Explanation:
First blank: display: grid;
Second blank: grid-template-columns: auto auto auto auto;
Third blank: grid-gap: 10px;
The layout shown is a CSS Grid layout with eight items arranged into four equal-width columns and two rows. The first required declaration is display: grid;, which turns the .grid-container element into a grid container. The second declaration is grid-template-columns: auto auto auto auto;, which defines four columns, matching the four visible boxes in each row: Mickey, Minnie, Luna, and George on the first row, then Bilbo, Bella, Madeline, and Groucho on the second row. The third declaration is grid-gap: 10px;, which creates spacing between the grid cells, matching the visible blue gaps around each item. The background-color:
#336699; creates the blue container background, while padding: 10px; adds space around the outer edge of the grid. The child rule .grid-container > div styles each grid item with a light background, centered text, padding, and larger font size.

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

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.

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.
