CSS Properties in JavaScript: Setting Background Color

Question: How can we modify an HTML element's background color dynamically using JavaScript?

Answer: JavaScript leverages camelCase notation for accessing CSS properties, omitting dashes. Therefore, "background-color" translates to "backgroundColor."

To illustrate:

<code class="javascript">function setColor(element, color) {
    element.style.backgroundColor = color;
}

// where el is the specific element
var el = document.getElementById('elementId');
setColor(el, 'green');</code>

This code snippet demonstrates setting the background color of an element with ID "elementId" to green.
