"This property specifies whether a box should float to the left, right, or not at all. It may be set for elements that generate boxes that are not absolutely positioned. The values of this property have the following meanings:
left The element generates a block box that is floated to the left. Content flows on the right side of the box, starting at the top (subject to the 'clear' property). The 'display' is ignored, unless it has the value 'none'.
right Same as 'left', but content flows on the left side of the box, starting at the top.
none The box is not floated. "
这说明浮动元素上的{display: inline;}会被忽略,事实上所有的浏览器没有呈现任何改变,包括IE。但是,它不知何故让IE停止将浮动元素的边界翻倍。因而,这个修复办法可以被直接应用,而没有任何繁琐的隐藏方法。如果将来的一款浏览器决定对这个修复办法抱恙,只要把这个修复装入IE独用的Tan Hack里,细节如同IE Three Pixel Text-Jog Demo。
