QR code component using CSS custom properties and flex box

This is my solution to the QR code component challenge. I decided to include a CSS reset to set up some default styles. I looked into Andy Bell's one for this. This reset contains styles referring to tags that I did not use in this challenge. For example:

/* Inherit fonts for inputs and buttons */
input,
button,
textarea,
select {
  font: inherit;
}

Should I leave out the default styles that are not relevant to the styling of the QR code component or is it better to always include the entire CSS reset?

I am looking forward to your feedback and suggestions!
