Enhanced the Web-Development repo my added two new front-end projects. 1)SkyCat - weather Application - it is a weather app built using HTML, CSS, and js. It is responsive and user-friendly. This app shows accurate weather data and also has the functionality to auto-detect the user's location. I used OpenWeatherMap API to get weather data. The site will also generate random weather quotes. 2) Simple Calculator - I built a user friendly calculator app for performing basic maths operations .
