Head Metadatas

Docusaurus automatically sets useful page metadatas in <html>, <head> and <body> for you.

It is possible to add extra metadatas (or override existing ones) by using the <head> tag in Markdown files:

markdown-features-head-metadatas.mdx

---id: head-metadatastitle: Head Metadatas---
<head>  <html className="some-extra-html-class" />  <body className="other-extra-body-class" />  <title>Head Metadatas customized title!</title>  <meta charSet="utf-8" />  <meta name="twitter:card" content="summary" />  <link rel="canonical" href="https://docusaurus.io/docs/markdown-features/head-metadatas" /></head>
