Load original CSS files
Some JavaScript creates or updates CSS selectors on interaction. Enabling this option will inject a page’s original CSS files upon user interaction. This can resolve some JavaScript related issues while still reducing initial page load times.
Parse all CSS files
Autoptimize settings allow you to exclude certain CSS files from optimization. By default, RapidLoad will exclude them as well.
When you enable the Parse all CSS files option, RapidLoad will find and remove unused CSS in all CSS files on the page - even those that have been excluded from Autoptimize.
Inline small CSS files
Enable this setting and RapidLoad will convert any files smaller than 5kb into inlined CSS. Inlining small CSS files reduces the number of requests and can further improve performance metrics like Time to First Contentful Paint.
Query Strings
RapidLoad ignores query strings by default. This means that /order and /order?id=123 are considered the same URL and generate only one Optimization Job. Enabling the Query Strings setting tells RapidLoad to consider URLs with query strings as separate URLs and generate an Optimization Job for each of them.
Note: On sites that dynamically create many URLs with query strings, like Woocommerce, enabling this option will greatly increase the number of jobs in the queue.
Other Options
Minify
Enable the Minify option to have RapidLoad minify and remove remaining comments from the final, optimized CSS files.
CSS Variables
Many themes, plugins, and external libraries define CSS variables. In some cases, unused CSS variables can be safely removed for additional savings in file size. Results may vary. We strongly recommend testing this option on a staging site before enabling it in a production environment.
CSS Animation Keyframes
Some themes and plugins globally load full animation libraries that are mostly unused. Enable this option to find and remove unused animation keyframes.
CSS @font-face rules
Many themes, plugins, and external libraries include @font-face rules for multiple fonts that go unused. In some cases, unused @font-face rules can be safely removed for additional savings in file size. Results may vary. We strongly recommend testing this option on a staging site before enabling it in a production environment.
Cache Busting
If your jobs are triggering "Clear the page cache" warnings, try enabling this option. With Cache Busting enabled, RapidLoad circumvents stale caches by appending random query strings while it crawls.
Debug Mode
If you need additional information about job statuses, warnings, or failures, enabling Debug Mode will make RapidLoad logs available for review. Check the box for Debug Mode and save your settings. A “View Logs” link will now display next to the option and will open a modal with searchable logs.
