30秒学会 CSS 片段 – Shifting Card

Creates a card that shifts on hover.

• Set the appropriate perspective on the .container element to allow for the shifting effect.
• Add a transition for the transform property of the .card element.
• Use Document.querySelector() to select the .card element and add event listeners for the mousemove and mouseout events.
• Use Element.getBoundingClientRect() to get the x, y, width, and height of the .card element.
• Calculate the relative distance as a value between -1 and 1 for the x and y axes and apply it through the transform property.

const cx = x + width / 2;
const cy = y + height / 2;

const handleMove = e => {
  const { pageX, pageY } = e;
  const dx = (cx - pageX) / (width / 2);
  const dy = (cy - pageY) / (height / 2);
  e.target.style.transform =
    `rotateX(${10 * dy * -1}deg) rotateY(${10 * dx}deg)`;
};

const handleOut = e => {
  e.target.style.transform = 'initial';
};

card.addEventListener('mousemove', handleMove);
card.addEventListener('mouseout', handleOut);
