<title>CSS Pseudo-Elements Test: inheritance of selection highlight background color from its parent element</title>
<link rel="author" title="Gérard Talbot" href="http://www.gtalbot.org/BrowserBugsSection/css21testsuite/">
<link rel="match" href="cascade-highlight-005-ref.html">
<meta name="assert" content="In this test, 'background-color' has not been specified a value for the highlight pseudo-element of the span element. Since the span's parent element has an highlight pseudo-element also, then the span's background color for its highlight pseudo-element should be inherited from its parent highlight pseudo-element. Therefore the span element should have a green background color.">
<!--
This is a modified version of Example 11
found in § 3.5 Cascading and Per-Element Highlight Styles
-->
<!--
When any supported property is not given a value by the
cascade, its value is determined by inheritance from the
corresponding highlight pseudo-element of its originating
element's parent element (regardless of whether that property
is an inherited property).
