While working on my blog I discovered that some of the image and link sources in different posts had become broken without me noticing. Outside of “hugo says OK” I don’t have any other validation running on my blog so I decided to look for something that could lint the rendered output for dead links and other issues. I tried a number of different tools but ended up using htmltest. It runs after hugo renders the static output of my blog in a public/ directory in the project root.

Web content accessibility has been on my mind recently as I watched one of the other engineering teams at Intercom in San Francisco undertake to make the Intercom Messenger accessible and compliant with the Web Content Accessiblity Guidelines (WCAG) 2.0 Level AA. Despite the continued growth and evolution of the internet it has yet to really live up to its true potential as universally accessible communication, and the accessibility landscape of online content is no exception.
