If you're experiencing a caching issue, it could be related to CSS. Caching can sometimes behave strangely with CSS files, and the usual CTRL + F5 shortcut may not always work. A better alternative is to hold down the SHIFT key while clicking on the refresh symbol.
To prevent caching problems in CSS, consider adding a version number or a backslash to the file path for the CSS reference. For example, you can use:
<link rel="stylesheet" type="text/css" href="style.css?v2 />
.
Using a version number is helpful for indicating updates to the CSS file and ensures that the browser recognizes it as a different file, prompting it to reload the CSS.
If you have access to a server-side language like PHP, you can automatically force the browser to refresh the CSS every time the page loads by appending a timestamp within the link to the CSS file. Here's an example:
<link rel="stylesheet" type="text/css" href="style.css?<?php echo date('l jS \of F Y h:i:s A'); ?>" />
Remember that excessive reloading of CSS can impact performance, so it's advisable to remove the timestamp when transitioning to a production environment to allow visitors to cache the CSS.
I hope this information proves useful! :)
