.minh1000{min-height:1000px; height:expression(this.clientHeight < 1000 ? "1000px" : (this.style.height.trim() == "auto" ? "auto" : this.style.height));}

.maxw1000{max-width: 1000px;  width:expression(this.clientWidth  > 1000 ? "1000px" : (this.style.width.trim()  == "auto" ? "auto" : this.style.width));}
