Karan-raut7/Expense-tracker ? reverse-engineered prompt

Build me a responsive expense tracker that works well on desktop and mobile.

I want a simple page where a user can add income and expenses, see their current balance, and quickly understand where their money is going. It should have a clean layout, an input area for entering a title and amount, and a list of transactions that updates right away when something is added or removed. Make the totals easy to read, with separate sections for income, expenses, and overall balance.

Keep the design modern but minimal, and make sure the app feels polished with good spacing, readable text, and clear buttons. Use plain HTML, CSS, and JavaScript, and keep everything in one small app that is easy to run by opening the HTML file. If you need to check anything, look up current docs online.
