What does render blocking mean?

Post by Rina7RS »

Now for some tips on how to improve your page loading time.

File Optimization
Deleting render-blocking files
Removing render-blocking files has to be one of the best things you can do to improve your critical rendering path and important metrics like your First Contentful Paint (FCP). If there’s one thing you want to improve, put this at the top of your list!

Render blocking is when externally linked JS and CSS files prevent the browser from completing the HTML parsing and displaying the page content to the user.

When the browser parses the HTML and finds the externally linked CSS and JS files, it stops parsing the HTML and starts requesting, receiving, downloading, and parsing those files. Until those files are ecuador mobile database downloaded and parsed, the page will remain blank.

This can cause some pretty significant delays, especially if the download size of the CSS or JS is large.

There are several important steps to solve this problem:

1. Inline critical CSS
To fix this, the first thing you need to do is inline any critical CSS in the <head> of your page. As you might have guessed, critical CSS is the CSS that is required to display above the fold content to the user.

When this CSS is inlined at the very top of the page in the <head>, the browser will parse it and then apply it to any HTML it finds before it gets to your render-blocking files.
