Custom radio button

Angelos Chalaris · CSS, Visual, Animation · Nov 16, 2022

Creates a styled radio button with animation on state change.

  • Create a .radio-container and use flexbox to create the appropriate layout for the radio buttons.
  • Reset the styles on the <input> and use it to create the outline and background of the radio button.
  • Use the ::before element to create the inner circle of the radio button.
  • Use transform: scale(1) and a CSS transition to create an animation effect on state change.
