# August in Servo: CSS Grid, text selection, and more!
*Plus accessibility and navigation improvements.*
> The Servo project's monthly update covering Servo 0.6.0 and 417 commits landed in August: CSS Grid enabled by default, new web platform features and DOM APIs, text selection, accessibility, navigation and session-history fixes, a SpiderMonkey upgrade, embedding API changes and performance work.
[**Servo 0.6.0**](https://github.com/servo/servo/releases/tag/v0.6.0) contains all of the changes we landed in August, which came out to **417 commits**!
The big news is that we’ve turned on support for **CSS Grid** by default ([@nicoburns](https://github.com/nicoburns), [#45621](https://github.com/servo/servo/pull/45621)).
This has had a huge positive impact on the visual appearance of many websites!
[](https://servo.org/img/blog/2026-10-gary.png)
We’ve shipped several new web platform features:
- **touch-action** ([@yezhizhen](https://github.com/yezhizhen), [#47043](https://github.com/servo/servo/pull/47043))
- **animation-composition** ([@nicoburns](https://github.com/nicoburns), [#47405](https://github.com/servo/servo/pull/47405))
- **color-scheme** ([@TimvdLippe](https://github.com/TimvdLippe), [#47042](https://github.com/servo/servo/pull/47042))
- **full-width**, **math-auto**, **full-size-kana** values for **text-transform** ([@SimonSapin](https://github.com/SimonSapin), [#47160](https://github.com/servo/servo/pull/47160), [#47160](https://github.com/servo/servo/pull/47160), [#47225](https://github.com/servo/servo/pull/47225))
Plus a bunch of new DOM APIs:
- **requestAnimationFrame()** on **DedicatedWorkerGlobalScope** ([@Taym95](https://github.com/Taym95), [#46232](https://github.com/servo/servo/pull/46232))
- **ancestorOrigins** on **Location** ([@TimvdLippe](https://github.com/TimvdLippe), [@mrobinson](https://github.com/mrobinson), [#46056](https://github.com/servo/servo/pull/46056))
- **imagesrcset** and **imagesizes** on `` ([@lumiscosity](https://github.com/lumiscosity), [@TimvdLippe](https://github.com/TimvdLippe), [#47103](https://github.com/servo/servo/pull/47103))
- **style** on **CSSFontFaceRule** ([@simonwuelker](https://github.com/simonwuelker), [#47388](https://github.com/servo/servo/pull/47388))
- **isReloadNavigation** and **isHistoryNavigation** on **Request** ([@Taym95](https://github.com/Taym95), [@yezhizhen](https://github.com/yezhizhen), [#46917](https://github.com/servo/servo/pull/46917))
- **name=color-scheme** on `` ([@TimvdLippe](https://github.com/TimvdLippe), [@jdm](https://github.com/jdm), [#46993](https://github.com/servo/servo/pull/46993))
- **focusin** and **focusout** events ([@RichardTjokroutomo](https://github.com/RichardTjokroutomo), [@yezhizhen](https://github.com/yezhizhen), [#46980](https://github.com/servo/servo/pull/46980))
- **new TextEvent()** ([@moamenhesham0](https://github.com/moamenhesham0), [@mrobinson](https://github.com/mrobinson), [#47391](https://github.com/servo/servo/pull/47391))
- **PeriodicWave** and **createPeriodicWave** on **BaseAudioContext** ([@kevlu93](https://github.com/kevlu93), [#47492](https://github.com/servo/servo/pull/47492))
This release also contains significant improvements to **navigation**, **document loading**, and **session history**, which are some of the [gnarliest](https://html.spec.whatwg.org/multipage/browsing-the-web.html#navigation-and-session-history) parts of the HTML specification. Who knew that loading `about:blank` was [so complicated](https://hsivonen.fi/about-blank/)? The upshot to all this work is that pages that open additional windows or include iframes work much more reliably.
This is another big update, so here’s an outline:

- [**New contributors**](#new-contributors)
## Security
We upgraded to **SpiderMonkey v153**, which brings many new security and crash fixes to Servo’s JavaScript engine integration ([@sagudev](https://github.com/sagudev), [@Gae24](https://github.com/Gae24), [#47489](https://github.com/servo/servo/pull/47489)).
Navigating away from a document that **activated fullscreen mode** now exits fullscreen mode ([@shubhamg13](https://github.com/shubhamg13), [@jdm](https://github.com/jdm), [#47123](https://github.com/servo/servo/pull/47123)).
## Real world compat
CSS Grid enabled by default means that many websites with traditional grid layouts now look correct, like [rustweek.org](https://servo.org/blog/2026/10/09/august-in-servo/rustweek.org).
v0.5.0
v0.6.0
[2026.rustweek.org](https://2026.rustweek.org/)
It also makes a lot of websites look better that you wouldn’t assume rely on CSS Grid:
v0.5.0
v0.6.0
[labs.jensimmons.com](https://labs.jensimmons.com/)
Panning gestures initiated by touch inputs now lock to the dominant axis ([@yezhizhen](https://github.com/yezhizhen), [#46983](https://github.com/servo/servo/pull/46983)).
This results in more predictable panning when interacting with pages in Servo.
We fixed a crash affecting [gumroad.com.au](https://gumroad.com.au) ([@lumiscosity](https://github.com/lumiscosity), [#47266](https://github.com/servo/servo/pull/47266)).
We’re interested to hear how well your favourite websites run in Servo! Report successes in [this Zulip thread](https://servo.zulipchat.com/#narrow/channel/263398-general/topic/Servo.20web.20compat.20success.20stories/with/612898341), and failures [in our GitHub issues](https://github.com/servo/servo/issues).
## Work in progress
**Accessibility support** in Servo continues to make great strides; it can be enabled with the `--pref accessibility_enabled` command line argument.
Servo now reports **positions and sizes** for items in the content accessibility tree ([@philocalyst](https://github.com/philocalyst), [@alice](https://github.com/alice), [@mrobinson](https://github.com/mrobinson), [#46996](https://github.com/servo/servo/pull/46996)), allowing macOS VoiceOver to work more reliably.
We also report many [**ARIA roles**](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Reference/Roles) for web content elements to accessibility toolkits ([@mukilan](https://github.com/mukilan), [#47318](https://github.com/servo/servo/pull/47318)).
Full list of supported roles
- alert
- banner
- blockquote
- caption
- code
- complementary
- contentinfo
- definition
- deletion
- directory
- document
- emphasis
- feed
- figure

- list
- log
- main
- math
- navigation
- none
- note
- paragraph
- presentation
- rowgroup
- search
- status
- strong
- term
- time
- timer
Servo’s support for **Document.execCommand()** is rapidly improving, and can be enabled with `--pref dom_exec_command_enabled`.
We fixed issues with the **inserttext** command ([@Psychpsyo](https://github.com/Psychpsyo), [#47224](https://github.com/servo/servo/pull/47224), [#47306](https://github.com/servo/servo/pull/47306)), editing uneditable content ([@Psychpsyo](https://github.com/Psychpsyo), [#47362](https://github.com/servo/servo/pull/47362)), computing contained nodes ([@TimvdLippe](https://github.com/TimvdLippe), [#47429](https://github.com/servo/servo/pull/47429)), adjusting selections in **contenteditable** ([@mrobinson](https://github.com/mrobinson), [#47393](https://github.com/servo/servo/pull/47393), [#47581](https://github.com/servo/servo/pull/47581), [#47581](https://github.com/servo/servo/pull/47581)), and implemented the **indent** and **insertLineBreak** commands ([@Psychpsyo](https://github.com/Psychpsyo), [#47416](https://github.com/servo/servo/pull/47416), [#47445](https://github.com/servo/servo/pull/47445)).
We made a lot of progress on the **LargestContentfulPaint** performance metric, implemented behind the `--pref largest_contentful_paint_enabled` argument.
Servo now supports the **element** and **loadTime** attributes, ([@shubhamg13](https://github.com/shubhamg13), [#46553](https://github.com/servo/servo/pull/46553), [#47475](https://github.com/servo/servo/pull/47475)), URLs for video element posters ([@shubhamg13](https://github.com/shubhamg13), [#43376](https://github.com/servo/servo/pull/43376)), accurate size information ([@shubhamg13](https://github.com/shubhamg13), [#43378](https://github.com/servo/servo/pull/43378)), and painting text nodes ([@shubhamg13](https://github.com/shubhamg13), [#47212](https://github.com/servo/servo/pull/47212)).
There was preparatory work for a future [**AudioWorklet**](https://developer.mozilla.org/en-US/docs/Web/API/AudioWorklet) implementation ([@niyabits](https://github.com/niyabits), [#46856](https://github.com/servo/servo/pull/46856), [#47016](https://github.com/servo/servo/pull/47016), [#47199](https://github.com/servo/servo/pull/47199)).
See Niya’s [blog post](https://text.tchncs.de/niya/wrapping-up-my-work-on-servos-audioworklet) about her Outreachy project for more details!
We’re continuing work on the **ServiceWorker** feature, which can be enabled with `--pref dom_serviceworker_enabled`.
This month we implemented the **CookieStore** interface behind the `--pref dom_cookiestore_enabled` command line argument ([@Taym95](https://github.com/Taym95), [#47044](https://github.com/servo/servo/pull/47044)) as well as the **Cache** interface ([@gterzian](https://github.com/gterzian), [#47220](https://github.com/servo/servo/pull/47220)).
Servo now supports a **disk-backed HTTP cache** that can be enabled with `--pref network_http_disk_cache` ([@Narfinger](https://github.com/Narfinger), [#43819](https://github.com/servo/servo/pull/43819)).
This cache persists between runs, but there is not yet any way to clear it.
## Embedding API
**Breaking change:** [`WebView`](https://doc.servo.org/servo/struct.WebView.html)::`toggle_sampling_profiler` has been removed ([@lumiscosity](https://github.com/lumiscosity), [#47014](https://github.com/servo/servo/pull/47014)).
To perform sampling profiling on Servo, follow the instructions in [the book](https://book.servo.org/contributing/profiling.html).
**Breaking change:** The variants of [`MouseButton`](https://doc.servo.org/servo/enum.MouseButton.html) have been renamed to `Primary`, `Secondary`, and `Auxiliary` ([@mrobinson](https://github.com/mrobinson), [@SimonSapin](https://github.com/SimonSapin), [#47327](https://github.com/servo/servo/pull/47327)).
We’ve added several new Cargo features reflecting common usage patterns:
- `default_web_features`, to include optional web platform features in the build (e.g. WebXR and WebGPU) ([@jschwe](https://github.com/jschwe), [#44032](https://github.com/servo/servo/pull/44032))
- `bundled`, to include required resources in the binary ([@jschwe](https://github.com/jschwe), [#44032](https://github.com/servo/servo/pull/44032))
- `brotli-compression-stream`, enabling support for `brotli` content in the `CompressionStream`/`DecompressionStream` web APIs ([@Narfinger](https://github.com/Narfinger), [@jdm](https://github.com/jdm), [#47197](https://github.com/servo/servo/pull/47197))
- `webcrypto`, to enable support for the Crypto and WebCrypto web APIs ([@Narfinger](https://github.com/Narfinger), [#47198](https://github.com/servo/servo/pull/47198))
- `webgl`, to enable support for WebGL ([@janeoa](https://github.com/janeoa), [#47200](https://github.com/servo/servo/pull/47200))
## For users and developers
One visible change is that interactive **text selection** now works!
This is the result of lots of work across our script and layout code to ensure it respects the actual geometry of the page content ([@mrobinson](https://github.com/mrobinson), [@SimonSapin](https://github.com/SimonSapin), [#47022](https://github.com/servo/servo/pull/47022), [#47025](https://github.com/servo/servo/pull/47025), [#47329](https://github.com/servo/servo/pull/47329), [#47358](https://github.com/servo/servo/pull/47358), [#46982](https://github.com/servo/servo/pull/46982), [#47425](https://github.com/servo/servo/pull/47425), [#47438](https://github.com/servo/servo/pull/47438), [#47437](https://github.com/servo/servo/pull/47437), [#47581](https://github.com/servo/servo/pull/47581), [#47070](https://github.com/servo/servo/pull/47070), [#47048](https://github.com/servo/servo/pull/47048), [#46963](https://github.com/servo/servo/pull/46963)).
[](https://servo.org/img/blog/2026-10-select.png)
Building Servo now requires at least **Clang 19** on all platforms ([@jschwe](https://github.com/jschwe), [#47421](https://github.com/servo/servo/pull/47421)).
Additionally, the `cargo-ohos` tool is now required for building for OpenHarmony ([@jschwe](https://github.com/jschwe), [#47334](https://github.com/servo/servo/pull/47334)).
Debug builds on Windows can now complete successfully ([@jschwe](https://github.com/jschwe), [#47372](https://github.com/servo/servo/pull/47372)).
Linux arm64 builds have been customized to work on **Raspberry Pi 5** ([@mukilan](https://github.com/mukilan), [#47113](https://github.com/servo/servo/pull/47113)).
Any libservo embedders targeting the same platform will require a similar change if they are using jemalloc.
### servoshell
Under **Wayland** and **OpenHarmony**, we now integrate with the system clipboard ([@TheZoq2](https://github.com/TheZoq2), [@yezhizhen](https://github.com/yezhizhen), [@jschwe](https://github.com/jschwe), [#46938](https://github.com/servo/servo/pull/46938), [#47177](https://github.com/servo/servo/pull/47177)).
The macOS command key and Windows logo key is now reported as `Meta` instead of `Super` ([@eachra-bawn](https://github.com/eachra-bawn), [#47330](https://github.com/servo/servo/pull/47330)).
The **Android** port has had many rough edges filed off as part of modernizing it for the **Compose UI** ([@veyndan](https://github.com/veyndan), [#47656](https://github.com/servo/servo/pull/47656), [#47491](https://github.com/servo/servo/pull/47491), [#47494](https://github.com/servo/servo/pull/47494), [#47697](https://github.com/servo/servo/pull/47697), [#46955](https://github.com/servo/servo/pull/46955), [#47644](https://github.com/servo/servo/pull/47644), [#47652](https://github.com/servo/servo/pull/47652), [#47276](https://github.com/servo/servo/pull/47276), [#47277](https://github.com/servo/servo/pull/47277), [#47299](https://github.com/servo/servo/pull/47299), [#47439](https://github.com/servo/servo/pull/47439)) and converting its implementation to Kotlin ([@veyndan](https://github.com/veyndan), [#46926](https://github.com/servo/servo/pull/46926), [#46925](https://github.com/servo/servo/pull/46925), [#46951](https://github.com/servo/servo/pull/46951), [#46965](https://github.com/servo/servo/pull/46965)).
Library consumers are no longer responsible for implementing **pause and resume** support ([@veyndan](https://github.com/veyndan), [#47555](https://github.com/servo/servo/pull/47555)).
Meanwhile, the **OpenHarmony** port now supports external keyboards with US keyboard layouts ([@jschwe](https://github.com/jschwe), [#47359](https://github.com/servo/servo/pull/47359)).
Additionally, there are now better fallback font selections for CJK characters ([@RichardTjokroutomo](https://github.com/RichardTjokroutomo), [#47116](https://github.com/servo/servo/pull/47116), [#47664](https://github.com/servo/servo/pull/47664)).
Setting the `device_pixel_ratio_override` preference is no longer ignored on Android and OpenHarmony ([@jschwe](https://github.com/jschwe), [#47081](https://github.com/servo/servo/pull/47081)).
## Performance and stability
There were many small changes this month that **removed unnecessary allocations** ([@Narfinger](https://github.com/Narfinger), [@jschwe](https://github.com/jschwe), [@yezhizhen](https://github.com/yezhizhen), [#47264](https://github.com/servo/servo/pull/47264), [#47147](https://github.com/servo/servo/pull/47147), [#47066](https://github.com/servo/servo/pull/47066), [#47249](https://github.com/servo/servo/pull/47249), [#47249](https://github.com/servo/servo/pull/47249), [#47285](https://github.com/servo/servo/pull/47285), [#47307](https://github.com/servo/servo/pull/47307), [#47343](https://github.com/servo/servo/pull/47343), [#47361](https://github.com/servo/servo/pull/47361), [#47395](https://github.com/servo/servo/pull/47395), [#47427](https://github.com/servo/servo/pull/47427), [#47454](https://github.com/servo/servo/pull/47454), [#47474](https://github.com/servo/servo/pull/47474), [#47506](https://github.com/servo/servo/pull/47506), [#47479](https://github.com/servo/servo/pull/47479), [#47530](https://github.com/servo/servo/pull/47530), [#47541](https://github.com/servo/servo/pull/47541), [#47566](https://github.com/servo/servo/pull/47566), [#47509](https://github.com/servo/servo/pull/47509), [#47622](https://github.com/servo/servo/pull/47622)).
We also **reduced GC interactions** leading to better JS performance ([@jdm](https://github.com/jdm), [@Narfinger](https://github.com/Narfinger), [@webbeef](https://github.com/webbeef), [@TimvdLippe](https://github.com/TimvdLippe), [@mrobinson](https://github.com/mrobinson), [#47513](https://github.com/servo/servo/pull/47513), [#47250](https://github.com/servo/servo/pull/47250), [#47158](https://github.com/servo/servo/pull/47158), [#47165](https://github.com/servo/servo/pull/47165), [#47049](https://github.com/servo/servo/pull/47049), [#47251](https://github.com/servo/servo/pull/47251), [#47510](https://github.com/servo/servo/pull/47510), [#46981](https://github.com/servo/servo/pull/46981)).
On platforms that memory map font data (such as OpenHarmony and macOS), we can now save time that would otherwise be spent loading font files from disk ([@jschwe](https://github.com/jschwe), [#47029](https://github.com/servo/servo/pull/47029)).
Similarly, reading system fonts is no longer in the critical path of starting up the engine ([@Narfinger](https://github.com/Narfinger), [@jdm](https://github.com/jdm), [#46476](https://github.com/servo/servo/pull/46476)).
There were were also a number of savings in the final binary size ([@jschwe](https://github.com/jschwe), [@kkoyung](https://github.com/kkoyung), [@Narfinger](https://github.com/Narfinger), [@jschwe](https://github.com/jschwe), [#47211](https://github.com/servo/servo/pull/47211), [#47214](https://github.com/servo/servo/pull/47214), [#47210](https://github.com/servo/servo/pull/47210), [#46950](https://github.com/servo/servo/pull/46950)).
We **fixed crashes** related to media playback ([@calvaris](https://github.com/calvaris), [#46891](https://github.com/servo/servo/pull/46891)), the 2d canvas renderer ([@yezhizhen](https://github.com/yezhizhen), [#46915](https://github.com/servo/servo/pull/46915)), fonts with negative line gaps ([@jschwe](https://github.com/jschwe), [#47374](https://github.com/servo/servo/pull/47374)), and resolving fonts variants ([@simonwuelker](https://github.com/simonwuelker), [#47356](https://github.com/servo/servo/pull/47356)).
Canvas renderer worker threads can now be adjusted by the `thread_pool_canvas_workers` preference, allowing more performance granularity according to embedder needs. ([@jschwe](https://github.com/jschwe), [#46691](https://github.com/servo/servo/pull/46691), [#47018](https://github.com/servo/servo/pull/47018))
We’ve continued our long-running effort to use the Rust type system to make Servo’s integration with SpiderMonkey **safer and more reliable** ([@jdm](https://github.com/jdm), [@treetmitterglad](https://github.com/treetmitterglad), [@Narfinger](https://github.com/Narfinger), [@Gae24](https://github.com/Gae24), [#47398](https://github.com/servo/servo/pull/47398), [#47296](https://github.com/servo/servo/pull/47296), [#47051](https://github.com/servo/servo/pull/47051), [#47005](https://github.com/servo/servo/pull/47005), [#47323](https://github.com/servo/servo/pull/47323), [#47297](https://github.com/servo/servo/pull/47297), [#47322](https://github.com/servo/servo/pull/47322), [#47368](https://github.com/servo/servo/pull/47368), [#47446](https://github.com/servo/servo/pull/47446), [#47317](https://github.com/servo/servo/pull/47317)). We’re also working on statically preventing [a footgun](https://github.com/servo/servo/issues/39139) that can lead to uncollectible GC cycles and leaking memory ([@Gae24](https://github.com/Gae24), [#47355](https://github.com/servo/servo/pull/47355), [#47650](https://github.com/servo/servo/pull/47650)).
Historically, **about:memory** has reported all memory usage by Rust implementations of JS APIs as one undifferentiated `js/malloc-heap` number.
We now break it down by memory usage of nodes in document trees ([@pylbrecht](https://github.com/pylbrecht), [#46931](https://github.com/servo/servo/pull/46931)) and interfaces that are not part of the DOM ([@jdm](https://github.com/jdm), [#47531](https://github.com/servo/servo/pull/47531)). We also report memory usage for the network stack’s cookie database ([@Narfinger](https://github.com/Narfinger), [#47248](https://github.com/servo/servo/pull/47248)) and the canvas renderer backend ([@janeoa](https://github.com/janeoa), [@jdm](https://github.com/jdm), [#46958](https://github.com/servo/servo/pull/46958)).
We’ve added an **experimental threadboost** mechanism ([@jschwe](https://github.com/jschwe), [@mrobinson](https://github.com/mrobinson), [#46843](https://github.com/servo/servo/pull/46843), [#47027](https://github.com/servo/servo/pull/47027)) that has been observed to improve Speedometer results by **50%** and allow canvas rendering to reach 60 FPS.
This is initially enabled for OpenHarmony, but future expansion to other Linux-based platforms is expected.
## More on the web platform
We upgraded to [resvg 0.48](https://github.com/linebender/resvg/blob/main/CHANGELOG.md#0480-2026-07-31), fixing **many issues with SVG images** with missing width/height attributes that specified a `viewBox` ([@nicoburns](https://github.com/nicoburns), [#46937](https://github.com/servo/servo/pull/46937)).
Upgrading to [Taffy 0.14](https://github.com/DioxusLabs/taffy/blob/main/CHANGELOG.md#0130) fixed a number of **CSS grid-related crashes**, support for grid names, better intrinsic sizing, and improved performance ([@nicoburns](https://github.com/nicoburns), [#47031](https://github.com/servo/servo/pull/47031), [#47493](https://github.com/servo/servo/pull/47493)).
We also fixed some issues in the Taffy grid integration for more accurate baselines ([@nicoburns](https://github.com/nicoburns), [#47518](https://github.com/servo/servo/pull/47518)).
Session history traversals (i.e. navigating backwards or forwards in history) now wait for any outstanding traversal to complete ([@mrobinson](https://github.com/mrobinson), [#47293](https://github.com/servo/servo/pull/47293), [#47485](https://github.com/servo/servo/pull/47485)).
Meanwhile, navigations to `about:blank` are skipped if the initial about:blank document is present ([@jdm](https://github.com/jdm), [#47074](https://github.com/servo/servo/pull/47074)).
`about:blank` documents no longer use the asynchronous HTML parser ([@jdm](https://github.com/jdm), [#47050](https://github.com/servo/servo/pull/47050)), and no longer report a `readyState` of `LOADING` ([@mrobinson](https://github.com/mrobinson), [#47450](https://github.com/servo/servo/pull/47450)).
Opening auxiliary windows will wait to dispatch the load event until the initial `about:blank` document has [been replaced](https://html.spec.whatwg.org/multipage/document-sequences.html#windows%3Awindow) ([@jdm](https://github.com/jdm), [@mrobinson](https://github.com/mrobinson), [#47442](https://github.com/servo/servo/pull/47442), [#46975](https://github.com/servo/servo/pull/46975)).
For non-about:blank content, we also made the document loading phases more reliable ([@TimvdLippe](https://github.com/TimvdLippe), [@mrobinson](https://github.com/mrobinson), [#47426](https://github.com/servo/servo/pull/47426)), improved conformance of `javascript:` URL evaluation and navigation target selection ([@mrobinson](https://github.com/mrobinson), [#47486](https://github.com/servo/servo/pull/47486), [#47516](https://github.com/servo/servo/pull/47516)), and addressed longstanding compatibility issues with cross-origin `Window` and `Location` objects ([@mrobinson](https://github.com/mrobinson), [#47549](https://github.com/servo/servo/pull/47549)).
Our media playback has improved; we fixed several issues around **canPlayType()** on **HTMLMediaElement** that allow Servo to report that **MP4 content is playable** ([@jdm](https://github.com/jdm), [#47612](https://github.com/servo/servo/pull/47612), [#47641](https://github.com/servo/servo/pull/47641), [#47670](https://github.com/servo/servo/pull/47670)).
Input elements with the `autofocus` property inside of a `
