These render-blocking resources delay the time for first contentful paint (FCP). files (JavaScript) in tags without async or defer attributes are a render-blocking resource.When (CSS) doesn’t have a disabled or media attribute matching the user’s device, it becomes a render-blocking resource.The browser’s time to download, parse, and execute these resources can increase the website’s loading speed. It has to download, parse, and execute each JavaScript (scripts), CSS (stylesheets), and HTML file. The time browser encounters JavaScript, HTML or CSS files it stops reading the page.

This is essentially causing a redundant delay as all of these CSS files load at once on the initial load. At a default setting, all of these things end up loading essentially at the same time with no prioritization. When someone visits a page on your website, there are many different pieces of that page that must load and render before they can use the page.
