Animated progress bar in React

Below I present you my solution for a simple progress bar with some styling 📊🎨.

In this solution I use:

  • useState hook to store the progress bar's state,
  • content width measured in percents according to the container - that trick lets us display progress from 0% to 100% in an easy way,
  • some example buttons that trigger setProgress() method to demonstrate how the progress bar works (animation between switching has a nice effect).

Practical example:
