 How to create an awesome download progress animation using HTML, CSS and JS


Hello Everyone 👋 Welcome to My New Blog. Today I'll be sharing a beautiful animation of download progress with the help of HTML ,CSS and JavaScript 😍

I am Aaditya, sharing interesting project and topics daily. You can follow me up on my Instagram handle @_foxstack_


Preview of project:


Now let's proceed towards development of the project. 😄 First, I have provided HTML (index.htm) then JavaScript (script.js) and finally CSS (style.css)
