Question 51

Which 3D transform affects the distance between the z-plane and the user?

A.
B.
C.
D.

Correct Answer: A

The perspective(n) method in CSS is used to affect the distance between the z-plane and the user, effectively changing the perspective depth of a 3D transformed element.
* perspective(n) Method: The perspective function defines how far the element is from the user. It affects the appearance of the 3D transformed element, giving it a sense of depth.
* Usage Example:
container {
perspective: 1000px;
}
In this example, the perspective is set to 1000 pixels, which defines the distance between the z-plane and the user.
* Properties:
* n: This represents the perspective distance. The lower the value, the more pronounced the perspective effect.

* MDN Web Docs on perspective
* W3C CSS Transforms Module Level 1

Question 54

A developer needs to apply a red font color to the navigation, footer, and the first two of three paragraphs on a website.
The developer writes the following code:

Which CSS archives this developer's goal?

A.Content
B.Padding
C.Margin
D.border

Correct Answer: A

To apply a red font color to the navigation, footer, and the first two of three paragraphs on a website, the correct CSS would use the content attribute to achieve the desired styling. However, the term "content" isn't correct in the given context. The appropriate answer involves directly specifying styles for these elements using CSS selectors.
Here's the correct CSS:
nav, footer, p.standard:nth-of-type(1), p.standard:nth-of-type(2) {
color: red;
}
Explanation:
* CSS Selectors: The selectors nav, footer, p.standard:nth-of-type(1), and p.standard:nth-of-type(2) are used to target the specific elements. The nth-of-type pseudo-class is used to select the first and second paragraphs.
* Applying Styles: The color: red; style rule sets the text color to red for the specified elements.

* MDN Web Docs on CSS Selectors
* W3C CSS Specification on Selectors

Question 55

What allows a scripting language to manipulate elements on a web page?

A.CSS
B.XML
C.HTML
D.DOM

Correct Answer: D

The Document Object Model (DOM) is an API for HTML and XML documents that defines the logical structure of documents and the way a document is accessed and manipulated.
* DOM Explanation:
* The DOM represents the page so that programs can change the document structure, style, and content.
* It provides a way for scripts to update the content, structure, and style of a document while it is being viewed.
* Explanation:
* Option A: CSS is incorrect because it is used for styling web pages.
* Option B: XML is incorrect because it is a markup language, not an API for manipulating web page elements.
* Option C: HTML is incorrect because it is the markup language used to create web pages, not an API for manipulation.
* Option D: DOM is correct because it allows a scripting language to manipulate elements on a web page.
:
MDN Web Docs - DOM
W3Schools - JavaScript HTML DOM
