+<meta name=assert content="Layout containment does apply to buttons, thus their baseline is their margin-bottom edge.">
+<style>
+button {
+ border: 5px solid green;
+ padding: 0;
+ /* We use a nonzero margin-bottom to be sure we're synthesizing a baseline
+ from the margin-box rather than from the border-box: */
+ margin-bottom: 2px;

+ color: transparent;

+ height: 0;
+}
+</style>

+<p>This test passes if it has the same output as the reference. You see the word "before", a 10px green square aligned 2px above the text's baseline, and then the word "after".</p>
