An Age Calculator app using HTML, CSS and JavaScript

Hello everyone 👋🏽,

I am happy to announce that I have just completed yet another challenge. This challenge was not as working with dates in JavaScript can be tricky. My solution is responsive across all devices.

I learnt how to work with dates, perform JavaScript validation, and add animations to display the user's age on the UI. I also considered integrating leap years as well.
The users should be able to enter dates like 29/02/2020 but cannot enter dates like 29/02/2021 as the latter is not a leap year. However, rare people born in leap years can also get a more accurate calculation of their age 😃.

I am open to suggestions on how I can improve my code.

Thank you 🙏🏽
