                                NEW QUESTION # 29
                                What is the effect of applying the CSS float: right property to an image?

                                Answer: B

                                Explanation:
                                The correct answer is A. Applying float: right to an image removes the image from the normal inline flow and moves it to the right side of its containing block. Inline content, such as text, is then allowed to flow around the floated image. Because the image is anchored on the right, available text space is primarily on the left side of the image, and the text can continue above, beside, and below the floated region according to the surrounding layout. This is the classic use case for floating images within article-style content, where text wraps around a visual element rather than forcing the image to occupy an entire line. Option B is incomplete because it omits the important left-side wrapping behavior. Option C describes the opposite direction: an image floated left with text appearing to its right. Option D also describes float: left, not float: right.
                                References/topics: CSS float, floated images, text wrapping, normal flow, content positioning.


                                NEW QUESTION # 30
                                You need to create the layout shown, which defines five content areas:
                                * Logo and page title
                                * Menu
                                * Main content area
                                * Additional content area
                                * Copyright and contact information
                                You define the following classes:

                                Answer: B

                                Explanation:
                                The correct answer is D because the layout shown is a named-area CSS Grid layout. The mockup contains five semantic regions: the top header area for the logo and page title, a left-side menu, a central main content area, a right-side additional content area, and a bottom copyright/contact area. In CSS Grid, this type of visual structure is defined with grid-template-areas, where each quoted string represents one grid row and each repeated name represents how far that area spans across columns. In option D, heading spans the full top row, menu occupies the left column across the lower rows, content fills the main center region, right fills the additional content region, and contact spans the bottom row to the right of the menu. Option A only defines row and column sizes and does not name the five content areas. Options B and C are invalid for this purpose because named layout strings do not belong in grid-template-rows or grid-template-columns. References

                                NEW QUESTION # 31
                                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: B

                                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 # 32
                                You are given the design for an app. The project manager asks you to outline the steps you must take to release and maintain the app.
                                Move each step from the list on the left to its correct sequence in the application lifecycle on the right.
                                Note: You will receive partial credit for each correct response.

                                Answer:

                                Explanation:

                                Explanation:
                                Determine requirements # Develop code # Test the app
                                #
                                Monitor performance # Deploy the app
                                The correct application lifecycle sequence begins with Determine requirements because the team must first define what the app must accomplish, who will use it, and which functional and technical expectations must be satisfied. Since the question states that the design is already provided, the next implementation step is Develop code, where the HTML, CSS, JavaScript, assets, APIs, and app logic are created according to the approved design and requirements. After development, the app must be validated through Test the app.
                                Testing confirms that the app works correctly, meets requirements, handles user input properly, and does not contain functional defects that would block release. Once testing is complete, the app can be released through Deploy the app, which publishes it to the target environment or makes it available to users. The final operational stage is Monitor performance, where the released app is observed, maintained, updated, and improved based on performance, reliability, defects, and user behavior. References/topics: application lifecycle management, requirements, development, testing, deployment, maintenance.


                                NEW QUESTION # 33
                                Match each stage of Application Lifecycle Management to the task that occurs during that stage.
                                Move each stage from the list on the left to the correct task on the right.
                                Note: You will receive partial credit for each correct match.

                                Answer:

                                Explanation:

                                Explanation:

                                Application Lifecycle Management organizes website creation into ordered stages that move from intent to implementation and long-term support. The Plan stage comes first because it establishes why the website exists, who the audience is, and what goals the application must satisfy. The Design stage converts those requirements into structure, including page layout, navigation, interface organization, and visual arrangement.
                                The Develop stage is where the website is built by writing HTML markup, CSS styling, JavaScript behavior, and integrating required assets or APIs. The Test stage evaluates whether the completed website functions correctly and is usable according to requirements; this includes checking features, layout behavior, validation, and user workflows. The Deploy stage publishes the finished website to the target hosting or production environment so users can access it. Finally, the Maintain stage occurs after release and includes monitoring, updating, fixing defects, improving compatibility, and keeping content or functionality current. References
