# Animated Fill and Strikethrough Checkboxes

A Pen created on CodePen.io. Original URL: [https://codepen.io/jkantner/pen/QWKydLJ](https://codepen.io/jkantner/pen/QWKydLJ).

A checkbox concept where the unchecked state is secretly a square covering the checkmark. When checked, the fill is shaped into a line and penetrates the label text. The reverse happens when unchecked again.
