Replace<div class="qr-card ">with the main tag and <div class="attribution"> with the footer tag to fix the accessibility issues. click here for more on web-accessibility and semantic html
To center .card on the page using flexbox, replace the height in the body with min-height: 100vh.
For a responsive content, there is no need to give .qr-card a height value rather replace the width with max-width
and give the img a max-width of 100% and a border-radius value.
There is no need to style .qr-img .
Give .content a margin value for all the sides, text-align: center and a font-size of 15px which is 0.9375rem, this will be the font-size of both p and h1. Give p a margin-top or h1 a margin-bottom value for the space between the text.
Use relative units like rem or em as unit for the padding, margin, width values and preferably rem for the font-size values, instead of using px which is an absolute unit. For more on CSS units Click here
