Qr code component hub HTML, CSS and Bootstrap learning

Hello Devalito67, how are you? Welcome to the community of front-end mentors! I truly loved your project's outcome, however I have some advice that I hope you'll find useful:

A document ought to have one primary landmark, and the absence of a main tag around the page's primary content is the root of this issue. On this page, there is no other element that is more important than the one that this challenge is based on, so to solve it, wrap all the content in the'main' tag.

It's always a good idea to pay close attention to the proper use of semantic html elements because they are crucial for screen reader users to understand what the main content of the page is in the case of the'main' tag!

Consider using rem for font size .If your web content font sizes are set in absolute units, such as pixels, the user will not be able to re-size the text or control the font size based on their needs. Relative units “stretch” according to the screen size and/or user’s preferred font size, and work on a large range of devices.

if you want to continue coding with px, you can download a very useful extension in vscode, it converts px to rem! link -> px to rem

The remainder is excellent.

I hope it's useful. 👍

In this challenge design is essentially the same for screens width 375px and 1440 px In later challenges layout could be quite different for different width screens. and ussualy this is adressed with css media queries and mobile-first approach Also this desing has a light shadow, you can add it with css box-shadow
