What did you find difficult while building the project?

This was my first time using tailwind and next.js with the new app router.
I spend a decent amount of time reading the docs for project layout/installation even though this project was pretty simple.

Which areas of your code are you unsure of?

I did place the code section in the provided project files as a "footer" here:

function Footer() {
  return (
    <div className="sticky bottom-0 text-center">
      Challenge by{" "}
      <a href="https://www.frontendmentor.io?ref=challenge" target="_blank" className="font-bold underline hover:decoration-2">
        Frontend Mentor
      </a>
      . Coded by <a href="https://www.github.com/njpoli" className="font-bold underline hover:decoration-2">njpoli</a>.
    </div>
  );
}

I placed my footer in the page.tsx file like so:

export default function Page() {
  return (
    <>
      <div className="flex flex-col justify-center items-center h-screen">
        <QRCode />
      </div>
      <Footer />
    </>
  );
}

However, this created a small scroll bar even though the footer is correctly sticking to the bottom of the viewport. When I place the footer inside of the div with the QRCode component, it doesnt go to the bottom of the viewport, it is directly under the QRCode component. How can I have the footer stick to the bottom without creating a scrollbar?

Do you have any questions about best practices?

Should the footer contain the sticky css property or does that belong in the parent component? Any other tips/suggestions welcome as well.

Hello ✌, well done on finishing the challenge. The scrollbar appeared because you used "h-screen" class which gave the whole card part span 100% viewport height, and therefore, the attribution part is going to make more space. And even with position: sticky, it still stays as a part of the website flow and occupies more space.

My solution for this is to give the position of attribution part absolute or fixed, that way, it won't stay as a part of the website flow, and won't create a scrollbar like so:

.absolute {
    position: absolute;
   / * centering the attribution texts */
    left: 50%;
    transform: translateX(-50%);
}

Hope you find my comment useful 😁

@chinh1402 Thanks for the assistance, I was able to get it working with position absolute. I didn't realize that a sticky component is still a part of the normal website flow, unlike absolute positioning. I was probably doing it wrong, but I couldn't get your solution working for my footer component. This is what ended up working for me.

Moving the footer inside of the wrapper div:

      <div
        className="flex flex-col justify-center items-center h-screen"
        role="main"
      >
        <QRCode />
        <Footer />
      </div>

And using tailwindcss classes which in css is what I believe translates to:

.footer {
    position: absolute;
    bottom: 0px;
}

My actual code here:

function Footer() {
  return (
    <div className="absolute bottom-0" role="contentinfo">
      Challenge by{" "}
      <a href="https://www.frontendmentor.io?ref=challenge" target="_blank" className="font-bold underline hover:decoration-2">
        Frontend Mentor
      </a>
      . Coded by <a href="https://www.github.com/njpoli" className="font-bold underline hover:decoration-2">njpoli</a>.
    </div>
  );
}

Thanks for your help!
