The <IFRAME> element displays content from another page within the current document. It creates an inline frame that embeds external HTML documents, videos, or other web content. IFrames are commonly used for embedding maps, social media widgets, or advertisements within pages.

HTML (Hypertext Markup Language) provides structure for web pages by defining how content is organized and displayed. It uses tags to mark up text, images, links, and other elements that browsers interpret and render. HTML is the foundation of web development, creating the skeleton upon which CSS styles and JavaScript functionality are built.

HTML comments use the format with comment text enclosed in angle brackets with exclamation and dashes. Comments are ignored by browsers and useful for documentation or temporarily disabling code. They do not display on the rendered page but are visible in source code.

The dl tag defines definition lists (term-description pairs like glossaries), and li is NOT a valid list item. Definition lists use dt (definition term) and dd (definition description) instead of li. This specialized list structure pairs terms with their explanations, perfect for dictionaries, FAQs, or metadata displays.

This technique allows complex navigation through a single image with different hotspots for different actions.

Use the kbd element to mark keyboard entry text semantically. It indicates text users should type.

The <EM> element is used for emphasized text that carries stress emphasis in the content. Browsers typically display it in italics, but its primary purpose is semantic meaning rather than styling. Screen readers may pronounce emphasized text differently, making it important for accessibility.

TRUE because while HTML allows some unclosed tags, closing all tags is good practice for consistency and compatibility with XML-based technologies like XHTML. Proper tag closure prevents errors when working across different markup languages and improves code maintainability and readability.

Scripts are typically included in the body section for page functionality. They can also appear in head for early loading.

The correct file extension for an HTML file is .html (or .htm for compatibility with older systems). This extension tells the browser to interpret the file as HTML code. Both .html and .htm work identically, though .html is the modern standard and more commonly used.

The <ol> tag creates an ordered (numbered) list where items are automatically numbered sequentially. By default, numbering starts at 1 and increments for each list item. The numbering style can be customized to use letters, Roman numerals, or other formats using CSS or HTML attributes.

An absolute URL is a complete web address that includes the protocol (http:// or https://), domain name, and full path to a resource.

An <iframe> is used to embed another document within the current HTML document.

IFrames maintain separate document contexts, allowing independent content to coexist within a single page.

Alternative text should briefly represent image purpose for accessibility. The alt attribute provides this description.

DML Data Manipulation Language is not a markup language because it is a database query language for manipulating data. Markup languages include XHTML, XML, and GML which use tags to structure documents. DML belongs to SQL for database operations not document markup.

The onload event attribute does not require a mouse click to trigger - it fires automatically when an element finishes loading.
