質問 # 62
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?
正解：D
解説：
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).

Review the following markup segment:
< form action= " process.js " method= " get " >
< label for= " secretcode " > Secret Code < /label >
< input type= " text " name= " secretcode "
pattern= " [a-zA-Z]{4}-[0-9] {2}-[0-9]{4}-[a-zA-Z] {4} "
placeholder= " secretcode " >
< input type= " submit " value= " Submit " >
< /form >
Which entry will validate successfully according to the required pattern?
正解：A
解説：
The correct answer is D because the pattern attribute requires the exact structure defined by the regular expression [a-zA-Z]{4}-[0-9] {2}-[0-9]{4}-[a-zA-Z] {4}. The first group, [a-zA-Z]{4}, requires exactly four alphabetic characters. The second group, [0-9] {2}, requires exactly two numeric digits. The third group, [0-9]
{4}, requires exactly four numeric digits. The final group, [a-zA-Z] {4}, requires exactly four alphabetic characters. Hyphens must appear between each group. Option D, kukX-34-4938-WJDF, satisfies every part:
kukX is four letters, 34 is two digits, 4938 is four digits, and WJDF is four letters. Option A fails because Uhj6 contains a digit in the final letter-only group. Option B fails because y7Ts contains a digit in the first group and A3 is not two digits. Option C fails because 23h contains a letter and breaks the two-digit group.

質問 # 64
The ctx variable is the context of an HTML5 canvas object. What does the following HTML markup draw?
ctx.arc(x, y, r, 0, Math.PI, true);
正解：B
解説：
The statement draws a semicircle at the specified point. The arc() method of the Canvas 2D API adds a circular arc to the current path. Its core parameters are the center point x, y, the radius, the starting angle, the ending angle, and an optional direction flag. In this expression, x and y define the center of the arc, and r defines its radius. The start angle is 0 radians, and the end angle is Math.PI radians. Since Math.PI represents
180 degrees, the path covers exactly half of a full circle. The final argument, true, tells the canvas context to draw the arc counterclockwise rather than using the default clockwise direction; however, the angular span remains half of the circumference. The call does not draw a complete visible shape unless the path is later stroked or filled, but the geometric path being created is a semicircular arc. It is not a straight line, square, or full circle. References/topics: Canvas 2D context, arc() method, radians, path construction, drawing arcs and circles.
質問 # 65
Match each property to its corresponding value for creating the CSS flexible box layout.
Move each property from the list on the left to the correct value on the right.
Note: You will receive partial credit for each correct match.
正解：
解説：
Explanation:
A CSS flexible box layout is created by applying the display property to a container with either flex or inline- flex. This establishes the element as a flex container and causes its child elements to become flex items. The flex-direction property defines the direction of the main axis and accepts row, row-reverse, column, and column-reverse, allowing items to flow horizontally, vertically, or in reverse order. The align-items property controls how flex items are aligned along the cross axis, with values such as flex-start, flex-end, and center.
The direction property controls writing direction and accepts ltr for left-to-right text flow or rtl for right-to-left text flow. Finally, order is applied to individual flex items and accepts an integer value, represented here as
"any," because any numeric order value can be used to rearrange item display order without changing the document source order. References/topics: CSS flexbox, flex containers, flex items, main axis, cross-axis alignment, writing direction, item ordering.

The following two images show a web page that uses a responsive layout displayed on a mobile device and on a PC.
Displayed on a mobile device:
The layout stacks the content vertically.
Displayed on a computer monitor:
The layout displays the content cards horizontally in multiple columns.
Review the images on the left.
Complete the statements by selecting the correct option from each drop-down list.
正解：
解説：
Explanation:
First drop-down: flex boxes
Second drop-down: background-size
Third drop-down: cover
The layout changes from a stacked mobile layout to a multi-column desktop layout without relying on media queries. That behavior is commonly achieved with responsive flex boxes, where items can wrap naturally based on the available width. The header image must fill the available header area on both mobile and desktop. For that requirement, the correct CSS property is background-size, and the correct value is cover.
background-size: cover scales the image so the entire header area is filled, even if part of the image is cropped. contain would preserve the full image but could leave empty space, and auto would keep the image at its natural size.
