How to set the next/image component to 100% height

Question

I have a Next.js app, and I need an image that fills the full height of its container while automatically deciding its width based on its aspect ratio.

I have tried the following:

<Image
    src="/deco.svg"
    alt=""
    layout="fill"
/>

This snippet compiles successfully, but on the frontend, I see the following error:

Error: Image with src "/deco.svg" must use "width" and "height" properties or "unsized" property.

This confuses me because according to the docs, these properties are not required when using layout="fill".

Answer 1

This is what worked for me.

with next/image:

<div style={{width: '100%', height: '100%', position: 'relative'}}>
  <Image
    alt='Mountains'
    src='/mountains.jpg'
    layout='fill'
    objectFit='contain'
  />
</div>

and with next/future/image:

<Image
    fill
    alt='Mountains'
    src='/mountains.jpg'
    sizes='100vw'/>

next/future/image

Answer 2

<img src="/path/to/image.jpg" alt="" title="" />

In NextJS

<Image src="/path/to/image.jpg" alt="" title="" width="100%" height="100%" layout="responsive" objectFit="contain"/>

Answer 3

Here is a way: For example I want to have an image that covers the whole width & height of its container which is a div.

<div className={'image-container'}>
  <Image src={path} layout="fill" className={'image'} />
</div>

And here is the style: (There is a container div that occupies half width & height of viewport & my image will cover it.)

// Nested Styling
.image-container {
    width: 50vw;
    height: 50vh;
    position: relative;

    .image {
        width: 100%;
        height: 100%;
        position: relative !important;
        object-fit: cover; // Optional
    }
}

// Or Normal Styling
.image-container {
    width: 50vw;
    height: 50vh;
    position: relative;
  }
.image-container .image {
    width: 100%;
    height: 100%;
    position: relative !important;
    object-fit: cover; // Optional
}
