My only reservation was knowing that, because the images are defined in CSS rather than HTML, their outgoing requests won’t start until the browser has created the Render Tree: it’s not until all the CSS has been downloaded, parsed, and the CSSOM constructed that the browser actually knows This div with this class is currently visible on the page and its background is set to be this image: I’d better download it! we can’t download a background-image until we’ve built the CSSOM).

A little while back, I mentioned I was doing some research for the book about how images are downloaded when media queries are involved. The same as with the first test: every browser tested, aside from Opera Mini and Opera Mobile, will download the image. With the exception of the over-eager Fennec, every tested browser only downloads the image when needed. which dominates the Android marketshare, still downloads both images as does Fennec and the Kindle.

Unfortunately if you’re not careful, this can lead to multiple images being downloaded even when they aren’t being used. A few people—including Jason Grigsby , Greg Rewis and Aaron Mentele —have done some excellent testing about how images are downloaded when media queries are involved. The property (which appears to be well supported) returns true if the image has been requested and downloaded, and false otherwise.

CSS is critical to rendering a page—a browser will not begin rendering until all CSS has been found, downloaded, and parsed—so it is imperative that we get it onto a user’s device as fast as we possibly can. download any CSS needed for the current context (medium, screen size, resolution, orientation, etc.) with a very high priority, blocking the Critical Path, and; download any CSS not needed for the current context with a very low priority, completely off of the Critical Path.

Generally speaking, increased bandwidth is only particularly useful when you’re transferring or downloading large files.

Preload is a bit of a blunt instrument—whatever you apply to it is gonna jump way up in line to be downloaded. If CSS is still being downloaded, inline scripts won’t run until that CSS arrives. That already puts us in a better state: the network priorities now line up much better with the actual importance of the assets being downloaded, and we’ve eliminated that inline script block.

With the oversized-images policy in place, large images are still downloaded, but placeholders are shown instead, and an error is logged to the console. Without those in place, the browser has no idea how much space the image should take up until the image has actually been downloaded. While unsized-media would potentially reduce layout shifting, the other policies still result in the images being downloaded, so the sole benefit is this increased visibility.

The thing about JavaScript is you end up paying a performance tax no less than four times: The cost of downloading the file on the network. The cost of parsing and compiling the uncompressed file once downloaded. There is no faster (pun intended) way to slow down a site than to use a bunch of JavaScript. The cost of executing the JavaScript. The memory cost. The combination is very expensive. And we are shipping an increasingly high amount.

For example, if you think of a large video file and imagine how long it might take to download the whole file. For example, if we needed to download a large file, process it, and keep it in memory, this could become a problem.
