💰 Tip Calculator – Simple and Handy Utility Tool

The Tip Calculator is a lightweight web application built with HTML, CSS, and JavaScript that allows users to quickly calculate the tip amount and total bill based on a given percentage. It's ideal for real-life use cases such as dining out or splitting bills.

This project was created to enhance my skills in form handling, user input validation, and basic arithmetic logic using JavaScript. It also helped improve my ability to build clean and centered UIs with CSS.
