How does CSS set the maximum width of all images in a div. When an image is added to an article, the image is automatically scaled down proportionally.

# A2 IMG {max-width: 100px; max-Height: 100px;} (IE7 or later, FF ..) IE6 is only implemented using Js. First, you must determine which value of the image's width and height is relatively large, and then determine whether the value is beyond the DIV's range. If the value is exceeded, if you do not want to use JS, you have to sacrifice IE6 Div {width: 20px; Height: 20px; Border: solid 1px # F11; overflow: hidden ;} div IMG {max-width: 20px; max-Height: 20px; _ width: 20px; _ Height: 20px;} (set the image to a fixed size in IE6, images of other browsers are automatically adjusted)
