<title>CSS Flexbox Test: Percentage size on child of a flex item with margin, border, padding and scrollbar</title>
<link rel="author" title="Manuel Rego Casasnovas" href="mailto:rego@igalia.com">
<link rel="match" href="reference/percentage-size-subitems-001-ref.html">
<meta name="assert" content="Checks that flex items children resolve properly their percentage sizes, even when the flex item has margin, border, padding and scrollbar.">
<style>
.flex {
display: inline-flex;
border: solid 5px black;
width: 150px;
height: 100px;
margin: 10px;
vertical-align: top;
}
.item {
flex: 1;
overflow: scroll;
border: solid magenta;
border-width: 12px 9px 6px 3px;
margin: 1px 2px 3px 4px;
padding: 5px 15px 10px 20px;
background: cyan;
}
.subitem {
width: 100%;
height: 100%;
background: yellow;
}
.horizontalTB { writing-mode: horizontal-tb; }
.verticalLR { writing-mode: vertical-lr; }
.verticalRL { writing-mode: vertical-rl; }
</style>
<p>The test passes if in the different examples you see scrollbars but there's no overflow, so you cannot actually scroll.</p>
