Fylo storage challenge solution with CSS Flex, Grid, RWD & animations

It looks good Jan!... You have accessibility issues that need to fix.

• Document should have one main landmark, Contain the component with <main>.

<main>
   <section class="fylo">
      //...
   </section>
</main>

• Buttons must have discernible text, Set the attribute aria-label to describe the button... Example:

<button class="btn" aria-label="File Upload">
   //...
</button>

Hope this is helpful to you... Keep coding👍
