HTML is parsed according to WHATWG HTML (the living standard), which is also followed by all browsers.
The syntax tree used is hast.
This package is fully typed with TypeScript.
Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line,
hast-util-is-css-link@^3
,
compatible with Node.js 16.
As rehype works on HTML and improper use of HTML can open you up to a
cross-site scripting (XSS) attack, use of rehype can also be unsafe.
Use rehype-sanitize
to make the tree safe.
