Eliminating Unutilized Resources: Locating Unused Images and CSS Styles

Identifying unused assets in a website is crucial for optimizing performance and reducing bloat. While manual inspection can be time-consuming and unreliable, there are efficient methods to pinpoint these hidden elements.

To find unused images, Google Chrome offers a built-in tool accessible through the Developer Tools (F12). Navigate to "Audits" and select "Remove unused CSS rules." Chrome will scan the site and generate a report highlighting redundant CSS declarations for non-existent IDs and classes.

Furthermore, Chrome 59 introduces CSS and JS code coverage, providing detailed insights into which resources are actually loaded and utilized on the page. By enabling coverage analysis, developers can identify unused styles and scripts, allowing them to streamline their codebase.

By leveraging these techniques, developers can effectively remove unneeded images and CSS styles, optimizing website performance and enhancing user experience.
