Answer Key
HTML & CSS · Modules 11–20 · Student wording will vary for definitions
1<hr> — A self-closing HTML element that draws a horizontal line across the page, used to create a visual and thematic break between sections.
2<strong> — An inline HTML element that marks text as important. Browsers display it bold. Use it when the content has semantic importance, not just for visual styling.
3attribute — Extra information added to an HTML opening tag as a name="value" pair, such as class="header" or href="page.html".
4id — An HTML attribute that gives an element a unique identifier on the page. No two elements may share the same id value.
5class — An HTML attribute that assigns CSS class names to an element. The same class can be reused on many elements for shared styling.
6href — An attribute on the <a> element that specifies the URL destination of the hyperlink. Without href, the link has no destination to navigate to.
7alt — An attribute on <img> that provides a text description of the image, shown when the image fails to load and read aloud by screen readers for accessibility.
8<ul> — An HTML element that creates an unordered (bulleted) list. Each item inside must be wrapped in an <li> element.
9<ol> — An HTML element that creates an ordered (numbered) list. Each item must be wrapped in an <li> and the browser numbers them automatically.
10<div> — A generic block-level container element with no built-in styling. Used to group content so CSS can target and style sections of a page.
