<link rel="help" href="https://drafts.csswg.org/css-ui-3/#resize">
<meta name="flags" content="interact may">
<meta name="assert" content="UAs may apply the resize property to <canvas> regardless of the value of the overflow property.">
<style>
canvas { resize: both; }
</style>

<p>Test passes if both <strong>width</strong> and <strong>height</strong> of the orange box below can be adjusted (for instance by dragging the bottom-right corner).</p>

<canvas id="test" width="100" height="100">
  &lt;canvas&gt; is not supported. This test is non conclusive.
</canvas>
<script>
var canvas = document.getElementById('test');
if (canvas.getContext) {
  var ctx = canvas.getContext('2d');
    ctx.fillStyle = '#FFA500';
    ctx.fillRect (0, 0, 100, 100);
}
