Would you like to improve the CSS delivery of your WordPress site?
The visual layout and style of your WordPress website is controlled by CSS files. However, if your CSS code isn’t supplied properly, it could cause your website to slow down.

We’ll show you two simple ways to optimize your WordPress CSS delivery in this article.

The Impact of CSS Delivery on WordPress Performance

The visual design of your WordPress site is defined by CSS files. A CSS stylesheet file is included with your WordPress theme, and some of your plugins may also employ CSS stylesheets.

CSS is required for modern websites, however depending on how they’re set up, CSS files might slow down your site’s speed and performance.

Even a minor slowdown in site speed degrades the user experience and may have an impact on your search rankings and conversions, resulting in lower traffic and revenues.

CSS files can cause your website to load slowly if they must be loaded before the page can be shown. This means that until the CSS file loads, your visitors will see a blank page. Render-blocking CSS is the term for this.

CSS files can also slow down your website if they contain more code than is required to show the visible portion of the current page. Because of the additional code, they will take longer to load.

The good news is that by optimizing the way CSS code is sent, you may increase the performance of your WordPress site.

This is accomplished by determining the bare minimum of CSS code required to display the current web page’s initial section. This is referred to as critical CSS.

This critical code is then placed directly to the HTML of the page, rather than in separate stylesheets, so that the code can be rendered without first loading the CSS file.

After your visitors have seen the page’s content, the rest of the CSS can be loaded. This is referred to as ‘deferred loading.’
