Smart Adsense Calculator:

1. Structure:
   • The page contains a container that holds all the form inputs and the result display.
   • The inputs for Impressions, CPC (Cost Per Click), and CTR (Click Through Rate) are required for the calculation.
   • A button triggers the calculation, and the result is displayed below the button.
2. Styling:
   • The design uses a gradient background with blue and green tones.
   • The form fields are styled to be user-friendly and aligned with modern web standards.
   • The button changes color on hover, enhancing the user experience.
   • The design is responsive, meaning it adapts well to both mobile and desktop screens.
3. Calculation:
   • The calculation is straightforward: it calculates clicks by multiplying Impressions with CTR and then calculates the earnings by multiplying the result by the CPC.
   • If the user inputs invalid data (like leaving any field empty), it displays an error message.
4. Responsive Design:
   • The @media query in the CSS ensures that on smaller screens (e.g., mobile devices), the layout adjusts accordingly to make it easier to use.

Features:

• Mobile-Friendly: The design is fully responsive and adjusts to mobile screens.
• Easy Calculation: Users simply enter the required values, and the result is calculated instantly.
• User-Friendly UI: The design is clean, modern, and has clear labels and input fields.
