@smes this refers to the fact that if you have the “Minification” for CSS in “Basic Options” tab applied from Breeze, along with “Group Files” for “CSS” from “Advanced Options”, then Asset CleanUp will not trigger any minify/combined CSS feature to avoid any conflicts and using extra resources. The same thing applies to JavaScript settings. If you want to use minify/combine from Asset CleanUp, that’s fine, but don’t have the same settings enabled in Breeze.
Also, if you use the preload feature in Asset CleanUp and you want to keep those files preloaded, then Breeze grouping of the files will cancel that. Asset CleanUp instead is combining the CSS files, except for the preloaded ones (if any) as they were marked for preloading for a reason.
The same thing applies for “async” and “defer” in case you use the Pro version. Asset CleanUp checks if these tags are applied and don’t combine the files as you used “defer” for a reason.
So, if you have 10 CSS files and you decide to preload 3 of them for any reason, Asset CleanUp will combine 7 of them into one file and leave those preloaded 3 uncombined. THat’s if you used the Asset CleanUp features. If you want to stick with Breeze’s combining feature, it will ignore the preload and combine all 10 CSS files. The thing is the preload LINKs will still be there and the browser will print an error in the console that the preloads were useful. This won’t affect the functionality of your website at all, but it’s inconvenient to have extra calls made by the browser as you want to offer the best user experience to your visitors.
Hope it helps! Let me know if I can further assist you at your earliest convenience!
