Solution retrospective

What are you most proud of, and what would you do differently next time?

I learned how to position a column vertically and horizontally center by using position absolute. Mobile responsive with breakpoints and using media queries, em and rem instead of pixels. Also importing a font from Google fonts.

What challenges did you encounter, and how did you overcome them?

I was clueless when I m trying to center a div in the middle.

What specific areas of your project would you like help with?

Anything else would you guys want me to improve for a starter like me on my first project.

    Hello there 👋. Good job on completing the challenge !

    I am not an expert but I have some suggestions about your code that might interest you.

    HTML 📄:

    • Use the <main> tag to wrap all the main content of the page instead of the <div> tag. With this semantic element you can improve the accessibility of your page.
    • Use the <footer> tag to wrap the footer of the page instead of the <div class="attribution">. The <footer> element contains information about the author of the page, the copyright, and other legal information.
    • Since this component involves scanning the QR code, the image is not a decoration, so it must have an alt attribute. The alt attribute should explain its purpose. e.g. QR code to frontendmentor.io

    CSS 🎨:

    • Instead of using pixels in font-size, use relative units like em or rem. The font-size in absolute units like pixels does not scale with the user's browser settings. This can cause accessibility issues for users who have set their browser to use a larger font size. You can read more about this here 📘.
    • Use min-height: 100vh instead of height: 100vh. The height property will not work if the content of the page grows beyond the height of the viewport.
    • Setting the width of the component with a percentage or a viewport unit will behave strangely on mobile devices or large screens. You should use a max-width of 320px or another value to make sure that the component will have a maximum width of 320px on any device, also remove the width property with a vw value.
    • Setting a defined height for the card component is not recommended. The content should define the component height, otherwise, it will not be allowed to extend beyond your specifications. Alternatively, you can use min-height.
    • In any device between 767px and 1024px wide there is no style, because I use two media query with min-width and max-width there are no styles that apply to tablets.
    • Avoid setting margins, width and height padding with percentage as this can be problematic when trying to create a consistent layout. Use units such as rem, em or pixels instead.

    I hope you find it useful! 😄 Above all, the solution you submitted is great!

    Happy coding!
