CodeField

code-field

An editable, syntax-highlighted code textarea.

Forms with the wiring documented, not guessed. Form controls take labels, descriptions and error text through props, and their keyboard and screen-reader behavior is documented in the accessibility notes below — generated from the manifest, not hand-maintained. The repository’s behavior suite holds the underlying patterns on Chromium, WebKit and a Pixel 7.
