Early Hints vs. Resource Hints vs. Speculation Rules: Which is right for what, and when? Comparing three similar, but quite different, "pre-fetch" techniques, explaining how they are similar, how they are different, when each should be used, and how together they create a powerful performance trio.

@comicss.art Oh, cool, will give it a try again later today! I also had a couple times where I would type and suddenly got thrown to the top, or some other random place, so my continued typing would overwrite stuff... 😂

Honestly, not that fun on my laptop keyboard either, seems to throw me all over the place sometimes... but also not sure how I would recommend fixing it... Having to click every "next" box would be annoying... :-? Really, really cool, though! :-)

Doesn’t `performance.getEntriesByType("navigation")[0].type` already offer that? Would be “reload”, no? Or too convoluted / separated?

Not knocking your demo, @matuzo.at, but never understood these progress trackers… doesn’t the scroll bar already do that?? 🤣

This would be a great addition to every CMS, as a page is published/updated, right before it is cached! 🥰

Investigating… can CLS cause a high LCP? Speedcurve’s Page Speed Benchmarks reported Costco.com's LCP averaging at 6.85s. But could it be that CLS is at least part of the problem? Read to find out!

Home page update After YEARS of the same design and having only a blogroll as my home page, I decided to add a landing page in front. Things are likely to change, but would love to hear what you think so far!
