Describe the Bug

Images with the responsive layout are not displayed on the page if put inside a flexbox container.

Expected Behavior

Responsive images should be visible.

To Reproduce

0. Create an app through:

npx create-next-app next-image-flexbox-bug
cd next-image-flexbox-bug

1. Create a Next page with the following code:

// pages/next-image-flexbox-bug.js
import Image from 'next/image';

export default function NextImageFlexboxBug() {
  return (
    <div style={{display: 'flex'}}>
      <Image
        src="/sunset1.jpg" 
        alt="Sunset" 
        width={600} 
        height={450} 
        layout="responsive"
      />
    </div>
  )
}

2. Run the server:

yarn dev

3. Open in Chrome:

http://localhost:3000/next-image-flexbox-bug

4. Nothing is displayed on the page (the white screen).

An update on this issue:
I tried setting display:grid for the container. It works, but if I add justify-content:center, it crashes the Image component in the same way.

This is a known issue for layout="responsive".

There's a proposal to add layout="flex-item" to solve this use case in #18637.

In the meantime, you can use a wrapper <div style={{ width: "100%" }}> around the image so that becomes the flex item.

import Image from "next/image";

export default function Home() {
  return (
    <div style={{ display: "flex" }}>
      <div style={{ width: "100%" }}>
        <Image
          src="/sunset1.jpg"
          alt="Sunset"
          width={600}
          height={450}
          layout="responsive"
        />
      </div>
    </div>
  );
}

Thank you very much @styfle for your reply and the temporary solution you suggested.
Looking forward to a Next update with the new layout styles.

Tested with the latest 11.1.0. The bug still persists.

PR #28221 was released to the canary channel, it just prints a warning.

You can try it out with yarn add next@canary, thanks!

[kkomelin]

Thanks @styfle but, unfortunately, I don't see any related warnings in the browser or server console.

[styfle]

I tried the following code and removed the <div> wrapper hack and it prints a warning with next dev in Chrome: #27644 (comment)

Can you provide an example that doesn't print the warning?
