MDX allows for certain things beyond what markdown is capable of. Content here will discuss using those features to augment or modify the default content layout.

Frontmatter

You can declare frontmatter in your .mdx files to provide specific metadata for the theme to use.

  • title: Main page title: search results and SEO
  • description: SEO and search results
  • keywords: just SEO (optional)
  • hiddenFromSearch: if true, page will be excluded from search

keywords: 'ibm,carbon,gatsby,mdx,markdown'
hiddenFromSearch: true

Smart quotes

The theme has a remark for processing straight quotes, into ‘smart’ quotes (”). However, this plugin isn’t able to process text used in custom MDX components. When using quotes in custom components, content authors should manually use “smart quotes” to adhere to the IBM Design Language content guidelines.

Custom title

You can export a Title component in order to render a unique title for a single page. This is particularly useful for including line breaks at a specific location.

Note: You still need to provide a regular string title to the frontmatter for search, navigation, and the HTML header title to work.
