Overflow-y auto makes overflow-x clip invisible


I am trying to create a scroll container for cards where the scroll is performed in the card content only, not in the header or footer. I guess that the container should hide the horizontal overflow and the card should have overflow-y: auto. However, doing so causes that the following cards are not visible.

function MainComponent() {
  const [activeCardIndex, setActiveCardIndex] = React.useState(0);

  const cardsContainerRef = React.useRef(null);
  const cardsRefs = React.useRef([]);

  const updateLayoutOffset = React.useCallback(() => {
    if (!cardsContainerRef.current || !cardsRefs.current[activeCardIndex]) {
      return 0;
    }

    const storyWidth = cardsRefs.current[activeCardIndex].offsetWidth;
    const containerWidth = cardsContainerRef.current.offsetWidth;
    let offset = containerWidth / 2 - storyWidth / 2 - activeCardIndex * storyWidth - activeCardIndex * 8;
    cardsContainerRef.current.style.transform = `translateX(${offset}px)`;
  }, [activeCardIndex]);

  React.useLayoutEffect(() => {
    updateLayoutOffset();
  }, [updateLayoutOffset]);

  React.useEffect(() => {
    updateLayoutOffset();
  }, [activeCardIndex, updateLayoutOffset]);

  const goToNextCard = React.useCallback(() => {
    if (activeCardIndex === cardsRefs.current.length - 1) {
      return;
    }

    setActiveCardIndex(activeCardIndex + 1);
  }, [activeCardIndex]);

  const goToPreviousCard = React.useCallback(() => {
    if (activeCardIndex === 0) {
      return;
    }

    setActiveCardIndex(activeCardIndex - 1);
  }, [activeCardIndex]);

  let cards = ["Card 1", "Card 2", "Card 3"];

  return (
    <div className="flex h-dvh max-h-dvh w-full max-w-full flex-col justify-center overflow-hidden bg-black px-2 py-1 sm:bg-[#1a1a1a] sm:py-3">

            <div ref={cardsContainerRef} className="flex grow flex-row items-center gap-2 overflow-y-auto overflow-x-clip transition-transform duration-500">
              {cards.map((card, index) => (
                <div
                  ref={(el) => {
                    if (el) {
                      cardsRefs.current[index] = el;
                    }
                  }}
                  key={index}

                  {Array(40)
                    .fill(0)
                    .map((_, i) => (

                      </p>
                    ))}
                </div>
              ))}
            </div>
            <div className="flex w-full flex-row items-center p-2">

          </div>
          <button className="rounded-md bg-blue-500 p-2 text-white" onClick={goToNextCard}>
            Next
          </button>
        </div>
      </div>
    </div>
  );
}

ReactDOM.createRoot(document.getElementById("root")).render(<MainComponent />);

I can not find any combination of overflow settings that works fine.


Solution

  • I found a simple solution: setting min-height: 0 in the cards container and overflow: hidden

    function MainComponent() {
      const [activeCardIndex, setActiveCardIndex] = React.useState(0);
    
      const cardsContainerRef = React.useRef(null);
      const cardsRefs = React.useRef([]);
    
      const updateLayoutOffset = React.useCallback(() => {
        if (!cardsContainerRef.current || !cardsRefs.current[activeCardIndex]) {
          return 0;
        }
    
        const storyWidth = cardsRefs.current[activeCardIndex].offsetWidth;
        const containerWidth = cardsContainerRef.current.offsetWidth;
        let offset = containerWidth / 2 - storyWidth / 2 - activeCardIndex * storyWidth - activeCardIndex * 8;
        cardsContainerRef.current.style.transform = `translateX(${offset}px)`;
      }, [activeCardIndex]);
    
      React.useLayoutEffect(() => {
        updateLayoutOffset();
      }, [updateLayoutOffset]);
    
      React.useEffect(() => {
        updateLayoutOffset();
      }, [activeCardIndex, updateLayoutOffset]);
    
      const goToNextCard = React.useCallback(() => {
        if (activeCardIndex === cardsRefs.current.length - 1) {
          return;
        }
    
        setActiveCardIndex(activeCardIndex + 1);
      }, [activeCardIndex]);
    
      const goToPreviousCard = React.useCallback(() => {
        if (activeCardIndex === 0) {
          return;
        }
    
        setActiveCardIndex(activeCardIndex - 1);
      }, [activeCardIndex]);
    
      let cards = ["Card 1", "Card 2", "Card 3"];
    
      return (
