Responsive Page using CSS Grid

If you want to make your card responsive with ease you can use this technique:

.card {
width: 90%;
max-width: 37.5rem;
}

On the smaller screens card will be 90% of the parent (here body), but as soon as the card will be 37.5rem (600px) it will lock with this size.

Also to put the card in the center I advise you to use this code snippet:

.container {
display: grid;
place-items: center;
}

Good job and keep going 😁😊😉

Amazing job with this! You’re making fantastic progress. Here are some small tweaks that might take your solution to the next level…

• Using max-width: 100% or min-width: 100% is more responsive than just width: 100% because they allow elements to adjust better to different screen sizes. To learn more, check out this article: responsive-meaning.

• Developers should avoid using pixels (px) because they are a fixed size and don't scale well on different devices. Instead, use rem or em, which are relative units that adjust based on user settings, making your design more flexible, responsive, and accessible. For more information check out this, Why font-size must NEVER be in pixels or this video by Kevin Powell CSS em and rem explained.- Another great resource for px to rem converter.

• For future project, You could downloading and host your own fonts using @font-face improves website performance by reducing external requests, provides more control over font usage, ensures consistency across browsers, enhances offline availability, and avoids potential issues if third-party font services become unavailable.

• Line height is usually unitless to scale proportionally with the font size, keeping text readable across different devices. Best practice is to use a unitless value like 1.5 for flexibility. Avoid using fixed units like px or %, as they don't adapt well to changes in font size or layout.

You’re doing fantastic! I hope these tips help you as you continue your coding journey. Stay curious and keep experimenting—every challenge is an opportunity to learn. Have fun, and keep coding with confidence! 🌟

Looks good. You might wanna use min-height, max-width instead of height and width and em-rem units for margins, paddings and text sizes etc.
