CSS技能：运用DIV标签规划最小高度及自在扩展高度_html/css_WEB-ITnose

发现需求类似td中height特点既能够确保最小高度又能够完成自在扩展高度的办法。逐步用div规划替换tabl规划的过程中。

通过查找资料和试验。可是该办法在ie6下不支撑，发现min-height能够完成最小高度。所以在款式中添加_height特点，此外关于可变高度的div假如需求自在扩展则不运用height特点即可，假如采用了height则div中的内容太长会跨过下鸿沟。

上下摆放的div1和div2假如div1高度添加后。此刻需求添加clear:both特点即可完成div2随着div1高度改变而移动top方位FireFox中div2会叠在div1后边。

div{clear:both;min-height:100px;_height:100px;}可完成最小高度、对于可变高度的div完成自在扩展高度并对于IE6IE7FireFox兼容。
