All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-emulated screenshot is pixel-identical in appearance to the light capture, and the structure probe reports computed colorScheme “light”. CANVA-001 medium: The public landing page does not adapt to the user’s dark color-scheme preference. |
respect-user-preferencesrespects-reduced-motion | issues | high | Under prefers-reduced-motion: reduce, getAnimations() returned 42 running animations, each with 1400 ms duration and an infinite iteration count (serialized as null). CANVA-002 high: Continuous hero motion remains active when reduced motion is requested. |
respect-user-preferencesrespects-contrast | pass | medium | Lighthouse accessibility scored 100 and color-contrast passed on the rendered homepage; the UI remained legible across sampled screenshots. |
implement-natural-interactionsview-transitions | issues | high | Rendered DOM/CSS inspection found no view-transition-name or ::view-transition usage across the homepage snapshot, while the page presents carousels, menus and cross-page journeys. CANVA-015 low: State and route changes do not expose View Transition styling on the sampled public pages. |
implement-natural-interactionsscroll-driven-animations | pass | medium | Rendered CSS contained animation-timeline declarations; layout/trace evidence found no sustained scroll task problem on the sampled landing page. |
implement-natural-interactionsphysical-gestures | pass | medium | Rendered CSS contained scroll-snap and overscroll-behavior rules for carousel/scroll surfaces, providing platform-native gesture behavior. |
provide-guided-navigationscroll-state-aware-chrome | pass | medium | Desktop and mobile screenshots show compact, persistent navigation chrome that maintains orientation without covering the primary heading. |
provide-guided-navigationanchored-positioning | pass | medium | No tooltip-style floating anchored surface was present in the sampled first-load states; menus did not visibly drift or clip. |
provide-guided-navigationdirects-attention | pass | medium | The landing and detail screenshots use a single prominent heading/CTA, and the presentation detail includes a Home > Presentations breadcrumb. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | Desktop and mobile screenshots show the cookie panel covering roughly half the viewport and hiding the primary call to action/content on home, templates, presentation and pricing pages. CANVA-003 medium: The first-load cookie panel obscures most of the primary content on every sampled marketing page. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The rendered DOM contains zero dialog and zero popover elements while the screenshot shows a blocking overlay. CANVA-004 medium: The blocking consent overlay is not exposed with a native dialog or popover primitive. |
maximize-content-reduce-noisereduced-chrome | pass | medium | Screenshots show border-light content-led layouts with a compact header; outside consent, decorative visuals support the product message. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | medium | At 360x800, home and templates reported scrollWidth 360, clientWidth 360 and zero horizontal overflow; viewport metadata is present. |
adapt-to-the-form-factorcomponent-level-responsiveness | pass | medium | DOM/CSS inspection found an @container rule, and 360px evidence shows components reflow without horizontal overflow. |
adapt-to-the-form-factorinput-modality-aware | pass | medium | Lighthouse target-size passed; focus probing found native/3px focus treatments on representative links and controls. |
support-core-task-successclear-purpose-and-primary-action | pass | medium | The first viewport states “Bring your ideas to life” and exposes “Start creating”; detail/listing pages have specific H1s. |
support-core-task-successprimary-flow-completion | pass | medium | Representative navigation targets for templates, presentation creation, pricing and help all loaded successfully with clear continuation controls. |
support-core-task-successclear-system-state-and-recovery | pass | medium | The sampled invalid sitemap endpoint rendered a branded roadblock state with a “Go to home” recovery link and error identifier. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse measured LCP 4.168 s, FCP 3.31 s and TTI 7.241 s; the first-party trace corroborated two long tasks and 92.97 ms total blocking time. CANVA-006 high: Throttled load performance misses the good LCP range. |
be-fast-and-stablevisual-stability | issues | high | The 360x800 layout observer measured CLS 0.2157, including a 0.21285 shift at about 6.18 seconds, above the 0.1 good threshold. CANVA-005 high: The mobile templates listing has poor visual stability. |
be-fast-and-stableefficient-main-thread | pass | medium | First-party trace measured only two long tasks and 92.97 ms TBT; Lighthouse TBT was 93 ms, within the good range. |
be-fast-and-stableefficient-resource-delivery | pass | medium | Assets were compressed and mostly cacheable; trace LCP was 1.20 s in the unthrottled capture, though overall delivery issues are recorded under related checks. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | HAR recorded 60 requests and 3.27 MB transferred; Lighthouse estimated 277 KiB unused JavaScript and 62 KiB unused CSS, with four individual JS resources around 31–61% unused. CANVA-007 high: The anonymous homepage ships a large amount of avoidable code and network weight. |
be-inclusivenames-roles-labels | pass | medium | Lighthouse accessibility scored 100; button-name and link-name audits passed, and the template search input has an accessible label. |
be-inclusivesufficient-contrast | pass | medium | Lighthouse color-contrast passed and sampled screenshots remain legible. |
be-inclusivestructure-and-focus | pass | medium | Lighthouse heading-order passed; DOM contains header/nav/main/footer landmarks; focus probe found focus treatments. |
be-inclusivelegible-text | pass | medium | Desktop/mobile screenshots show large readable headings, comfortable body line-height and no clipped main copy outside the separately reported consent overlap. |
be-inclusivezoom-reflow-targets-and-media | pass | medium | Meta viewport allows scaling, Lighthouse target-size and viewport audits passed, and mobile layouts had no horizontal overflow. |
follow-best-practicesno-console-errors | pass | medium | Lighthouse errors-in-console audit passed with no logged console errors. |
follow-best-practicessound-document-and-assets | pass | medium | DOM has HTML5 doctype and UTF-8; Lighthouse image aspect-ratio and responsive-size audits passed. Unsized delivery is separately reported. |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse found an unload listener in sentry_browser.js and four BFCache failure reasons, including the unload handler and no-store responses. CANVA-009 medium: Deprecated unload handling prevents back/forward cache restoration. |
be-discoverabletitle-and-description | pass | medium | Home and templates expose descriptive rendered titles and meta descriptions; the template probe records “Free templates | Canva”. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Discoverability measured only 4% raw/rendered word coverage on home, 2% on templates and 4% on the presentation page; each was classified as a JS shell and raw HTML lacked title and h1. CANVA-011 high: Core public content is largely absent from raw server HTML. |
be-discoverablecanonical-and-indexing-signals | pass | medium | Rendered home has canonical URL and 107 hreflang entries; robots.txt allows core paths and declares two sitemap indexes; sampled pages returned HTTP 200. |
be-discoverablestructured-and-shareable-metadata | pass | medium | Home includes JSON-LD plus eight Open Graph tags and a canonical URL matching visible Canva organization/product content. |
be-private-and-securesecure-transport-and-headers | pass | medium | Page uses HTTPS with HSTS preload, nosniff, frame protection, strict-origin referrer policy and CSP; no client secrets were found. |
be-private-and-securedata-minimisation-and-third-parties | pass | medium | Consent offers reject/manage choices before optional analytics; tracker probe found one known error-monitoring origin and no third-party cookies. |
be-private-and-securein-context-permissions-and-modern-auth | pass | medium | No browser permission prompt appeared on load; login is user-initiated and Google identity is available. No inappropriate prompt was observed. |
be-private-and-securedefensive-browser-policies | issues | high | Headers inspection found CSP unsafe-eval and no Permissions-Policy. Cookie inspection found g_state without Secure and four of five cookies flagged, including SameSite=None cookies. CANVA-010 medium: Browser security policy and cookie posture have avoidable gaps. |
be-resilientprogressive-enhancement | issues | high | Raw HTML comparisons across three representative public templates retained only 2–4% of rendered words and omitted title/h1, despite the pages having substantial public content. CANVA-012 high: Public content and primary discovery journeys do not progressively enhance without JavaScript. |
be-resilientresilient-runtime-behaviour | pass | medium | Five representative routes loaded without clipped navigation or blank runtime states; the help route retained usable high-contrast chrome. |
be-resilientoffline-and-installable | not-applicable | high | Canva’s core editor is intrinsically online and collaborative; offline/installability was not treated as required for these public marketing surfaces. |
be-resilientnetwork-and-http-failure-states | pass | medium | The sampled invalid URL returned a branded roadblock with explicit home recovery rather than a blank shell. |
be-internationalisedlang-dir-and-logical-properties | pass | medium | Home reports lang=en-GB and dir=ltr, templates lang=en, 107 hreflang links, and rendered markup includes logical inline properties. |
be-internationalisedlocale-aware-data | not-applicable | high | The sampled public surfaces display no dates, currencies, durations or locale-sensitive numeric data requiring an Intl formatting judgment. |
be-internationalisedtime-zone-correctness | not-applicable | high | The sampled public surfaces contain no event scheduling or time-zone-sensitive values. |
be-trustworthyno-dark-patterns | pass | medium | Consent presents Accept, Reject and Manage as direct choices without confirmshaming; sampled pricing copy did not show disguised commitments. |
be-trustworthyhumane-error-handling | pass | medium | No required multi-field form was present on sampled public paths; template search is optional and does not produce premature validation. |
be-trustworthytrustworthy-input-assistance | pass | medium | The only sampled input is a labelled search field; autocomplete=off is appropriate for dynamic template-query suggestions. |
be-trustworthysafe-commercial-and-account-flows | pass | medium | Pricing and login entry points are clearly labelled; no forced continuity or hidden default was observed in the sampled anonymous states. |
be-sustainableoptimised-assets | issues | high | The image probe found all 13 images without width/height, 11 without srcset, 8 below-fold images not lazy-loaded and 9 legacy-format assets; Lighthouse independently failed the unsized-images audit. CANVA-008 medium: Homepage imagery is not delivered responsively or with stable intrinsic sizing. |
be-sustainableno-wasteful-work | pass | medium | Trace showed bounded TBT and trackers recorded only a small telemetry/error-monitoring request footprint before consent. |
be-sustainablethird-party-and-media-budget | pass | medium | No autoplay video/audio was present; transferred media was dominated by product imagery, though optimization issues are separately recorded. |
be-agent-readystructured-agent-capabilities | issues | medium | The platform probe found no WebMCP/model-context registration on the public product surface; agents must infer actions from a large rendered UI. CANVA-016 low: Canva’s agent-relevant productivity capabilities are not exposed as structured browser tools. |
be-agent-readyon-device-inference | not-applicable | high | The sampled public marketing and discovery surfaces expose no bounded inference task where built-in local inference is necessary to complete the user journey. |
be-memory-efficientno-leak-under-repeated-interaction | issues | medium | The baseline heap summary was 67.15 MB across 1.52M nodes; after 20 menu toggles it was 88.60 MB across 2.06M nodes, about 32% more bytes and 36% more nodes. Separate page sessions add variance, so this is a leak signal requiring allocation-retainer confirmation. CANVA-013 medium: Repeated navigation-menu toggling produced substantial retained-heap growth. |
be-memory-efficientbounded-footprint | issues | high | A post-load heap summary contained about 1.52M heap nodes, 8.77M edges and 67.15 MB self size before entering the editor. CANVA-014 medium: The initial memory footprint is disproportionate for a marketing landing page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | Neither heap summary listed Detached* constructors among the dominant retained constructors; the stronger growth signal is separately recorded. |
