• New in Chrome 73 | Web | Google Developers

  "Dark mode for Chrome's UI is now supported on Mac, and Windows support is on the way. In addition, there's work on a CSS media query: prefers-color-scheme, that can be used to detect if the user has requested the system use a light or dark color theme."

• Microsoft proves the critics right: We're heading toward a Chrome-only Web | Ars Technica

  "Last week, Microsoft made a major update to the Web version of its Skype client, bringing HD video calling, call recording, and other features already found on the other clients. And as if to prove a point, the update works only in Edge and Chrome. Firefox, Safari, and even Opera are locked out."

• patrickhulce/third-party-web: Data on third party entities and their impact on the web.

  "This document is a summary of which third party scripts are most responsible for excessive JavaScript execution on the web today."

• Why can't I set the font size of a visited link?

  "In theory, there is no way that a web page can determine whether a link has been colored differently. One possibility is a timing attack: say, if it takes longer to color something pink compared to blue, the page could measure how long it took to render the element, and compared this to an expected duration."

• CSS Nesting Module

  "This module introduces the ability to nest one style rule inside another, with the selector of the child rule relative to the selector of the parent rule. This increases the modularity and maintainability of CSS stylesheets."

• Making Sense of Chrome Lite Pages - TimKadlec.com

  "Please, please, please only use Cache-Control: no-transform if you are already checking for the Save-Data header and optimizing the experience accordingly (or if your initial experience is already blazingly fast and lightweight). Users explicitly telling us they want a faster experience is the kind of direct feedback we don't usually get, and respecting their request is important."

• Chromium Blog: Chrome Lite Pages - For a faster, leaner loading experience

  "These optimizations are only applied when the loading experience would be painful to users. Specifically, they are applied when the network's effective connection type is "2G" or "slow-2G," or when Chrome estimates the page load will take more than 5 seconds to reach first contentful paint given current network conditions and device capabilities."
