Responsive barcode page using css media query and grid to solve it all

Hello there!

Congrats on completing the challenge! ✅

Your solution looks great!

I have a suggestion:

• Since you set grid to the body, but you didn't set the size of the rows, your footer is pushing your card up a little bit. You can prevent that from happening adding this to the body:

grid-template-rows: 90% 1fr;

Then your card will always occupy 90% of the space and the footer will adapt in the remaining space.

I hope it helps!

Other than that, you did an excellent job!

Hi, sorry for the delay! I've just got back from some time off and remembered I promised to give feedback on this to help you lay some better foundations.

I'm afraid this has some substantial problems. I'll list them out one by one and hopefully it will help you refactor this and take the learnings over into other projects.

1. All content should be contained within landmarks. This needs main landmark with the card component inside and a footer landmark for the attribution.
2. The image does not need rapping in an extra div. Try to keep the HTML as simple as possible.
3. The image is extremely important content. Therefore it needs a proper alt description. Remember alt is not code it is content. It must be a human readable description of that image. In this case needs to say what the image is (QR code) and where it goes to (to FrontendMentor.io).
4. The paragraph must be a paragraph not heading. Choosing appropriate HTML elements for the content is an essential skill that you must master.
5. Get into the habit of always including a full modern CSS reset at the start of the styles in every project. Andy Bell or Josh Comeau both have good examples you can look up and use. This will do important things like remove margin from the body and make images display block and max width 100%, as well as lots of other useful things. You always need a reset at the start.
6. There is no reason at all for this card component to be displayed grid. The block elements within it will all stack vertically by default, so unless you're planning to use the gap property to create space between the card's child elements, there is no benefit to use grid or flex in this case.
7. Make sure you understand the difference between padding and margin. The card should have padding to create space inside it and stop it's children from hitting its edges. The child elements within that card should have vertical margins only to create space between them. See https://fedmentor.dev/posts/padding-margin/. Stop setting weird margins on on the left or top of different elements you don't need to do this.
8. Remove all heights and widths from this. You don't need any of them. Instead use a single max-width in rem on the card. That tells it to grow only up until a certain width and no wider, and also tells it it can shrink narrower when it needs to such as on small screens. There is no need at all for a height. Let the browser do its job and decide what height is needed based off the content within the component and the spacings within.
9. Never limit the height of any elements that contain text, including the body. This solution currently breaks because you have set the body height to be 100vh. Instead, change this to min-height. That says "I always want this to be at least 100vh (or svh) tall, but it can grow beyond the viewport height if needed." For example Think of how small 100 VH is when viewed on a small mobile phone in landscape orientation. The body would need to grow taller than that. It's the same principle on the card it doesn't need a height and giving it a height will break it for people who have their text set to be a larger default size.
10. Speaking of text size, you must never use pixels for font size. Instead use rem. This will respond to the users chosen text size. Everything in your solution at the moment is way too small. I can't even read the text it's so small. The style guide states what font size should be used for the body, it just needs to be converted to rem before use in CSS. That is the size that your paragraph should be.
11. The image doesn't need a width or height. All it needs is what's already included in the CSS reset which is max-width 100%. You can make it width 100% if you wish. The image shouldn't need any margins because it is full width of the card anyway. Remember the space from the edges of the card is created by padding on the card.
12. I recommend against using Display grid place content centre on the body. This can cause overflow bugs for people who have a larger tech size and view on a smaller screen. Instead I recommend making the body a flex column. Then if you wish to push the footer down to the bottom of the screen you would simply place flex-grow: 1; on the main landmark.
13. To make sure the component can never touch the screen edges either give the card component a little margin on all sides; or give a wrapping element (like the body) a little padding on all sides.
14. As all the text in the card is centred you can place text-align center on the component itself instead of on individual child elements. They will inherit the text alignment from their parent.
15. I noticed there are several places where you are adding flex properties to non-flex elements which means the CSS declarations do nothing but bloat your CSS. Try and remove everything which is not needed.
16. I'm not sure that you mean to use rem for border radius... It's not "wrong" but it is unusual. Only use rem when you want a property to specifically scale with the users chosen font size. So rem makes a lot of sense for max-width on a component or for font-size declarations but may not be what you want for border width or radius. I expect the image border radius will need to be slightly different than that of the card itself.
17. Do not remove underlines from links. In your attribution there are links that don't look clickable -- this is an accessibility failure. Keep the text decoration and preferably a different colour and a hover style. Also make sure you update the href for your own link. Currently it goes nowhere, but should go to your GitHub or Frontend mentor profile.
18. Check you've linked the font-family correctly. I can't see the actual font link in there, only the google font preconnect links.
19. Move your CSS into a separate linked CSS file.
