Resize a Next.js Image component inside a div

Question

I try to make a section that contains on a side some text and on the other side an Image that should be responsive (i.e. that becomes smaller when the window's size is also becoming smaller).

Using a simple <img src="/myimage.extension" alt="describe my image" /> does work perfectly. But as soon as I use the Next.JS Image component (in order to benefit from the optimization it does), it breaks the responsiveness.

Indeed, to make a kind of hero section with a responsive image I got this code (working perfectly fine):

<>
<div className={"h-screen py-0 py-20 text-center bg-blue-100 text-dark-blue"}>
  <div
    className={"flex flex-col items-center justify-center h-full md:flex-row app-container md:justify-between"}>
    <div>
      <h1 className={"text-red-400"}>With the Image component</h1>
      <p>It doesn't resize on the size of the viewport</p>
    </div>
    <div className={"relative"}>
      <svg
        className={"absolute right-0 z-50 hidden w-1/2 sm:block"}
        css={css`top: 25px;left: 25px;`}
        xmlns="http://www.w3.org/2000/svg" viewBox="0 0 674 674"
      >
        <circle id="Ellipse_8" cx="337" cy="337" r="337" fill="#e23b58"/>
      </svg>
      <img
        src={"/image.jpg"}
        alt={"Some image description"}
      />
    </div>
  </div>
</div>
</>

Then, replacing the img tag by an Image component breaks the responsiveness: the image never becomes smaller. It keeps its size.

<>
  <div className={"h-screen py-0 py-20 text-center bg-green-100 text-dark-blue"}>
    <div
      className={"flex flex-col items-center justify-center h-full md:flex-row app-container md:justify-between"}>
      <div>
        <h1 className={"text-red-400"}>With the Image component</h1>
        <p>It doesn't resize on the size of the viewport</p>
      </div>
      <div className={"relative"}>
        <svg
          className={"absolute right-0 z-50 hidden w-1/2 sm:block"}
          css={css`top: 25px;left: 25px;`}
          xmlns="http://www.w3.org/2000/svg" viewBox="0 0 674 674"
        >
          <circle id="Ellipse_8" cx="337" cy="337" r="337" fill="#e23b58"/>
        </svg>
        <Image
          src={"/image.jpg"}
          alt={"Some image description"}
          width={1103}
          height={628}
        />
      </div>
    </div>
  </div>
</>

You can see what's happening on this Sandbox. I'm looking for a way that enable me to control precisely how the Image component would be positioned.

The problem is not in the Image component. It's related to the styles applied to the div container.

If you remove items-center from the classes in lines 18-22 you will see that the image is resizing:

<div className={"flex flex-col items-center justify-center ...}>

Change to:

<div className={"flex flex-col justify-center ...}>

Yeah you're right. There is also an issue that appears then on the vertical align that can be handled using a higher flex container.
