<meta content="This test checks that a line box height does not increase because an inline non-replaced box has a border. In this test, the '34' inline box and the '56' inline box should be lined up with its inline '12' sibling. The line box height, enclosed by the blue border should not grow to accommodate transparent 'border-left' of inline box and transparent 'border-right' of inline box." name="assert" />
