hello guys here are my questions, Thank you in advance

• Does this section display properly on mobile?
• Is the task accessible to users with disabilities?
• Are the HTML and CSS elements used correctly?
• Is the code well-formatted and easy to read?
• Are there any redundant or unnecessary elements in the code?
• built with the mobile-first workflow, how did I do?
