ARIA Grid: Supporting nonvisual layout and keyboard traversal

What this post added

This post introduces the concept of a 'logical grid' and its implementation using ARIA Grid semantics to improve keyboard navigation and non-visual layout support in complex web applications. It addresses the challenge of numerous tab stops by consolidating them into a single tab stop within a grid, allowing for arrow key traversal. The post details the application of this pattern to a to-do list, explains the ARIA Grid roles, and provides a React.js implementation example, highlighting challenges like focus management and gaps in the grid.
