Ghost Legs is a tool that matches subjects at the top to options at the bottom. Adding bridges between columns alters matching results.
Using HTML table, hosted on GitHub Page
It is fully supported. All clickable div in this page can be focused by Tab key, with Enter and Space keypress handled.
It is not supported. The main board is now hidden with aria-hidden attribute. Rendering with changing table cell border color is the key of this tool to show routes. Welcome to suggest me any improvement.
