Basically max-width, min-width, max-height and min-height are the properties of CSS 2 and are not supported by IE 6. It works well with IE 7 and mozilla firefox but not with IE 6 and lower versions of IE.
But i have found a solution for this and it goes as below:
eg: if you have one or more image to display such that there should be some restrictions of height and width of image. i.e. image should not be having width more than 500 (suppose) and height not more than 200, then the css for the image should be as given below:
width:expression(document.body.clientWidth > 500? “500px”: “auto” );
height:expression(document.body.clientHeight > 200? “200px”: “auto” );
same way you can try for min-width and min-height.
