.0.3&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=720&q=80" />
        {visible && (
          <Overlay
            gradient="linear-gradient(145deg, rgba(0, 0, 0, 0.95) 0%, rgba(0, 0, 0, 0) 100%)"
            opacity={0.85}
          />
        )}
      </AspectRatio>
      <Button onClick={() => setVisible((v) => !v)} fullWidth maw={200} mx="auto" mt="xl">
        Toggle overlay
      </Button>
    </>
  );
}

Blur

Set blur prop to add backdrop-filter: blur({value}) styles Note that backdrop-filter is not supported in all browsers.

import { useState } from 'react';
import { Button, Overlay, Image, AspectRatio } from '@asuikit/core';


function Demo() {
  const [visible, setVisible] = useState(false);


  return (
    <AspectRatio ratio={16 / 9} maw={400} mx="auto">
      <Image
        src="https://images.unsplash.com/photo-1546527868-ccb7ee7dfa6a?ixlib=rb-4.0.3&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=720&q=80"
        onClick={() => setVisible(false)}
      />
      {!visible && (
        <Overlay blur={15} center>
          <Button color="red" radius="xl" onClick={() => setVisible(true)}>
            NSFW, click to reveal
          </Button>
        </Overlay>
      )}
    </AspectRatio>
  );
}

Polymorphic component

Overlay is a polymorphic component, set component prop to change root element:

import { Overlay } from '@asuikit/core';
import { Link } from 'react-router-dom';


function Demo() {
  return (
    <>
      <Overlay<'a'> component="a" href="#" />
      <Overlay<typeof Link> component={Link} to="/hello" />
    </>
  );
}
