How to use Tailwind CSS with Next.js Image

Question

I am trying to use Tailwind CSS in an Next.js project but I cant't use my Tailwind classes with Next.js Image component.

Here's my code:

<Image
    src={img.img}
    alt="Picture of the author"
    width="200"
    height="200"
    className="bg-mint text-mint fill-current"
></Image>

I want to use Tailwind classes instead of the height and width property of the Next.js Image. But I can't because it throws me an error. Also, unsized property throws another error saying it's deprecated. Is there any solution?

Here is the error if I don't use the height and width property.

When I use the layout='fill' property it shows only one picture. And if I use the unsized property, then the following error is shown.

Solution

There’s a discussion and related example over at the Next.js GitHub project. It sounds like that example achieves what you want to do. tl;dr:

<div className="h-64 w-96 relative"> // "relative" is required; adjust sizes to your liking
  <Image
    src={img.img}
    alt="Picture of the author"
    layout="fill" // required
    objectFit="cover" // change to suit your needs
    className="rounded-full" // just an example
  />
</div>

The image will preserve its original aspect ratio and fill / cover (or whatever object-fit you chose) the size of the outer div, which you can set using Tailwind classes. Other styles, like rounded corner, can be applied to the Image.
