Assertion:
Note: There is only one CSS property that I think can have any effect on this element: the 'display' property. Setting the value to 'none' will make the line break disappear. Otherwise, this is a 'Replaced Element' that is replaced in the document with a line break and thus has no intrinsic display properties.
