Here are my examples for forcing the web browser to display your most current updates for CSS Files, Normal Images and your Background images. Remember you will need to change the version numbers each time you want your new changes to be forced to everyone viewing your app or web page.
Test Code Examples:
<link rel="stylesheet" href="test.css?v=1234">
<img src="images/test.jpg?v=1234" alt="Test">
background: url(../images/test.png?v=1234);
Advanced Automated CSS:
<link rel="stylesheet" href="css/test.css?<?=filemtime('css/test.css');?>">Again, just change the ?v=1234 to a new number like ?v=1235
