The DOM is a standard that enables you to manipulate HTML elements and attributes in a Web document. What do you use to work with the DOM?

• A. A markup language such as HTML.
• B. A style sheet language such as CSS.
• C. A database query language such as SQL.
• D. A scripting language such as JavaScript.

Answer: (D)

Working with the DOM requires a scripting language that can access its API. The DOM is a programmatic interface for HTML elements and attributes, so to change them at runtime you write code in a scripting language such as JavaScript. HTML defines the structure of the page, CSS handles styling, SQL interacts with databases, but only JavaScript lets you read, modify, or create elements, attributes, and the document tree, and respond to user actions. For example, you can use document.getElementById('title').textContent = 'Hello'; or document.querySelector('.item').classList.add('active'); to dynamically alter the page.
