<p>These tests assert the behavior described at

</p>
<main>
<!-- Example 9
[T]he outer height of the inner box will exactly match the height of the outer box (200px), but its inner height will be 20px less, to account for its margins.
-->
<div style="height: 200px; border: solid;">
<div style="height: stretch; margin: 10px;" data-expected-height="180"></div>
</div>
<!-- Example 9, second case
In the following case, the height of the inner box will exactly match the height of the outer box (200px).
-->
<div style="height: 200px; margin: 0;">
<div style="height: stretch; margin: 10px;" data-expected-height="200"></div>
</div>
<!-- Example 10
Similarly, width: stretch causes the box to fill its container, being 20px narrower than the width of "some more text" (due to the 10px margin)
-->
<div style="float: left; margin: 0; outline: solid;">
<div style="width: stretch; margin: 10px; background: skyblue;"
data-expected-width="260">
text
</div>
<span>some more text</span>
</div>
<div style="clear: both;"></div>
<!-- Example 11
On the other hand, in this example the container’s height is indefinite, which would cause a percentage height on the child to behave as auto, so height: stretch behaves as auto as well.
-->
<div style="height: auto; margin: 0; background: orange;">
lorem ipsum<br>

<div style="height: stretch; margin: 10px; background: lime;"
data-expected-height="20">dogs</div>

document.fonts.ready.then(() => checkLayout("main > div > div"));
