If you only need to be compatible with IE6, you do not need to pay attention to the Min-height style, because IE6 does not support this style at all. However, when you need to take care of IE7 and FF, you must pay attention to this style. Because many styles with a fixed value of Height = are configured in IE6, IE7 and FF do not adapt to the height when the container is held above the height. This leads to layout confusion. To adapt the height to IE6, IE7, and FF, set Min-height and csshack. For example:
Min-Height: 600px;
_ Height: 600px;
In this way, when there are few items in the container, it shows a fixed height of PX, but when there are many items in it, it will also automatically increase the height.
Pay special attention to the height setting. If it is the height of the container used for layout, pay special attention to it. Otherwise, it will not float in ff, this makes layout messy # html/XHTML/XML Columns
