Qr-code challenge

Overall a good solution, very close to the required design.

There is a bit of a difference on the height, which can be resolved by a bit more padding/margin on the paragraph / content;

Possible CSS Optimizations:

• using * as a selector is effective and concise but it move expensive ( in terms of computer resources ) you can put it in the body - those styles are inherited
• user class selectors; Using P or H3 will affect the whole site ( keep in mind for future projects, in this case this works, but you could have done it like .content p {} to be more specific)

Code formatting

• there are unnecessary spaces and new lines
• you can use Prettier and Format on Save ( VS Code >> settings >> search for Formatter ; Prettier should be installed)

Comments

• in real projects, usually its not allowed to leave commented code ( keep in mind for the future )
