Mencipta ruang antara kad dalam gelangsar: bagaimana untuk menentukan margin?

Question

Saya cuba mencipta gelangsar tetapi kad di dalamnya tidak mempunyai ruang sama sekali. Saya cuba menambah margin di antara mereka tetapi itu tidak berfungsi.

Bolehkah anda membantu saya mengetahui di mana saya telah kacau? Terima kasih terlebih dahulu.

Memandangkan anda meletakkan kad secara manual*, cuma tambahkan jurang kali indeks pada setiap nilai transformasi.

const cardGap = 8; 
card.style.transform = `translateX(${100 * (index - currCard) + cardGap * index}%)`

Saya juga akan memudahkan penanda anda dengan menggunakan :nth-child() dan bukannya kelas berasingan untuk setiap slaid, hanya sebagai cadangan.

const cards = document.querySelectorAll(".card");
const btnLeft = document.querySelector(".slider__btn--left");
const btnRight = document.querySelector(".slider__btn--right");
let currentCard = 0;
const lastCard = cards.length;
const cardGap = 8;

const goToCard = function(currCard) {
  cards.forEach(
    (card, index) =>
    (card.style.transform = `translateX(${100 * (index - currCard) + cardGap * index}%)`)
  );
};
goToCard(0);

const nextCard = function() {
  if (currentCard === lastCard - 1) currentCard = 0;
  else currentCard++;
  goToCard(currentCard);
};

const previousCard = function() {
  if (currentCard === 0) currentCard = lastCard - 1;
  else currentCard--;
  goToCard(currentCard);
};

btnLeft.addEventListener("click", previousCard);

btnRight.addEventListener("click", nextCard);

.slider {
  display: flex;
  align-items: center;
  justify-content: center;
  position: relative;
}

.card {
  position: absolute;
  top: 6rem;
  height: 10rem;
  width: 10rem;
  display: flex;
  flex-direction: column;
  justify-content: space-between;
  background-color: #634133;
  transition: all 1s;
}

.slider__btn {
  font-size: 3.25rem;
  color: #fff;
  background-color: #634133;
  font-family: sans-serif;
  border: none;
  border-radius: 100%;
  box-shadow: 0 1rem 2rem rgba(0, 0, 0, 0.1);
  position: absolute;
  top: 50%;
  z-index: 10;
  height: 5.5rem;
  width: 5.5rem;
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
  transition: all 0.2 ease;
}

.slider__btn--left {
  left: 15%;
  transform: translate(-50%, 150%);
}

.slider__btn--right {
  right: 15%;
  transform: translate(50%, 140%);
}

.slider__btn:hover {
  background-color: rgba(216, 123, 91, 0.85);
}

.card .photo {
  min-height: 1rem;
  background-color: yellow;
}

.card:nth-child(2) .photo {
  background-color: red;
}

.card:nth-child(3) .photo {
  background-color: purple;
}

.card:nth-child(4) .photo {
  background-color: green;
}

.card:nth-child(5) .photo {
  background-color: blue;
}
