Change color of progress bar in intervals in every 20%

Please help me create a progress bar where user will input interval in milliseconds.
The progress bar will change color in every 20%, let’s say at first 20% bar will be blue, then at 40% will be green, 60% will be yellow, 80% will be orange and 100% will be red.

What I did so far:

(Bootstrap preferred)

Thank you very much!

Firstly, welcome to the forums.

While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:

Thank you.
Let me Edit my post and show what I was able to do so far

you may need to explain more what should happen. as an user I have no idea what happens there

Ignore the first 2 input fields (Start and End).
User will input interval (in milliseconds) in the 3rd field.
The progress bar should start filling up in the given interval and in every 20% color of the bar should change; starting from blue, then green, yellow, orange and finally red.

how it should fill up? what happens in an interval?

I don’t know much about progress bar to be honest.
but I am guessing we have to increase width by 20% in every interval

I mean visually, what do you want to happen.
let’s say the user write 20ms. what happens every 20ms?

I was able to solve it.
You can check it out in the pen I posted.
