<meta name="assert" content="This test checks how 'min-height' with calc(percentage) and 'box-sizing' are handled. The percentage in the calc() is calculated on the content box height of div#container.">
<style>
div#container
{
border-bottom: transparent solid 100px;
border-right: transparent solid 100px;
height: 400px;
width: 100px;
}
div#item
{
background-color: red;
box-sizing: border-box;
height: 50px;
min-height: calc(50% - 100px);
}
div#item > div
{
background-color: green;
border-bottom: green solid 34px; /* arbitrary border-bottom-width value */
border-top: green solid 12px; /* arbitrary border-top-width value */
box-sizing: border-box;
height: 17px;
min-height: 100%; /* content height should be 100px - 34px - 12px == 54px */
overflow-y: visible;
/*
If the content height of innermost div is taller
than 54px, then a green rectangle (not a square)
will be created.
If the content height of innermost div is less
than 54px, then an horizontal stripe of red
will become visible.
*/
}
</style>
<p>Test passes if there is a filled green square and <strong>no red</strong>.
