NEW QUESTION # 45
Which three methods are associated with the HTML5 localStorage API? Choose 3.
Answer: A,B,E
Explanation:
The correct methods are setItem(), removeItem(), and clear(). The HTML5 Web Storage API exposes localStorage as a persistent key-value storage object for the current origin. Data stored in localStorage remains available after page reloads and browser restarts unless it is explicitly removed or cleared. setItem (key, value) stores a value under a named key or updates the value if the key already exists. removeItem(key) deletes one specific key-value pair from storage. clear() removes all key-value pairs from the storage object for that origin. These methods are part of the standard Storage interface used by both localStorage and sessionStorage. write is not a Web Storage method; it is associated with document-writing behavior, not application state storage. cookie is also incorrect because cookies are a separate browser storage mechanism accessed through document.cookie, not a method of localStorage.

NEW QUESTION # 46
Which two background graphics will automatically adjust to different screen sizes? Choose 2.
Note: You will receive partial credit for each correct selection.
Answer: C,D
Explanation:
The correct answers are A and C because background-size: contain and background-size: cover are the CSS values that scale a background image in response to the size of the element or viewport. contain scales the background image as large as possible while preserving the entire image inside the background area. This prevents cropping and maintains the image's aspect ratio, although empty space may appear if the container and image proportions differ. cover also preserves the aspect ratio, but scales the image until the entire background area is filled; this may crop part of the image, but it prevents empty space. Both values are commonly used in responsive design because the image automatically recalculates its rendered size as the page or element changes dimensions. initial resets the property to its default behavior and does not intentionally create responsive scaling. auto uses the image's intrinsic dimensions or proportional automatic sizing, so it does not reliably adjust the graphic to different screen sizes in the way required.

NEW QUESTION # 47
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.
Answer:
Explanation:
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.
NEW QUESTION # 48
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);
Answer: B
Explanation:
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.
NEW QUESTION # 49
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?
Answer: A
Explanation:
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.
