HTML and CSS Certification Practice Test

The correct method for applying CSS styles inline is through the use of the style attribute. This allows you to add CSS directly to HTML elements by including the style attribute within the opening tag of an element. For example, you can write `<h1 style="color: blue; text-align: center;">Hello World</h1>`, where the color and alignment styles are applied directly to that specific header element.

This approach is useful for quick styling adjustments or when specific styles need to be applied to an individual element without affecting others. It is particularly handy for testing or overriding specific styles temporarily without modifying external stylesheets or internal style tags.
