another code to limit the maximum width and height of the picture, for reference only, in fact, the same homology with the aforementioned.
HTML code
Here is a combination of CSS and its supported expression implementations, the sample code is as follows:
<title> control the maximum height and width of the picture </title>
<style type= "Text/css" >
. Clear{clear:both;}
. widthimg{width:expression (This.width > 200?) ' 200px ': true); max-width:200px; }
</style>
<body>
<div class= "Clear" >
</div>
<div class= "Clear" >
</div>
</body>
<style type= "Text/css" >
<!--
img.pic{
max-width:300;
max-height:100px;
/* Because IE6.0 and previous versions of IE do not support the top two properties, the following two statements are added. Here to illustrate that expression is only IE support */
Width:expression (This.width > && this.width/300 >= this.height/100? 300:true);
Height:expression (This.height > && this.width/300 < this.height/100 100:true);
}
-
</style>
<body>
<div id= "pic" >
</div>
</body>
Because the top of the code, set the maximum length of the width is directly with the number, and then modify the time is very inconvenient, so made the following changes:
<script type= "Text/javascript" >
<!--
Object.max_width = 400;
Object.max_height = 300;
-
</script>
<style type= "Text/css" >
<!--
img.pic{
max-width:300px;
max-height:100px;
Width:expression (This.width > Object.max_width && this.width/object.max_width >= this.height/object.ma X_height? Object.MAX_WIDTH:true);
Height:expression (This.height > Object.max_height && this.width/object.max_width < This.height/object. Max_height? Object.MAX_HEIGHT:true);
}
-
</style>
<body>
<div id= "pic" >
</div>
</body>
In this case, you only need to modify the Object.max_width and object.max_height the two class variables can easily modify the maximum length and width.
Set Web page minimum maximum width and height (compatible with IE6)
