Build with a more recent version of pandoc ( > 2.11 )

The version of pandoc being used by the CI to build the site, has a quite annoying accessibility issue surrounding code-blocks.

Every line in a codeblock has an <a> tags with aria-hidden="true" on it, linking to an id element which is accessible via tab navigation through the site, causing anyone using that style of navigation to have to press tab to navigate past a hidden element for each line of code in any given example. further reading on the issue

This an example of the offending HTML from the website produced by pandoc 2.9.2.1 in your CI image

This issue has been fixed by later versions of pandoc by including the tabindex="-1" attribute on these a tags. I believe the fix lands in pandoc 2.11. pandoc release notes for 2.11 The fix is updating the skylight engine, where the actual fix occurred in their version 0.10. skylighting 0.10 changelog

This is what pandoc 2.17.1.1 produced for me when building it locally. image
