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.

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