I want to write an application that can detect whether a value in CSS file has changed or not, how can I do that ?

Please post example code / import as much as possible. Tkq

Do you change the values manually in a text editor, or do you have an application that automatically opens and edits the CSS file, or do you only change the values in memory to change the way the browser displays something. Please give us an example

I just want to check whether the value is the same after some time

A value doesn't just change itself over time.
It will be helpful to see how/when the values are changed.
