WPT compliance rose by 54,590 passing subtests to 1,565,597 total. The team completed its WebDriver implementation, began importing WPT tests directly, parallelized internal tests, and switched CI builds to ReleaseWithDebugInfo+Sanitizers. Repainting was overhauled to a pull model synced to 60fps. Input events and contenteditable handling improved enough to support Discord chat. WebAudio gained decodeAudioData support, CSS gained filter effects, lab()/lch()/color() functions, basic CSS nesting with the & selector, and expanded clip-path shapes. The post closes with the first pizza ever ordered through the Ladybird browser. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What new CSS features did the Ladybird browser add in October 2024? Ladybird added support for the CSS filter property (blur, drop shadows, grayscale, hue rotation), the lab(), lch(), and color() functions for extended color spaces, basic CSS nesting using the & selector, and expanded clip-path shapes including inset(), xywh(), rect(), circle(), ellipse(), and fill-rule support. _Track emerging browser engine feature support like this on daily.dev before relying on it in production._ ### Does Ladybird support CSS nesting with the & selector? Yes, basic support for CSS nesting using the & selector was added, letting style rules be grouped inside a parent selector instead of repeated separately, such as writing hover and child selectors nested inside an anchor tag rule. Support for nesting @media queries inside rules was announced as coming next. _Developers comparing browser support for modern CSS nesting can follow progress like this on daily.dev._ ### How many Web Platform Tests does the Ladybird browser pass? Ladybird passed 1,565,597 Web Platform Tests subtests as of October 2024, an increase of 54,590 over the prior month. The WebDriver implementation now covers all endpoints required by the specification, enabling more WPT tests that simulate user interaction to run against the engine. _Engineers evaluating alternative browser engines can watch standards-compliance milestones like this on daily.dev._ --- Tags: [#css](https://daily.dev/tags/css) [View this post on daily.dev](https://daily.dev/posts/this-month-in-ladybird-rmmtp0txb) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"This Month in Ladybird","url":"https://daily.dev/posts/this-month-in-ladybird-rmmtp0txb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/this-month-in-ladybird-rmmtp0txb"},"datePublished":"2026-08-31T05:54:38.870Z","dateModified":"2026-08-31T05:55:54.020Z","description":"Ladybird's October 2024 update covers 378 merged PRs from 72 contributors, two new sponsors (JetBrains, Jonathan Lahijani), and two new board members (Tim...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/f0d04d597be9efdaf11883698ad30378?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/f0d04d597be9efdaf11883698ad30378?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Ladybird Browser","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Ladybird Browser","logo":"https://media.daily.dev/image/upload/s--gBOjamNh--/f_auto,q_auto/v1788155675/logos/ladybird?_a=BAMAMicg0","url":"https://daily.dev/sources/ladybird"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/this-month-in-ladybird-rmmtp0txb","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"css","timeRequired":"PT5M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Ladybird Browser","item":"https://daily.dev/sources/ladybird"},{"@type":"ListItem","position":3,"name":"This Month in Ladybird"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/this-month-in-ladybird-rmmtp0txb#faq","mainEntity":[{"@type":"Question","name":"What new CSS features did the Ladybird browser add in October 2024?","acceptedAnswer":{"@type":"Answer","text":"Ladybird added support for the CSS filter property (blur, drop shadows, grayscale, hue rotation), the lab(), lch(), and color() functions for extended color spaces, basic CSS nesting using the & selector, and expanded clip-path shapes including inset(), xywh(), rect(), circle(), ellipse(), and fill-rule support.
