I was working on a simple HTML design. The IDE which I was using was a browser-based IDE named Codiad. I was trying it out. While I was working on a very simple design. For some reason whenever I made a change to the CSS it was not reflecting on the design I made. I was running the file directly from the live server. After spending some time I realized that my CSS was not getting reflected because the browser was using the cached file. I tried reloading the page with ctr+F5 but the CSS would not update. I searched the net for a solution but could not find a proper one so I just made a small hack in the CSS using PHP. This can be done using any scripting or programming language.
Below is the code:
<link rel="stylesheet" href="customStyle.css?v=<?php printf('%s.%s.%s',rand(),rand(),rand()); ?>">
Hope this might be useful for others searching for a solution.
