It targets a 4.5:1 text contrast ratio, can transform SVG colors and some simple monochrome bitmap logos, and leaves content images and canvas content untouched; masks and `mix-blend-mode` may be disabled if they cause problems. Developers can signal `color-scheme: light dark` with a meta tag to tell Safari not to manipulate the page's color scheme, even if the site does not actually support dark mode. The article notes Chrome had an auto dark mode origin trial, but provides no detailed comparison. ### Source excerpt Browsers are beginning to take responsibility for how websites look in dark mode, even when the websites themselves haven't implemented it. ## Release Notes for Safari Technology Preview 256 DevFeed: [Release Notes for Safari Technology Preview 256]() Original publisher: [Read original article]() Author: Jon Davis Published: 2026-11-05T00:09:57Z Content type: release Language: en Sources: [WebKit]() Topics: [Release notes](), [releases]() Tags: [macos](), [macos-golden-gate](), [preview](), [release](), [safari](), [safari-technology-preview]() ### AI overview Safari Technology Preview 256 is available for macOS Golden Gate and macOS Tahoe; installed copies can be updated in System Settings under General -> Software Update.

Lighthouse now uses Chrome's render-blocking status instead of request priority, and for text LCP painted with FCP it reuses the FCP dependency graph; both changes can remove work that previously appeared to delay painting. The release also revises connection, redirect, and network estimates. Calibre's simulated-throttling profiles adopted 13.6 on 31 October, while runtime-throttling profiles are unaffected by the two paint fixes; Chrome DevTools gets 13.6 with Chrome 159, so results may temporarily differ from PageSpeed Insights. Record test versions, mark upgrades on dashboards, compare like with like, and keep field data such as CrUX separate, since Lantern's model change does not alter it. ### Source excerpt Lighthouse 13.6 changes simulated FCP and LCP, so PageSpeed Insights scores can improve even when the page itself has not changed. ## iOS 27.3 Adds Vertical Tabs, Adaptive Dark Mode to Safari DevFeed: [iOS 27.3 Adds Vertical Tabs, Adaptive Dark Mode to Safari]() Original publisher: [Read original article]() Author: BeauHD Published: 2026-11-04T00:00:00Z Content type: release Language: en Sources: [Slashdot]() Topics: [Dark Mode](), [iOS]() Tags: [adaptive-dark-mode](), [apple-intelligence](), [dark-mode](), [ios-27-3](), [ipados-27-3](), [macos-golden-gate](), [safari](), [siri](), [vertical-tabs]() ### AI overview Safari's iOS 27.3, iPadOS 27.3 and macOS Golden Gate 27.3 updates add vertical tabs and Adaptive Dark Mode. Vertical tabs appear on the left, use icons by default, and can be widened to show site titles; they work with Topics and Tab Groups, and retain tab pinning and group switching. Adaptive Dark Mode offers to restyle bright websites when the user is browsing in Dark Mode, adjusting backgrounds, contrast, logos, graphics and shadows as needed for readability. It can be enabled for all sites or individually after use. It does not activate on sites with a native or already-dark design, and developers can opt a site out. The excerpt also says Siri browser controls will expand to organize tabs and clear site-specific history; answering questions across multiple open webpages is described as a later feature. ### Source excerpt Apple is adding vertical tabs and an Adaptive Dark Mode to Safari with iOS 27.3, iPadOS 27.3 and macOS Golden Gate 27.3. The December updates will also expand Siri's browser controls, including organizing tabs and clearing site-specific history, with a later feature allowing Siri to understand and answer questions about content across multiple open webpages. MacRumors reports: Vertical Tabs are located on the left side of the display and use icons by default to save space, but there is an option to make the tab bar wider to show website titles as well. Vertical Tabs work with both Topics and Tab Groups to keep things organized. Topics are created when automatic Apple Intelligence tab sorting is turned on in iOS 27. Pinning tabs by dragging, quickly swapping between Tab Groups, and other features also continue to work. [...] Apple is adding Adaptive Dark Mode for websites that don't have a dark mode design option by default. If you use Dark Mode and then browse to a website with a bright background color, Safari will offer an option to "Try" Adaptive Dark Mode. After tapping Try, Safari renders a Dark Mode version of the page that makes the background darker, changes text contrast, inverts logos and graphics, recolors vector artwork, lifts raised surfaces, and rebalances layered shadows. Each website will be adapted based on what's needed to make it readable, so not every tweak is applied to every site. You can opt to turn Adaptive Dark Mode on for all sites or on a site-by-site basis after using it. If a site has a native dark mode or has a dark design already, Adaptive Dark Mode won't activate. Developers can also add a tag that causes Safari to ignore Adaptive Dark Mode and show the website as the developer intended.

Safari leaves pages that declare `color-scheme: light dark` alone; otherwise it estimates whether a page is light or dark and transforms light pages. Its color matrix darkens light backgrounds and lightens text while preserving hue and aiming for WCAG 4.5:1 text contrast. Most images and all `
