Scale the image proportionally with CSS

Scale down or enlarge a large image to a certain size. For standard browsers (such as Firefox) or the latest IE7 browser, use Max-width and max-height directly; or the CSS attribute of Min-width and Min-height. For example, IMG {max-width: 100px; max-Height: 100px;} IMG {Min-width: 100px; Min-Height: 100px;} for browsers in IE6 and earlier versions, the supported expression attributes can be used to embed Javascript code in CSS code to scale the image. thumbimage {max-width: 100px; max-Height: 100px;}/* for firefox & IE7 */* HTML. thumbimage {/* For IE6 */width: expression (this. width & gt; 100 & this. width> This. height? 100: auto); Height: expression (this. Height> 100? 100: auto);} due to the image enlargement, there may be image aliasing problems, which are generally used to reduce the image.
