Explanation:

  • The HTML document is structured using standard tags such as <html>, <head>, <title>, <body>, and <div>.
  • CSS styling is applied within <style> tags.
  • The .container class sets the width of the container to 500px.
  • The CSS selector p:first-child selects the first paragraph element within the container and sets its text color to #5ac4ed.
  • Similarly, p:last-child selects the last paragraph element within the container and sets its text color to #5ac4ed.
