Hi, everyone.

I struggle to find the right/correct way of rendering the next/image component in full height (100vh) and respecting the aspect ratio, on all screen sizes.

I want to render a modal when the user clicks on an image, and I want this modal to render full screen height. So, the Image needs to "fill" it's parent container height, but respect the aspect ratio, so that it will leave some space in the width, alternatively crop the top if the image is wide enough to not demand full height.

I fetch the image from Sanity, so I got metadata available to me, such as aspect ratio, original width and height.

For the time being I can't find any other solution than setting the parent
relative**, but then I need to specify the width and height of the container as well it seems. I don't think this will work when I want this to be repsonsive on different screen sizes.

Anyone got some tips for me?

All help appreciated.

You can override the width and height values using tailwind. You need to add a className to the image itself and control its dimensions that way. For example:

import Image from "next/image";

export default function Home() {
  return (
    <div className="h-screen w-screen fixed top-0">
      <Image
        src="/assets/images/aditya-chinchure-5nuRRWZ96eI-unsplash.jpg"
        alt="A view of Vancouver with mountains in the background"
        width={500}
        height={500}
        quality={100}
        sizes="100vw"
        className="bg-slate-600 h-full w-full object-contain"
      />
    </div>
  );
}

I was wondering this the other day. So does this mean that we can use any value for the width and the height?
