Custom checkbox

CSS, Visual, Animation

Creates a styled checkbox with animation on state change.

  • Use an <svg> element to create the check <symbol> and insert it via the <use> element to create a reusable SVG icon.
  • Create a .checkbox-container and use flexbox to create the appropriate layout for the checkboxes.
  • Hide the <input> element and use the label associated with it to display a checkbox and the provided text.
  • Use stroke-dashoffset to animate the check symbol on state change and transform: scale(0.9) via a CSS animation to create a zoom animation effect.
