QUESTION: 19

Which layout method causes images to render to small or too large in browser windows of different sizes?

Fluid
Fixed width
Liquid
Relative width

Answer(s): B

Explanation:

A fixed-width layout method specifies exact pixel values for widths. This approach does not adapt to different screen sizes, leading to images rendering too small or too large on various devices.

Fixed Width Layout:

Definition: Uses specific pixel values for the width of elements.

Example:

.container {

width: 800px;

}

Issues:

Lack of Flexibility: Does not scale with the size of the viewport, causing images and other elements to appear incorrectly sized on different screen sizes.

Comparison:

Fluid/Liquid: Adapts to the screen size using percentages or other relative units.

Relative Width: Also adapts using units like em or %.

QUESTION: 20

Which CSS transformation method should a developer use to reposition an element horizontally on the 2-D plane?

Skewx (angle)
Scale (x,y)
Translatex(n)
Scalex(n)

Answer(s): C

Explanation:

The translateX(n) method in CSS is used to move an element horizontally on the 2-D plane by a specified distance. This transformation repositions the element along the X-axis.

translateX(n) Method: The translateX(n) function moves an element horizontally by n units. Positive values move the element to the right, while negative values move it to the left.

Usage Example:

.element {

transform: translateX(100px);

}

In this example, the element is moved 100 pixels to the right.

Properties:

n: This represents the distance to move the element. It can be specified in various units such as pixels (px), percentages (%), ems (em), etc.

B)

C)

D)

Option A
Option B
Option C
Option D

Answer(s): A

Explanation:

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.
