stores the generated global CSS inside a <code>global.css<\/code> file that is loaded on the front end using WordPress&#8217; standard stylesheet system.<\/li>\n\n\n\n<li><strong>Inline<\/strong> &#8211; outputs the generated CSS directly inside the page HTML instead of loading it from a separate stylesheet.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>File<\/strong> option is the recommended mode for most websites. Because the generated styles are served as a regular CSS file, they can be cached by browsers, CDNs and compatible optimisation systems instead of being included again inside every page response.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Inline<\/strong> option can be useful in specific environments or troubleshooting scenarios, but generally offers fewer caching benefits and requires the generated styles to be included directly in each page.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Disable Emojis Script<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress includes additional scripts and styles for its legacy emoji compatibility system. On modern browsers, this compatibility layer is generally unnecessary.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Enabling <strong>Disable Emojis Script<\/strong> prevents those additional WordPress emoji assets from loading, reducing unnecessary front-end requests.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Store Gravatars Locally<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Store Gravatars Locally<\/strong> option caches Gravatar images used by your website and serves the cached versions from your own server instead of requesting them directly from the external Gravatar service each time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This can be particularly useful on websites with active comment sections or other areas that display many user avatars, as it can reduce repeated third-party requests.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Image Lazy Load<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Blocksy can apply the browser&#8217;s native image lazy-loading mechanism to supported images generated by the theme. Lazy-loaded images are deferred until they are closer to entering the visitor&#8217;s viewport instead of all being prioritised immediately during the initial page load.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Image Lazy Load<\/strong> controls let you enable or disable this behaviour for specific image locations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Post\/Page Title Featured Image<\/strong> &#8211; controls lazy loading for featured images displayed inside the title or hero area of individual posts and pages.<\/li>\n\n\n\n<li><strong>Single Post\/Page Featured Image<\/strong> &#8211; controls lazy loading for the separate Featured Image element displayed on individual posts and pages.<\/li>\n\n\n\n<li><strong>Archives Featured Image<\/strong> &#8211; controls lazy loading for featured images displayed inside archive post cards.<\/li>\n\n\n\n<li><strong>Related Posts Featured Image<\/strong> &#8211; controls lazy loading for thumbnails displayed by the Related Posts module.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-palette-color-8-color has-palette-color-1-background-color has-text-color has-background is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"is-style-info coblocks-alert-paragraph wp-block-paragraph\"><strong>Performance optimisation works best in layers<\/strong><br>Blocksy already loads many of its assets only when they are required.
