Tracking users via CSS
What extra data can you track using this method over just normal HTTP logging?The only things I can think of are how a user interacts with a page - I don't particularly think this is too concerning - although as with all these things there are possibly much more creative uses of it that I haven't considered.There's a new image property loading="lazy" which generally will load an image when it approaches the viewport.  This could also be "abused" in similar ways.If this does turn out to be a privacy concern, browser settings/privacy addons could simply load all lazy images or images refered to in CSS/JS files on load which would nullify this technique.
