Sass, js(vanilla), BEM

Hello! It's an amazing work, really! 😲

But here are some suggestions:

• Place your .container inside a main landmark tag.
• Instead of so many arrays (dailyCurrent, dailyPrevious, weeklyCurrent, ...), you can use array to store objects. For example:

const dailyData = [
  {
    current: 0,
    previous:0
  },
  ...
]

• You can try using template for elements such as those cards 😉. (So the JS wouldn't be cluttered with createElement). Although you will still need to querySelector each class inside to set the values. 😂
• Instead of card0, card1, ..., why not use an array to store them? 🤔 This way, your displayCards() and removeCards() lines of code will be much lesser and less repetition.

Wow, this is really incredible! The design is indistinguible from the original and the responsive is magnificent, you use the grid layout so well. I really like this so much, please keep going 💖. And for the dots... maybe you can put a mini menu who cover the card with fake options? You can use addEvenListener click and mouseover.
