Ensures the example viewer header displays correctly by keeping the "Show code"
button aligned to the right and preventing metadata text from wrapping.
Improves layout consistency across documentation examples.
Rather than using multiple view modes for code examples, we can just treat the previous snippet mode as
as multifile mode that just only has one file in it.
- Replaced <a><button></button></a> with a proper <a> containing text and
aria-label to ensure links have discernible text.
- Added main tag in home page to provide
a consistent main landmark, improving accessibility for screen readers
and satisfying WCAG and Lighthouse requirements.
Fixes#65181.
The example viewer has some `::ng-deep` styles that are used to reset global styles that leak into the live examples. It works by applying a style like `.docs-example-viewer-preview * {all: revert;}`.
The problem with this is that depending on when the first example is rendered, the styles will be lower or higher in the cascade, thus making the reset unreliable. Furthermore, it can affect structural styles from the CDK which intentionally have low specificity.
These changes move the resets into the global stylesheet to make them more predictable.
Long code blocks overflow the headings on narrow screen (like mobiles), this messes up the global layout of the page. With the ellipsis with fix that.
fixes#64845
The DocViewer component's getCodeSnippetsFromMultifileWrapper method was not
extracting the header attribute from nested <docs-code> elements, causing the
ExampleViewer to fall back to displaying file paths instead of custom headers
in tab labels.
This change adds title extraction from the header attribute when processing
multifile code snippets, ensuring that custom headers are properly displayed
in the code viewer tabs.
Fixes#64760
The navigation list component was using `routerLinkActive` with
`{ exact: true }`, which required an exact URL match including query
parameters. When visiting `/update-guide?v=19.0-20.0&l=1`, the link
`/update-guide` didn't match, so the active class wasn't applied.
Updated `routerLinkActiveOptions` to ignore query parameters while
maintaining exact path matching so the navigation item stays highlighted
when interacting with the update guide form.
The ExampleViewer component was extracting only innerHTML from code
blocks in multifile examples, which lost the shell class applied by
the formatCode function. This caused the $ prompt to not appear for
shell commands in multifile blocks even when language="shell" was set.
Modified the Snippet interface to track shell language state and
updated getCodeSnippetsFromMultifileWrapper and getStandaloneCodeSnippet
methods to preserve the shell class. Updated example-viewer template
to conditionally apply the shell class to the code wrapper element.
Fixes inconsistency between standalone and multifile shell code blocks.
Ensures that file names remain visible even if the associated code block
is collapsed or hidden, improving readability and context in the docs.

This fix updates the adev `DocViewer` component to support rendering with the `main[docsViewer` selector so that the primary content for the page is inside of a `<main>` element (without introducing an extra DOM element).
