Creates a toggle switch with CSS only.

• Use the for attribute to associate the <label> with the checkbox <input> element.
• Use the :after pseudo-element of the <label> to create a circular knob for the switch.
• Use the :checked pseudo-class selector to change the position of the knob, using transform: translateX(20px) and the background-color of the switch.
• Use position: absolute and left: -9999px to visually hide the <input> element.

<input type="checkbox" id="toggle" class="offscreen" />
<label for="toggle" class="switch"></label>
