| <meta name="assert" content="The 'height' is the distance between the top border edge of the top most block-level child box that doesn't have margins collapsed through it, and the bottom border edge of the bottommost block-level child that doesn't have margins collapsed through it. When a block-level non-replaced element is in normal flow, 'overflow' computes to 'visible' and the 'height' is 'auto'."> |
