CSS file not refreshing in browser

Question

When I make any changes to my CSS file, the changes are not reflected in the browser. How can I fix this?

Answer 1

Having this problem before I found out my own lazy solution (based on other people suggestions). It should be helpful if your contents go through php interpreter.

To force downloading file every time you make changes to it, you could add file byte size of this file after question mark sign at the end.

EDIT: As suggested in comments, filemtime() is actually a better solution as long as your files have properly updated modify time (I, myself, have experienced such issues in the past, while working with remote files):
