Serious Level A WCAG 2.1.1 — Keyboard

What’s wrong

An <img ismap> sends click coordinates to the server to determine where the user meant to go. This only works with a mouse, there’s no way to trigger it from a keyboard.

Why it matters

Coordinate-based navigation has no keyboard equivalent by definition. Anyone who can’t click a specific pixel is completely locked out of that navigation.

How to fix it

Replace it with a client-side image map (<map> + <area> with real href targets) or a set of regular links.

Before
<a href="/map-handler"><img src="/campus-map.png" ismap></a>
After
<img src="/campus-map.png" usemap="#campus">
<map name="campus">
  <area shape="rect" coords="0,0,100,100" href="/library" alt="Library">
</map>
