min-width:785px; width:expression(document.body.clientWidth < 800 ? "785px" : "100%" );
box { min-height:100px; /*高度最小值设置为:100px*/ height:auto !important; /*兼容FF,IE7也支持 !important标签*/ height:100px; /*兼容ie6*/ overflow:visible; }
#mycss { width:100%; max-width:500px; width:e?xpression_r_r_r(document.body.clientWidth > 500? "500px": "auto" ); } 或是: #mycss { max-width: 33em; width: expression_r_r_r(document.body.clientWidth > (500/12) * parseInt(document.body.currentStyle.fontSize) ? "33em" : "auto" ); }
#mycss { min-width: 333px; width: expression_r_r_r( document.body.clientWidth < 334 ? "333px" : "auto" ); }
#mycss { max-height: 333px; height: e?xpression_r_r_r( this.scrollHeight > 332 ? "333px" : "auto" ) }
#mycss { min-height: 333px; height: e?xpression_r_r_r( this.scrollHeight < 334 ? "333px" : "auto" ); }另外还有一种简单的方法:
#a {height:auto !important; min-height:400px;}
