Is the website displaying outdated styles that have been deleted from the CSS file?

While I am no stranger to html and css, bootstrap 4 is a new venture for me. After applying only a background color to the .container in my stylesheet successfully, things took an unexpected turn.

Despite spending hours creating the page's structure, adding a border to an element yielded no results in my css file. Exhausting all troubleshooting options like cache clearing, hard refreshes, browser restarts, and validation checks resulted in no change.

The mysterious persistence of the background color even with every style removed from my css file led to confusion. Deleting the entire css file finally forced a reevaluation, revealing that the empty file still somehow retained the background color. A fresh start with a new stylesheet proved to be the solution.

What caused this bizarre occurrence, and how can I avoid it in the future?

Answer №1

It appears that there may be a caching problem, specifically with the CSS cache.

Keep in mind that simply doing a standard hard refresh with CTRL + F5 does not clear the CSS cache; this action reloads the page but retains cached content. To fully clear the CSS cache, you can try one of the following methods:

  • CTRL + SHIFT+ R
  • SHIFT + F5
  • Hold down SHIFT while clicking on the refresh icon

An alternative solution is to trick your page into thinking it's loading a different CSS file. This can be achieved by either renaming the file or adding a query string at the end (e.g. style.css?v=1).

You can dynamically add the current timestamp to your CSS file using a back-end language, forcing the browser to reload the CSS file every time the page loads if desired. Keep in mind that while this may resolve update issues, it could slightly impact performance.

I hope this information proves helpful! :)

Answer №2

The problem you're experiencing seems to be related to cached data. To resolve it, try clearing your browser's cache.

You can do this by using the keyboard shortcut ctrl+shift+r
