HTML and CSS Certification Practice Test

The tag used to define an internal style sheet in HTML is the style tag. When you use the style tag, it allows you to write CSS directly within the HTML document, typically placed in the head section. This approach is useful for applying styles specific to that particular webpage without affecting others.

By placing CSS rules within the style tag, you can directly manipulate the presentation of elements on that page, ensuring that styles are easily maintainable and localized. This is especially beneficial for small projects or single-purpose HTML documents where external stylesheets may not be necessary.

Using other tags like script or link would not yield the same result. The script tag is meant for embedding JavaScript, while the link tag is typically used to link to external style sheets rather than defining styles internally. The css tag does not exist in HTML, which makes the style tag the correct choice for defining internal styles.
