| <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."> | |

| <!-- | |
| 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). | |
