Children of the Canvas
Can I make a canvas accessible with its fallback DOM? Does it get positioned properly?
by David Iglesias
HTML
<canvas id="drawing" width=640 height=480></canvas>
CSS
canvas {
position: relative;
}
canvas * {
position: absolute;
}
JavaScript
const ctx = drawing.getContext("2d");
ctx.fillRect(25, 25, 100, 100);
ctx.clearRect(45, 45, 60, 60);
ctx.strokeRect(50, 50, 50, 50);
// Add accessibility child into canvas, matching the stroke rect
let link = document.createElement('a');
link.style.width = "50px";
link.style.height = "50px";
link.style.top = "50px";
link.style.left = "50px";
link.href = "https://www.google.com";
link.innerText = "Google!";
link.target = "_blank";
drawing.appendChild(link);
