NEW QUESTION # 44
The following output has more text than will fit in the element.
You need to apply CSS to contain the text inside the element ' s border without creating unneeded scrollbars or losing text. Which attribute setting should you use?
Answer: C
Explanation:
The correct setting is overflow: auto;. The CSS overflow property controls how content behaves when it does not fit inside an element's padding box. The requirement has three parts: keep the text inside the element's border, avoid unnecessary scrollbars, and avoid losing text. overflow: hidden clips overflowing content and does not provide a user-visible scrollbar, so text can become inaccessible. overflow: visible allows excess content to render outside the element's box, failing the containment requirement. overflow: scroll makes the element scrollable, but user agents display scrollbars whether or not content is actually overflowing, which violates the requirement to avoid unneeded scrollbars. MDN describes overflow: auto as clipping overflow content at the padding box while allowing it to be scrolled into view, with scrollbars displayed only when content is actually overflowing. This makes auto the precise choice for a controlled text container. References

NEW QUESTION # 45
You need to complete a postal code input form element (post_code). Include attributes to make the field mandatory, set the data type as text, and limit the input to five numeric digits.
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 blank: type
Second blank: pattern
Third blank: required
The first blank must be type because the question requires the input data type to be text, producing type= " text " . The second blank must be pattern because [0-9]{5} is a regular expression that permits exactly five numeric digits. The third blank must be required because the postal code field must be mandatory before the form can be submitted.
NEW QUESTION # 46
Which two statements correctly describe media queries? Choose 2.
Answer: B,C
Explanation:
Media queries support responsive web design and allow different CSS rules to be applied at different screen sizes, device characteristics, or breakpoints. MDN describes media queries as a CSS mechanism for applying styles depending on media type and device or viewport characteristics, including width, height, resolution, and orientation. This is the foundation of responsive design because a page can adapt its layout for phones, tablets, laptops, and desktop displays without changing the HTML document. Breakpoints are the points where the design changes; MDN identifies them as the points where a media query is introduced to improve layout behavior across viewport sizes. Statement A is not generally correct because media queries are primarily a styling and layout mechanism, not a direct performance optimization. They can sometimes help avoid unsuitable layouts, but performance improvement is not their defining purpose. Statement D is incorrect because media queries are CSS rules; they do not execute or dynamically process JavaScript code. References
/topics: responsive design, CSS media queries, viewport width, breakpoints, adaptive layout rules.
NEW QUESTION # 47
Which three events are valid for the HTML canvas element? Choose 3.
Answer: B,C,E
Explanation:
The valid selections are mouseup, scroll, and blur. A < canvas > element is represented by HTMLCanvasElement, which inherits from HTMLElement; therefore, it participates in the normal DOM event model for element-based interaction. mouseup is valid because it is fired on an Element when a pointing-device button is released while the pointer is over that element, which is a common canvas interaction pattern for drawing tools, games, drag tracking, and selection behavior. scroll is valid as an element event when an element is scrolled, and the HTML event-handler index lists onscroll for HTML elements. blur is also valid because it fires when an element loses focus; a canvas can participate in focus workflows, particularly when made focusable with attributes such as tabindex. play is excluded in this certification context because it is a media playback event associated with HTMLMediaElement behavior, not canvas graphics interaction. datareceived is not a standard HTML canvas or DOM event. References/topics:
canvas DOM interaction, element event listeners, mouse events, focus events, scroll events.
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: A
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.
