質問 # 67
Review the grid container requirements and mockup on the left. Which markup should you use to define the grid container?
正解：C
解説：
The correct segment is D because named grid-region layouts are defined with grid-template-areas. This CSS Grid property specifies named grid areas, establishes the cells in the grid, and assigns names to those cells.
The syntax requires each row of the grid template to be written as a quoted string, with repeated names indicating that the named area spans multiple columns or rows. In the shown layout, heading spans the entire top row, menu occupies the left column across lower rows, content spans the central area, right occupies the right-side area, and contact spans the bottom content region. Options B and C are incorrect because named grid-area strings do not belong in grid-template-rows or grid-template-columns; those properties define track sizing, not named layout regions. Option A defines explicit column and row sizes but does not define the semantic named areas shown in the mockup. References/topics: CSS Grid, grid containers, named grid areas, grid-template-areas, responsive page layout.

You want to display a message box showing the user ' s current latitude and longitude as identified by the user' s browser.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
正解：
解説：
Explanation:
First drop-down: navigator.geolocation
Second drop-down: navigator.geolocation
Third drop-down: getCurrentPosition(showLocation)
The correct API object is navigator.geolocation because browser-based geographic location is exposed through the Geolocation API, not through window.location. window.location represents the current page URL and navigation state; it does not provide latitude or longitude. The first selection checks whether the browser supports geolocation by evaluating navigator.geolocation. Inside the block, the same object must be used to request the user's current position. The correct method is getCurrentPosition(showLocation), which requests the device's current location and passes a position object to the callback function when the location is available. The callback then reads position.coords.latitude and position.coords.longitude and displays those values with alert(). The alternatives that pass window.location are incorrect because they provide page- location information rather than geographic coordinates. The alternatives that call showLocation(...) directly are also incorrect because the browser must first retrieve the actual position object. References/topics:
Geolocation API, navigator.geolocation, getCurrentPosition(), callback functions, latitude and longitude.
質問 # 69
You write the following JavaScript code. Line numbers are included for reference only.
01 < script >
02
03 beststudent = new Student( " David " , " Hamilton " );
04 document.write(beststudent.fullname + " is registered. " );
05 < /script >
You need to write a function that will initialize and encapsulate the member variable fullname.
Which code fragment could you insert at line 02 to achieve this goal?
Note: Each correct answer presents a complete solution.
正解：B
解説：
The correct answer is A because the code at line 03 creates an object by calling a constructor function with the new keyword. A constructor function must be declared with the same identifier used in the new Student( " David " , " Hamilton " ) expression. Inside the constructor, instance members should be assigned through this, because this refers to the newly created object. Option A correctly initializes this.firstname, this.lastname, and this.fullname, so beststudent.fullname is available at line 04 and evaluates to " David Hamilton " . Option B is invalid JavaScript syntax because var student(firstName, lastName) is not a valid function declaration. Option C is also invalid syntax for the same reason: var Student(firstname, lastname) cannot declare a constructor.
Option D uses a valid function declaration, but it assigns firstname, lastname, and fullname without this, which creates or references non-encapsulated variables rather than properties of the constructed object.
References/topics: JavaScript constructor functions, new keyword, object instance properties, this, custom classes.
質問 # 70
You want to position a specific element so that it always directly follows the previous element, which is positioned by default, regardless of the viewport characteristics. Which positioning method should you use?
正解：B
解説：
The correct positioning method is static. In CSS, position: static is the default positioning behavior for elements. A statically positioned element remains in the normal document flow, meaning it is laid out according to the order of the markup and directly follows preceding elements unless another layout rule changes that flow. MDN defines static positioning as placing the element according to the normal flow of the document, with top, right, bottom, left, and z-index having no effect. This matches the requirement that the element always directly follows the previous default-positioned element and does not depend on viewport characteristics. absolute removes the element from normal flow and positions it relative to a containing block.
fixed also removes it from normal flow and positions it relative to the viewport. sticky starts in normal flow but changes behavior relative to a scrolling ancestor when a threshold is crossed. References/topics: CSS positioning, normal document flow, static positioning, viewport-independent layout.
質問 # 71
Which two functions support 2D transformations in CSS3? Choose 2.
正解：B、D
解説：
The correct transformation functions are matrix() and skew(). CSS transformations are applied with the transform property and accept transform functions that alter an element's rendered appearance in two- dimensional or three-dimensional space. MDN defines < transform-function > as a data type representing a transformation that can rotate, resize, distort, or move an element in 2D or 3D space. The matrix() function is valid because it defines a homogeneous two-dimensional transformation matrix, allowing translation, scaling, rotation, and skewing effects to be represented numerically in one function. The skew() function is also valid because it explicitly skews an element on the 2D plane. scroll() is not a CSS transform function; scrolling is handled through overflow behavior or scrolling APIs. move() is also not a valid CSS transform function; the standard transform function for movement is translate(). References/topics: CSS3 transforms, transform property, 2D transformation functions, matrix(), skew().
