                                NEW QUESTION # 19
                                Which three methods are associated with the HTML5 localStorage API? Choose 3.

                                Answer: A,B,C

                                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. References/topics: Web Storage API, localStorage, Storage interface, application state, persistent key-value data.


                                NEW QUESTION # 20
                                You need to ensure that the value of an input element is a valid 10-digit phone number with no symbols. The input element should initially display all zeroes, but that value should never be stored with the form.
                                Complete the markup by selecting the correct option from each drop-down list.

                                Answer:

                                Explanation:

                                Explanation:
                                < input id= " phone "
                                pattern= " [0-9]{10} "
                                placeholder= " 0000000000 " >
                                The correct first attribute is pattern because the requirement is to validate the entered value against a specific format: exactly ten numeric digits and no symbols. The regular expression [0-9]{10} means that only digits from 0 through 9 are allowed, and exactly ten of them must be entered. This prevents values such as 123-456-
                                7890, (123)4567890, or 123 456 7890 because those contain symbols or spaces. The correct second attribute is placeholder, not value, because the input should initially display all zeroes but that displayed text must not be submitted or stored with the form. A placeholder is hint text shown when the field is empty; it disappears when the user enters real data and is not submitted as the control's value. By contrast, value= " 0000000000 " would actually prepopulate the input and could be submitted if the user did not change it. The required option is not selected because the question focuses on format validation and display hint behavior, not mandatory completion. References/topics: HTML5 form validation, pattern, regular expressions, placeholder, input constraint validation.


                                NEW QUESTION # 21
                                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 # 22
                                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: A

                                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 # 23
                                Review the grid container requirements and mockup on the left. Which markup should you use to define the grid container?

                                Answer: B

                                Explanation:
                                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.
