Websites created with frameworks like Angular, React or Vue.js are becoming more and more popular, although it is more difficult to manage SEO.
It is part of technical search engine optimization which tries to index and analyze web pages created with this language more easily for Google Spider.
There are three steps to indexing: page analysis, rendering, and finally indexing.

With that in mind, the most common reason Google can’t access and render these files is usually because the user blocked the Googlebot for their Robots.txt file.

Allow: .css »
After checking these points, the indexing must be checked again using the Google Search Console. If you find pages on the website without being indexed, a manual re-indexing must be requested through the Google tool.
