Solution retrospective


That was quite a tough challenge, but I think I learned quite a lot (working with setInterval(), setTimeout() in JS; adding animation via JS, etc.)!

The most difficult part was to animate the cards. I struggled for some time with css and then tortured myself with js, but eventually it worked 😅 (There's a bug where numbers kind of skew a pixel or two every time they flip. I've tried really hard to get rid of it, but the only solution was to change the width/height of the card, which worked only for the desktop design. P.S. I tried all kinds of length units, like px, rem, %, vw, etc.).

In terms of functionality, you can do the following:

  • Press "Space" key to pause/resume the timer;
  • Press "Enter" key to see what happens at the end of the countdown (there's some extra animation I added);
  • Click social-media links to refresh the page and therefore restart the timer.

As always, any feedback is welcome!

Happy coding, everyone! 😉

    Hello Bonrey,

    Sweet Job ! I like yours a lot, I saw a different person's solution and only the numbers moved. You made the animation were the little 'flaps' move. Also I like the animation at the end of the countdown.

    Keep Coding!

    Hi, Bonrey! 👋

    Amazing work on this challenge! 👏 Animating the countdown cards can definitely be tricky, but I think you've done a pretty nice job on that! 👍

    I really like the extra features you added and it's great to hear you learned a lot during this challenge (I always learn new things when I complete challenges, too). 😀

    Everything else looks good and is responsive. 👏

    A minor suggestion might be to make sure the background image of the mountains scales to fit the entire screen on extra-large screens (currently, there's just some empty space to the left side of it). 😉

    Keep coding (and happy coding, too)! 😁

    Hi Bonrey !

    Wow, well done for your project 😃

    I did it too but I clearly did not manage to make the animations on the maps and I admit that I did not have the patience to do it either.

    Well done for the features 👍

    good continuation !

How does the accessibility report work?

When a solution is submitted, we use axe-core to run an automated audit of your code.

This picks out common accessibility issues like not using semantic HTML and not having proper heading hierarchies, among others.

This automated audit is fairly surface level, so we encourage to you review the project and code in more detail with accessibility best practices in mind.

How does the CSS report work?

When a solution is submitted, we use stylelint to run an automated check on the CSS code.

We've added some of our own linting rules based on recommended best practices. These rules are prefixed with frontend-mentor/ which you'll see at the top of each issue in the report.

The report will audit 1st-party linked stylesheets, and styles within <style> tags.

How does the HTML validation report work?

When a solution is submitted, we use html-validate to run an automated check on the HTML code.

The report picks out common HTML issues such as not using headings within section elements and incorrect nesting of elements, among others.

Note that the report can pick up “invalid” attributes, which some frameworks automatically add to the HTML. These attributes are crucial for how the frameworks function, although they’re technically not valid HTML. As such, some projects can show up with many HTML validation errors, which are benign and are a necessary part of the framework.
