TLDR: Chrome 145 ships column wrapping for multi-column layouts, a new Origin API for safer origin comparisons, and Device Bound Session Credentials to protect against cookie theft. The DevTools update is equally substantial with MCP server improvements and significantly better performance profiling.

TLDR: Cloudflare now automatically converts HTML pages to markdown when AI agents request them with an Accept: text/markdown header. This reduces token usage by roughly 80% and introduces content negotiation as a first-class pattern for agent-readable web content.

TLDR: Since contrast-color() is only in Safari and Firefox so far, a clever CSS-only approximation using OKLCH lightness and round() gives you automatic black-or-white text selection in a single line: oklch(from var(--color) round(1.21 - L) 0 0). It closely matches APCA contrast calculations.

TLDR: Gwtar is a new polyglot HTML archival format that solves a long-standing trilemma: it is simultaneously static (self-contained), single-file, and efficient (lazy-loading) by using a JavaScript header that calls window.stop() and then serves assets via HTTP range requests into an appended tarball.

TLDR: Safari shipped text-wrap: pretty in 2025, but combining it with text-align: justify produces ugly results because the smart line-breaking algorithm targets a width slightly narrower than the container, and justification then inflates whitespace to fill the gap.

TLDR: The W3C published a new working draft of CSS Selectors Level 5, introducing pseudo-classes like :local-link, :interest-source/:interest-target, :blank, :heading(), time-dimensional selectors, the :state() pseudo-class for custom elements, and the column combinator.
