Turning On Combine & Minify CSSThe setting to enable this feature in ProductCart is under:
Settings > Store Settings > Store & Display Settings > Miscellaneous]> scroll to bottom
Your CSS is minified.
Note: if you have customized the related CSS and JS files, you should re-combine the files using one of the Developer Tools buttons found at the bottom of the Troubleshooting Utility page (Help > Troubleshooting Utility).
If those tests pass, then it's working on your store. Page Speed improvements (on Google's Tool) from minification and bundling seem to range from 2 to 15 points in our experience.
Keep in mind however, that there are other tests worth more points, and which have a greater impact on your site's Page Speed. E.G.:
- Image Optimization
Results from the Caching, Compression, and Image Optimization can be worth as much as 40 - 50 points. These things must all be done outside of ProductCart (using the web.config and/or image software).
