Question#1

Which attribute should a developer add to an HTML element to enable the HTML5 drag-and-drop application programming interface (API)?

A. draggable
B. ondragover
C. ondragstart
D. dragstart

Explanation:
> “The `draggable` attribute is a global attribute in HTML5 that indicates whether an element is draggable. When set to `true`, the element becomes draggable using the drag-and-drop API.”
Example:
```html
<div draggable="true">Drag me</div>
```
* `ondragover` and `ondragstart` are event handlers, not attributes enabling drag.
* `dragstart` is an event, not an attribute.
Reference:
* MDN Web Docs: draggable attribute
* HTML Drag and Drop API Specification

Question#2

Which step helps ensure that code passes validation?

A. Adopting a single standard
B. Adopting multiple standards
C. Avoiding references prior to HTML version 4.01
D. Avoiding references prior to HTML version 5

Explanation:
Validation checks whether a web page is written according to the rules defined by a particular standard (such as HTML5 or CSS3). To pass validation consistently, it's essential to adhere to one standard throughout the page or project.
"Adopting a single markup standard ensures uniform structure and syntax, reducing errors and inconsistencies that prevent validation success."
"Mixing different standards can lead to validation errors and unpredictable behavior in web browsers."
Reference: W3C Markup Validation Service Documentation
HTML5 Coding Standards C W3C

Question#3

Which property should a developer use to ensure that a background image appears only once?

A. background-origin
B. background-size
C. background-clip
D. background-repeat

Explanation:
> “The `background-repeat` property in CSS defines how background images are repeated. To prevent a background image from repeating, use `background-repeat: no-repeat;`.”
>
> “The default value is `repeat`, which tiles the image both horizontally and vertically unless
otherwise specified.”
Reference:
* MDN Web Docs: background-repeat
* CSS Backgrounds and Borders Module

Question#4

Which structure tag should a developer use for blogs, images, and social media posts?

A. <article>
B. <main>
C. <aside>
D. <section>

Explanation:
The <article> element represents a self-contained composition in a document that is intended to be independently distributable or reusable. It is ideal for blog entries, news stories, forum posts, and similar content.
"The <article> element is used for content that forms an independent part of a document or site such as blog entries, news items, or user comments."
"It is suitable for self-contained content that could stand on its own if distributed separately."
Reference: HTML5 Specification (Sectioning Content) C W3C
HTML Reference Guides C MDN

Question#5

Which option changes the content of the first line to a valid CSS comment?

A. /* this is a comment */
B. <! "this is a comment">
C. <!-- this is a comment -->
D. // this is a comment

Explanation:
In CSS, comments must begin with /* and end with */.
“CSS comments are placed inside /* and */. These comments can span multiple lines and are ignored by the browser.”
HTML-style comments using <!-- --> and JavaScript-style comments using // are not valid in CSS and may cause parsing errors.
Reference: CSS Syntax Specification
MDN Web Docs C CSS Comments
W3Schools C CSS Comment Rules
