Using JavaScript
The HTML element can also be styled using JavaScript and the element’s id.

<script>
function my_function() {
document.getElementById('my_div').style.counterIncrement = 'new_counter_section';
}
</script>CSS Notes:
- The “inherit”, “initial” and “unset” keywords can be used with any CSS property to set its value
- In CSS there are many ways to express a color value in a property
