Hello @FlackoCodes

For updating the inputs to red color border, you need to inject a class to it like .error-input when the error occurs. When the input is fine, then the .error-input class should be removed. Then in your css apply the respective css property to that .error-input class.

I have also worked on a similar project where I need to validate my inputs and display the errors accordingly for the inputs. I used React and Styled components for the project. Refer to my Input.jsx.

Hope it helps you in solving your issue.

You have several problems, like:

• you allow users to put negative numbers
• you need to separate the code into smaller and more handle functions, you can do this by using custom hooks

I will make you a PR to solve those problems. Have a good day
