Though the plugin only async. * > And no, I have not specifically integrated it with cache plugins others than > rocket and what I maintain. Has not been a huge need yet. * Understandable! * Can I have concatenate and minify on while using this together with criticalcss. com API? Does this work with criticalcss plugin? and does it cater and work for mobile as well if two separated cache files are using and using different styles for mobile and desktop. Based on web standards and media queries. Wonder so that criticalcss does not break any responsiveness. * Plugin Author [Derrick Hammer](https://wordpress.org/support/users/pcfreak30/) * (@pcfreak30) * [7 years, 10 months ago](https://wordpress.org/support/topic/pre-install-question-11/#post-10610145) * Yes, if you disable minify setting it will disable my plugin as it “replaces” wp-rockets minify. It will ignore any concat setting and do it anyways. * my critical css works perfectly fine with this and wp-rocket. Will work in mobile too, though problems should be directed at criticalcss.com support first. * Thread Starter [Rookie](https://wordpress.org/support/users/alriksson/) * (@alriksson) * [7 years, 10 months ago](https://wordpress.org/support/topic/pre-install-question-11/#post-10613238) * Ok but you say I can have everything enable in WP rocket all is then good and how it should be, right? * Ok good, but it disabled the critical css pre-build in wp-rocket then or? * Plugin Author [Derrick Hammer](https://wordpress.org/support/users/pcfreak30/) * (@pcfreak30) * [7 years, 10 months ago](https://wordpress.org/support/topic/pre-install-question-11/#post-10613270) * wp-rocket critical css does not work with my critical css plugin * Thread Starter [Rookie](https://wordpress.org/support/users/alriksson/) * (@alriksson) * [7 years, 10 months ago](https://wordpress.org/support/topic/pre-install-question-11/#post-10614877) * Ok just leave that box empty then. * Anyhow does this plugin work without wp rocket it does right? * **Adding critical css would solve the:** * Prioritize visible content _Your page requires additional network round trips to render the above-the-fold content.

Is it combining all inline css and create a file of it? Tried it out on staging which breaks most styling parts. Both from theme and customize css. * Plugin Author [Derrick Hammer](https://wordpress.org/support/users/pcfreak30/) * (@pcfreak30) * [7 years, 8 months ago](https://wordpress.org/support/topic/pre-install-question-11/#post-10726232) * Yes it merges inline css as well in the order it is outputted with all other CSS. * Thread Starter [Rookie](https://wordpress.org/support/users/alriksson/) * (@alriksson) * [7 years, 8 months ago](https://wordpress.org/support/topic/pre-install-question-11/#post-10726310) * Ok I think I know why it breaks since parent style.css overrides it. Due to wordpress and theme css selectors hierarchy. Which makes the site look strange since this css file then becomes secondary and not first in order. Like it is when inlining in wordpress css.
