Proposal: Just-In-Time Block CSS #2076
Description
Feature Description
For Block themes, WP modularizes and serves only the stylesheets needed for the blocks actually on the page, which is great! But it serves them all in the <head> tag, which is not as great, because all of them become render blocking even if their corresponding blocks are below-the-fold.
Would it be possible to modify the output of each CSS file to be enqueued just before the first instance of its relevant block? That way, the CSS for my social icons block in the footer doesn't have to be parsed before my hero cover block is rendered.
