HTML Lazy loading
Image Lazy loading
Critical CSS
This is a valid White Hat SEO page speed optimisation strategy but is not always working as it should. It is entirely dissimilar to the image lazy loading concept and allows rendering the HTML page using an inline CSS without waiting to load the full range of external CSS files. Unresolved issues:Deferred JavaScript
The HTML attribute script “defer” was introduced to ensure that the JS script would not run until the browser had loaded the web page. This way, you can ensure that no blocking assets prevail, preventing parsing CSS and rendering the page. Google checks that JS defer is adequately implemented and will advise if this is not the case. LiteSpeed Cache and other leading caching plugins provide a further possibility to select between the After DOM Ready and Deferred options for inline JS to fine-tune its parsing in the browser. All external JS files are set to the Deferred option by default. Unresolved issues:Hey WebWhim,
