site qr code usando html e css

Hello @jeanpablo64!

Great Job solving the challenge mate congrats 🎉

Some suggestions for improvements.

For the font-size it's is better to use rems and ems but px for this project is no big deal.

font-size: 13px;

• i see you using pixels for many elements, never use pixels for font-sizes in any element, here's why:

• Certain font-related CSS properties will render your site completely inaccessible if their value is declared using pixels even once.

Which properties are affected?

All of these properties must never ever be declared in pixels:

• font-size
• line-height
• letter-spacing

If you've used pixels to define any of the above style properties, these will not respect the user's font size preferences!

• You should use ems, and rems for font-sizes would be better
