The code tabs rendered by the example viewer (e.g. the npm/pnpm/yarn/bun
install tabs) paint their active label as transparent text clipped to a
gradient. Material's MDC tab styles add `transition: color 0.15s linear`
to `.mdc-tab__text-label`, plus a 100ms delay on the active tab. Because
that transition animates `color` from the solid label color to
transparent, the solid color stays visible on top of the gradient for
~100ms when a tab is activated, which reads as a white flash.
Disable the transition on these labels so the color switches instantly,
and target `.mdc-tab__text-label` directly (instead of a generic `span`)
so `color: transparent` drives the gradient clip cleanly.
When a documentation table has a wide content column, the narrow header
columns get squeezed and inline-code header labels break mid-word at
their hyphens. On the MCP server tools page this rendered the `local-only`
and `read-only` column headers as `local-` / `only` and `read-` / `only`.
Apply `white-space: nowrap` to `code` inside `th` so header tokens stay on
a single line. The rule is scoped to headers, whose labels are always
short, so long code signatures in body cells continue to wrap and no
table gains a horizontal scrollbar.
Follow-up to #69205. After switching adev's COEP to `credentialless`, the
cross-origin YouTube iframe in `<docs-video>` loads in Chromium and Safari but
not Firefox, whose `credentialless` policy does not extend to nested frames. The
result was a COEP error screen instead of the player.
Render `<docs-video>` as a lightweight thumbnail facade instead of embedding the
iframe directly. The thumbnail is a cross-origin subresource, so it loads under
`credentialless` in every browser. `DocViewer` then upgrades the facade to the
inline player on hydration in browsers that can load the embed (Chromium,
Safari), preserving the previous behavior there. On Firefox the facade stays a
plain link that opens the video on YouTube (with autoplay), which replaces the
error screen.
The thumbnail uses `maxresdefault` and falls back to `hqdefault` when a video
has no max-resolution image.
Add font family, size and weight to the `.docs-primary-btn`. This guarantees that applying the class to non-button elements, like anchors, will results in the same visual representation.
#68940 introduced a regression that broke style for wrapped `code` blocks.
Simplifying the style by droping the unecessary gradient + before workaround fixes the issue.
Uses 1px increments for media queries, rather than the 0.01px we have now which seem to be a bit too precise and cause the UI to be stuck between states in some cases.
I've also removed some unnecessary `calc`, because the calculation is happening inside Sass already.
Fixes#69020.
Updates the Playground card copy and adds a `titleInline` attribute on
<docs-card> so the icon and title sit on the same row. Existing cards
are unaffected.
Inline code elements inside table cells inherited `width: 100%` from
the global code styles, causing short codes like `s`, `dev` to stack
vertically instead of rendering on the same line. Add `min-width` to
table cells containing code to ensure proper inline layout.
Replaced padding-block-start with margin-block-start on
.docs-reference-section-heading to prevent anchor hover and click areas from extending into empty space above the heading. This ensures hover behavior aligns with the visible text.
The .docs-primary-btn hover state in dark mode had a contrast ratio of 2.18:1,
failing WCAG 2.1 SC 1.4.3. This change reuses the existing
--hot-pink-to-electric-violet-radial-gradient to achieve 4.5:1+ contrast.
Add CSS rule to hide the last empty line in code blocks to prevent displaying
unnecessary empty lines when source files end with a newline character.
The empty line remains in the DOM for proper copy-paste functionality.
This change fixes an issue where long lists of enum values would display on a single line, running off the screen, especially on mobile devices.
