                                IT Specialist HTML5 Application Development Sample Questions (Q22-Q27):

                                NEW QUESTION # 22
                                You need to display the following user interface:
                                A text input field that displays a selectable suggestion list containing:
                                Motorcycle
                                Truck
                                Boat
                                Car
                                Bicycle

                                Answer:

                                Explanation:

                                Explanation:

                                The correct markup uses the HTML5 < datalist > element because the interface shows a text input with a drop- down list of suggested values. The < input > element has list= " vehicles " , which means it must be connected to a < datalist > whose id value is exactly vehicles. This relationship is essential: the list attribute on the input references the id of the datalist that supplies the available options. Each < option > element inside the datalist defines one suggested value: Motorcycle, Truck, Boat, Car, and Bicycle. Unlike a traditional < select > element, a datalist does not restrict the user only to the listed choices; the user can either select an option with the mouse or type directly into the input field. That behavior matches the displayed interface, where the control appears as an editable text box with suggestions. The final closing tag must be < /datalist > because the option elements belong to the datalist container. References/topics: HTML5 forms, < input list > , < datalist > , option elements, selectable typed input.


                                NEW QUESTION # 23
                                You have created custom error messages for a form. When a user attempts to submit the form with invalid data, the following must occur:
                                * The data must remain in the form.
                                * Error messages must be displayed.
                                Which Event property or method should you use?

                                Answer: A

                                Explanation:
                                The correct method is preventDefault(). In an HTML form submission workflow, the browser's default action is to submit the form, which commonly navigates away from the current page or reloads it. Calling event.
                                preventDefault() inside the form's submit event handler cancels that default action, allowing the current form state to remain visible while custom validation logic displays error messages. MDN defines preventDefault() as the method that cancels the default action normally taken by the implementation for that event. The submit event is the correct event context because it fires when the form submission is triggered. defaultPrevented is only a Boolean property indicating whether cancellation has already occurred; it does not cancel anything.
                                cancelable only reports whether an event can be canceled. abort is not the correct form-validation event method. References/topics: HTML5 form validation, custom validation messages, submit event handling, event cancellation, preserving user input.


                                NEW QUESTION # 24
                                The logo shown is displayed on a web page as an SVG.
                                Note: The coordinate values are labeled for reference.
                                Evaluate the image on the left and complete the markup by selecting the correct option from each drop-down list.
                                Note: You will receive partial credit for each correct selection.

                                Answer:

                                Explanation:

                                Explanation:

                                The SVG image is built from three filled polygon faces, one white ellipse, and two white diagonal line segments. The three < polygon > elements define the black cube faces by connecting multiple coordinate points. The small white oval on the top face must be an < ellipse > because the markup uses cx, cy, rx, and ry; these attributes define an ellipse center point and horizontal/vertical radii. The diagonal marks on the left and right faces are straight segments, so they must use the SVG < line > element. A line is defined with starting coordinates x1, y1 and ending coordinates x2, y2. The first diagonal runs from the bottom point (200,365) to the upper-left point (50,100). The second diagonal must mirror it on the right side, so it starts at (200,365) and ends at (350,100). Therefore, the final coordinate selection is x2= " 350 " y2= " 100 " . References/topics:

                                NEW QUESTION # 25
                                Move the appropriate attributes from the list on the left to the correct descriptions on the right. You may use each attribute once, more than once, or not at all.
                                Note: You will receive partial credit for each correct match.

                                Answer:

                                Explanation:

                                Explanation:
                                pattern # Provides a way to set a regular expression that the value must match placeholder # Provides a way to set default text that displays until focus is placed in an element required # Provides a way to set form elements as mandatory multiple # Provides a way to allow more than one file or email address in a single input The correct matches are based on standard HTML5 form validation and input-attribute behavior. The pattern attribute defines a regular expression that the input value must satisfy before the form can be submitted successfully. It is commonly used for structured values such as phone numbers, codes, postal formats, or custom identifiers. The placeholder attribute supplies short hint text inside an input field, helping the user understand the expected value before entering data. The required attribute makes a form control mandatory; if the field is empty, constraint validation prevents successful submission. The multiple attribute allows a single input to accept more than one value, specifically for controls such as input type= " file " and input type= " email " , where users may upload multiple files or enter multiple email addresses. The maxlength attribute is not used in these matches because it limits the maximum number of characters that can be entered, but none of the listed descriptions asks for character-length restriction. References/topics: HTML5 form attributes, constraint validation, pattern, placeholder, required, multiple, input validation.


                                NEW QUESTION # 26
                                You need to contain overflowing text inside the element ' s border without creating unneeded scrollbars or losing text. Which attribute setting should you use?

                                Answer: D

                                Explanation:
                                The correct setting is overflow: auto;. The requirement is precise: the text must remain inside the element's border, must not be lost, and scrollbars should not appear unless they are needed. overflow: auto satisfies all three requirements because it clips overflowing content to the element's box and creates scrollbars only when the content actually exceeds the available space. This preserves access to all text while avoiding unnecessary horizontal or vertical scrollbars when the content fits. overflow: hidden is incorrect because it clips the overflowing text and provides no scrolling mechanism, meaning some content may become inaccessible.
                                overflow: visible is incorrect because the extra text can flow outside the element boundary, violating the requirement to keep content inside the border. overflow: scroll is close but not optimal because it forces scrollbars even when they are not required, which directly conflicts with the instruction to avoid unneeded scrollbars. References/topics: CSS overflow, scroll containers, text containment, content clipping, layout flow.


                                NEW QUESTION # 27
