In this challenge, you will develop a responsive pricing section with a single tier according to the provided designs for different device types - mobile, tablet, and desktop.

Implementation requirements

• Design fidelity: Aim to follow the design as closely as possible. All elements in the design should be present, using the specified text color, font size, font weight, spacing, dimensions, etc.
• Interactivity:
  • Button states: Implement and style buttons to reflect different states - normal, hover, focus, and disabled.
• Responsive behavior:
  • Text size: Should be responsive; font size is larger for wider devices, smaller for narrow devices.
  • Responsive layout: The content should stack vertically on smaller screens and align horizontally as the screen width increases.
• Placeholders: You may leave the redirection links empty for any unspecified buttons or links.
• Cross-browser compatibility: Check that your solution works for major browsers including Chrome, Firefox and Safari.
• [Stretch goal] Performance optimization: Code for fast load times with efficient CSS and JavaScript techniques.
• [Stretch goal] Accessibility compliance: Follow best practices for web accessibility, such as using semantic HTML and ARIA roles where necessary, using proper alt tags for images and ensuring that buttons and links can be navigated to and selected using keyboard controls.
