QR card

Some recommendations regarding your code could be of interest to you.

• In order to center the card easily and correctly, you'd better add flexbox and min-height: 100vh to the body

body {
   display: flex;
   justify-content: center;
   align-items: center;
   min-height: 100vh;
}

• After adding them, you can remove margin-top and display: inline-block from the .card because you don't need them anymore

.card {
   /* display: inline-block; */
   /* margin-top: 150px; */
}

Hope I am helpful. :)

Well done jsr7k, like you I have just done this as my very first and did a similar job. I am also an older newbie. I am still trying to figure out the centring part of it, but I think you did well.

Good Job for a first.

However the size is off, if you center the design vertically it makes it easier to compare the sizes. If you redo this challenge, I think you'll nail it!
