Title: Async JS and CSS Author: dmikam Published: August 25, 2013 Last modified: November 18, 2013 --- Search plugins This plugin **hasn’t been tested with the latest 3 major releases of WordPress**. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://s.w.org/plugins/geopattern-icon/async-js-and-css.svg) # Async JS and CSS By [dmikam](https://profiles.wordpress.org/dmikam/) [Download](https://downloads.wordpress.org/plugin/async-js-and-css.zip) * [Details](https://wordpress.org/plugins/async-js-and-css/#description) * [Reviews](https://wordpress.org/plugins/async-js-and-css/#reviews) * [Installation](https://wordpress.org/plugins/async-js-and-css/#installation) * [Development](https://wordpress.org/plugins/async-js-and-css/#developers) [Support](https://wordpress.org/support/plugin/async-js-and-css/) ## Description When your page is loaded by browser – all that stuff placed in HEAD tag is loaded before the page content – in blocking way. So the content is delivered to user in the last moment, after all javascript and css files are loaded. If you are a webmaster or just want to make your web to make better your positions on search engines (yes, they preffer faster webs), just take a look on Google PageSpeed Insights – you’ll see that one of the mos important things is fastenes and one of the reason why your page is not so fast – is “Render-blocking JavaScript and CSS”. This plugin makes ALL scripts loaded by other plugins to be loaded in asynchronous way just like Google PageSpeed Insights recommends. All CSS files will be inserted inline into the document code or moved from the document beginning to the end, just before closing BODY tag (or just where you placed wp_foot() function). There are various methods to do that – they are all in plugin’s configuration page. Plugin makes all scripts to be loaded asynchronously using wp_enqueue_script and also can detect scrips included inside of wp_head and wp_footer hooks. All CSS files loaded using wp_enqueue_style can be loaded just before closing BODY tag by four methods: ``` * inserting tag * inserting * generating tag with javascript after all have loaded * inserting ALL CSS CODE INLINE into the document (the fastest way) ``` I was inspired to create this small plugin by Asynchronous Javascript but it works in completely different way. ### Known incompatibilities ``` * Internet Explorer 7 - Some scripts could be loaded impropertly (trying to fix it) * Plugin - WP JetPack - Share - everithing works but "More" dropdown menú * Plugin - Google Analyticator

Upload `asyncJSandCSS` folder to the `/wp-content/plugins/` directory 2. Activate the plugin through the 'Plugins' menu in WordPress 3. Configure the plugin if needed (Settings/Async Settings) ``` Plugin can affect only those files loaded using worpdress’s queue (using wp_enqueue_script and wp_enqueue_style), so if you include your CSS file inserting into head.php of your theme – it WILL NOT be affected and will be loaded in standart render-blocking way. ## FAQ Installation Instructions Like any other plugin ``` 1. Upload `asyncJSandCSS` folder to the `/wp-content/plugins/` directory 2. Activate the plugin through the 'Plugins' menu in WordPress 3. Configure the plugin if needed (Settings/Async Settings) ``` Plugin can affect only those files loaded using worpdress’s queue (using wp_enqueue_script and wp_enqueue_style), so if you include your CSS file inserting into head.php of your theme – it WILL NOT be affected and will be loaded in standart render-blocking way. What can I do with a “Leverage browser caching” warning in Google’s PageSpeed Insights ? You just need to include cache configuration in your .htaccess file. For example: ``` ExpiresActive On ExpiresByType image/gif "access plus 6 month" ExpiresByType image/jpeg "access plus 6 month" ExpiresByType image/png "access plus 6 month" ExpiresByType application/javascript "modification plus 1 month" ExpiresByType text/css "modification plus 1 month" ``` Errors with jQuery Add this line to exceptions box: ``` jquery ``` or if you are using jQuery from Google Hosted Libraries, you need to put: ``` jquery.min.js ``` Colorbox is not working Add this line to exceptions box: ``` colorbox colorbox-wrapper ``` ## Reviews ![](https://secure.gravatar.com/avatar/36d6704be939e898756a33ecd38cce84133516dbbab1b3e14de11362d527781b? s=60&d=retro&r=g) ### 󠀁[good plugin](https://wordpress.org/support/topic/good-plugin-3000/)󠁿 [lanuevareligiondt](https://profiles.wordpress.org/lanuevareligiondt/) August 3, 2018 nice job ![](https://secure.gravatar.com/avatar/82ef3b3f4a18a2f1b476d8986eb82874d44604d3c4832b0ac655953d84ff03ea? s=60&d=retro&r=g) ### 󠀁[Crashed page](https://wordpress.org/support/topic/crashed-page/)󠁿 [wpprup](https://profiles.wordpress.org/wppraesenz/) May 19, 2017 This plugin crashed many functions in my Divi page. The worst thing of it all is that the page did not get restored by neither deactivating the functions nor the whole plugin! Plus, the last support answer is one year old so there was obviously no hope for help. It was the first time ever I had to replay a backup of my site which is absolutely recommended to make before you install this troublesome plugin IMHO. I would warn from using this plugin after my experiences. ![](https://secure.gravatar.com/avatar/e6893c1e136a85aceee1e85c7bce822bd8e899d988c0ef7679e77fe929d2c930? s=60&d=retro&r=g) ### 󠀁[Very good plugin](https://wordpress.org/support/topic/very-good-plugin-233/)󠁿 [Abhishek Ghosh](https://profiles.wordpress.org/abhishek_ghosh/) October 14, 2016 Does the job and helps to do more tweaks. ![](https://secure.gravatar.com/avatar/1e19ac6519e9e980496c8016529eb47d4ad74c3477475fb40ee701c834aafb0e? s=60&d=retro&r=g) ### 󠀁[Disables the slider](https://wordpress.org/support/topic/disables-the-slider/)󠁿 [Holyto](https://profiles.wordpress.org/holyto/) September 3, 2016 Giving it 1 star because it breaks the site, especially the Revslider.
