Problem - The test mentions "... there should be no red below, just a block of green."
When opened in any standards compliant browser, it does show the red image. After referring to http://www.w3.org/TR/CSS21/colors.html#propdef-background
, and analyzing the code on the test case, according to my understanding the red background should be visible just as it is. So is this a case of overlooked copy or am I missing something ?
