Understanding HTML Attributes

Which of the following best describes what an attribute in an HTML tag does?

A It provides extra information about an element, like its ID or style.

B It creates a new HTML element inside the tag.

C It removes the element from the page.

D It changes the browser's default font.

💡 Hint

Think about how you add details to an HTML tag to change its behavior or appearance.

Attributes add extra details to HTML elements, such as id, class, or href. They do not create or remove elements or change browser defaults directly.
