Shifting Card

CSS, Animation · Dec 14, 2022

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.
