What we need to do is make sure that each server response provides the correct HTTP headers to instruct the browser when and for how long to cache the requested resources Optimize your CSS We now know that the browser must wait for it to fetch and process the CSS code before it can render the page ( CSS blocks rendering ). But not all CSS resources are render-blocking . CSS can be adapted to particular conditions, and we can optimize it using media types and media queries. If you are viewing a web page on your screen, the browser will make a request for the print media type, but will not block page rendering for this resource. Take the following tag link: This tag's reference stylesheet applies under all conditions, regardless of the current media type, screen resolution, device orientation, etc.
This means that the CSS resource always blocks rendering. Fortunately, we can send Country Email List a request for a CSS resource under specific conditions. We could move the styles for printing to a separate file and use the attribute mediato tell the browser that the specified stylesheet should only be loaded when printing the page, and does not need to block rendering to the screen: Make sure your styles are actually needed to render the page. If they aren't, you could add an appropriate value to the tag's media attribute and unlock rendering. Media types and queries can help us speed up page rendering, but we can do much more. Minifying CSS : Whitespace and comments only help us read CSS declarations. By removing comments and whitespace from the style sheet we can significantly reduce the number of bytes in a CSS file Combining multiple CSS files : This would reduce the number of HTTP requests .
This action is especially important in mobile connections, where performance is affected by high latency ( learn more about latency ). Inline critical CSS : Some styles are critical in the sense that they are needed to render the page above the fold. You should always consider inserting critical inline styles directly into the HTML markup, to avoid additional HTTP requests. But avoid inlining large CSS files, because this may require additional round trips to render Above the Fold, and this will result in a PageSpeed warning. You can give your site a nice boost by minifying the code directly from your MyKinsta dashboard . Simply use the code minification function provided to enable automatic editing of CSS and Javascript with a simple click. The time it takes for the browser to layout the document depends on the number of DOM elements to layout and the complexity of the layout.
