Here we use the size property to return the total entries within the button elements computedStyleMap
.
js
// grab our element const buttonEl = document.querySelector("button"); // we can retrieve all computed styles with `computedStyleMap` const allComputedStyles = buttonEl.computedStyleMap(); // use size to get the total styles within the map const amountStyles = allComputedStyles.size; console.log(amountStyles); // logs 338
