Q
How can you dynamically change the CSS style of an HTML element using JavaScript?

Answer & Solution

Answer: Option A
Solution:
To dynamically change the CSS style of an HTML element using JavaScript, you can use the style property of the element to directly modify CSS styles. For example, element.style.backgroundColor = 'red'; sets the background color of the element to red dynamically. This approach allows for inline style modifications directly from JavaScript.
