QR code component

Hi, the goal of the exercise its trying to approach the design as much as possible, that's why i want to give u some feedback.

-Most important: Try to resize your web card page, and you will notice everything goes bad so, my advice its to re-do the visual BASED on the mobile design first principals(part of the excercise)

-Start the style-file code with this, to improve performance and web window usage (removing margins and unnecessary items by default in the browsers)

*{ box-sizing: border-box; margin: 0; padding: 0; }
