                                IT Specialist HTML5 Application Development Sample Questions (Q43-Q48):

                                NEW QUESTION # 43
                                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.


                                NEW QUESTION # 44
                                You need to define a grid that meets the following requirements:
                                * Explicitly sets the width of 6 equal columns of 1 fraction
                                * Explicitly sets 5 varied sized rows
                                * Defines 15px of space between each grid column
                                * Defines 10px between each grid row
                                Complete the code by selecting the correct option from each drop-down list.

                                Answer:

                                Explanation:

                                Explanation:
                                display: grid;
                                grid-template-columns: repeat(6, 1fr);
                                grid-template-rows: 50px 50px 150px 150px 100px;
                                grid-gap: 10px 15px;
                                The correct grid definition starts with display: grid;, which turns the element into a CSS Grid container. To explicitly create six equal-width columns, the correct property is grid-template-columns, and the most efficient value is repeat(6, 1fr). The repeat() function avoids writing 1fr six separate times, while 1fr assigns each column one equal fraction of the available grid width. The five row sizes must be explicitly declared with grid-template-rows, using the exact varied values shown: 50px 50px 150px 150px 100px. This creates five rows with fixed pixel heights. For the spacing requirement, grid-gap: 10px 15px; is the correct shorthand.
                                The first value controls the row gap, so rows are separated by 10px; the second value controls the column gap, so columns are separated by 15px. References/topics: CSS Grid containers, explicit grid tracks, grid-template- columns, grid-template-rows, repeat(), fractional units, grid gaps.


                                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 markup segment creates an SVG ellipse?

                                Answer: A

                                Explanation:
                                The correct answer is D because an SVG ellipse is created with the < ellipse > element and the required geometry attributes cx, cy, rx, and ry. The cx attribute defines the x-coordinate of the ellipse's center point, and cy defines the y-coordinate of the center point. The rx attribute defines the horizontal radius, while ry defines the vertical radius. In option D, cx= " 200 " and cy= " 80 " correctly position the center of the ellipse, while rx= " 100 " and ry= " 50 " correctly define an ellipse that is wider than it is tall. Option A is invalid because the element name is misspelled as < ellipsp > , so the browser will not interpret it as an SVG ellipse.
                                Option B incorrectly uses x and y attributes instead of the ellipse-specific center and radius attributes. Option C correctly uses cx and cy, but incorrectly uses x and y where rx and ry are required. References/topics: SVG markup, < svg > container, < ellipse > element, center coordinates, horizontal radius, vertical radius.


                                NEW QUESTION # 47
                                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: C

                                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.
