What's the easiest way to create a slide bar?

Question

I tried creating one but I'm having a problem with the transition (in CSS).

Answer 1

You can use already made code from any open source platform. 😉

Or you can learn more about transition to be able to fix the error you faced. 👏

Or you can provide more details about your error and I'll help you in fixing it. 😇

Good Luck
