MuhammadMuzamil-dev/Calculator-Assignment ? reverse-engineered prompt

Build me a clean, working calculator web page that feels polished and easy to use.

I want a simple layout with a display at the top and buttons for numbers, basic math operations, clear, delete, and equals. It should work like a normal calculator, so I can click buttons or tap them on mobile and get the right result right away. Make the design look nice and modern, with good spacing, readable text, and a responsive layout that still works well on smaller screens.

Please keep it simple and make sure the buttons actually do the calculations correctly, including decimals and basic operator handling. If you need to look up anything current online, go ahead. Use the existing HTML, CSS, and JavaScript files and make it all run smoothly in the browser.
