IT Specialist HTML5 Application Development Sample Questions (Q64-Q69):

NEW QUESTION # 64
Which markup segment uses the output element to display the combined value of two input elements in HTML5?

A. < form > < input type= " number " name= " a " value= " 50 " / > + < input type= " number " name= " b
" value= " 50 " / > = < output name= " c " for= " a b " > < /output > < /form >
B. < form oninput= " a.value+b.value " > < input type= " number " name= " a " value= " 50 " / > + < input type= " number " name= " b " value= " 50 " / > < /form >
C. < form > < input type= " number " name= " a " value= " 50 " / > + < input type= " number " name= " b
" value= " 50 " / > = < output name= " c " for= " a b " > a+b < /output > < /form >
D. < form oninput= " c.value=a.value+b.value " > < input type= " number " name= " a " value= " 50 " / >
+ < input type= " number " name= " b " value= " 50 " / > = < output name= " c " for= " a b " > < /output
> < /form >

Answer: D

Explanation:
Option C is the only segment that correctly combines three required pieces: two contributing < input > controls, a named < output > control, and executable form-level logic that assigns a calculated value into that output. The HTML < output > element is specifically designed as a container for the result of a calculation or user action, and its for attribute identifies the controls that contributed to the calculation by using a space- separated list of element identifiers or associated names in the form workflow. MDN's reference demonstrates this exact pattern: two input values are added, and the result is assigned to an < output > element whenever input changes. Option A renders literal text inside < output > but does not update it. Option B has no < output
> element at all, so it cannot satisfy the requirement. Option D declares an output but lacks an oninput handler or script assignment, so the displayed value never changes. References/topics: HTML5 forms, < output > element, for attribute, form input events, calculated form results.

NEW QUESTION # 65
You need to correctly apply a style rule for screen devices with a width of 480 pixels or less.
Complete the code by selecting the correct option from the drop-down list.

Answer:

Explanation:

Explanation:
@media screen and (max-width: 480px) {
/* style rules go here */
}
The correct media query is @media screen and (max-width: 480px) {. The requirement says the style rule must apply to screen devices with a width of 480 pixels or less. In CSS media queries, screen identifies the media type, and (max-width: 480px) defines the upper viewport-width limit. This means the enclosed CSS rules apply when the viewport is 480 pixels wide or any smaller value, which is the standard mobile breakpoint behavior. @media screen and (width: 480px) is incorrect because it applies only when the viewport is exactly 480 pixels wide, not below it. @media screen display and (width: 480px) is invalid syntax because display is not used that way in a media query. @media screen-width: 480px is also invalid because it does not follow the required @media media-type and (feature: value) pattern. References/topics: responsive design, CSS media queries, @media, screen media type, max-width, mobile breakpoint styling.

NEW QUESTION # 66
You are drawing on the canvas defined by the white square.

At which x, y coordinate is the upper-left corner of the filled square?

A. 50,0
B. 0,0
C. 0,50
D. 50,50

Answer: D

Explanation:
The correct coordinate is 50,50. In an HTML5 canvas, the coordinate system begins at the upper-left corner of the canvas. The x-coordinate increases as you move to the right, and the y-coordinate increases as you move downward. Therefore, 0,0 represents the top-left corner of the entire white canvas area. In the displayed image, the filled black square is not positioned at the top-left edge, top-center, or left-center of the canvas.
Instead, its upper-left corner is offset both horizontally and vertically from the origin. Among the available choices, 50,50 is the only coordinate that moves the square 50 units to the right and 50 units down from the canvas origin. This matches the visual placement of the filled square inside the white canvas. Option A would place the square at the canvas origin. Option B would place it along the left side, halfway down. Option C would place it along the top edge, halfway across. References/topics: HTML5 canvas coordinate system, x/y positioning, drawing rectangles, fillRect(x, y, width, height).

NEW QUESTION # 67
Which two CSS segments are valid filter properties? Choose 2.

A. filter: blur(25deg)
B. filter: opacity(25%)
C. filter: box-shadow(16px 24px 24px green)
D. filter: drop-shadow(16px 16px 16px red)

Answer: B,D

Explanation:
The valid filter declarations are filter: opacity(25%) and filter: drop-shadow(16px 16px 16px red). The CSS filter property applies graphical effects to an element, commonly including image rendering effects such as blur, contrast, color shifts, transparency, and shadows. opacity(25%) is a valid filter function because filter opacity accepts a percentage or number to control the rendered transparency of the element. drop-shadow (16px 16px 16px red) is also valid because drop-shadow() is a CSS filter function, and MDN shows that it accepts two or three length values plus an optional color. box-shadow(...) is invalid in this context because box-shadow is a standalone CSS property, not a filter function; MDN explicitly distinguishes drop-shadow() from the box-shadow property. blur(25deg) is invalid because blur uses a length value such as pixels, not an angular value such as degrees. References/topics: CSS filter property, image effects, opacity filter, drop- shadow filter, valid filter-function syntax.
