How browsers REALLY load Web pages dives into the wild world of resource loading, showing how browsers juggle render/parsing blockers, preload scanners, resource hints (preload, preconnect), loading modifiers (async, defer, module), fetchpriority and responsive images. You’ll see why no two browsers behave the same—some even intentionally stall certain requests until other resources finish downloading—and why blindly slapping fetchpriority=high on everything is a recipe for disaster.
Through a series of real page-load waterfalls, Robin Marx breaks down why each browser makes its weird choices and reveals practical tweaks to make sure your most important assets—like that hero image—land ASAP. Walk away armed with insider knowledge of modern HTTP/2 and HTTP/3 tricks, plus strategies to tame all those browser quirks and loading gotchas.
