Stretching of background images in HTML

The HTML background is sometimes changed because of the browser size (this "change" is repeat). How to stretch it? I 've been checking it online for a long time, I found a good thing called "filter", and the effect was achieved-the background was scaled with the browser size, but the links on the page were all invalid. I don't know why, so I should put it here first, after all, only ie5.5 + can be used, and later I understand the continued writing.

Filter: progid: DXImageTransform. Microsoft. alphaimageloader (Enabled =Benabled, Sizingmethod =Ssize, Src =Surl),

Attribute:

Enabled	:	Optional. Boolean ). Set or retrieve whether the filter is activated.True|False True : Default Value. Filter activation. False : The filter is disabled.
Sizingmethod	:	Optional. String ). Sets or retrieves the display mode of the image of the object to which the filter applies within the boundary of the object container. Crop : Cut the image to fit the object size. Image : Default Value. Increase or decrease the size boundary of an object to fit the image size. Scale : Scale the image to adapt to the size boundary of the object.
SRC	:	Required. String ). Use absolute or relativeURLThe address specifies the background image. If this parameter is ignored, the filter will not work.

Features:

Enabled	:	Read/write. Boolean ). SeeEnabledAttribute.
Sizingmethod	:	Read/write. String ). SeeSizingmethodAttribute.
SRC	:	Read/write. String ). SeeSRCAttribute.

Note: An image is displayed between the background and content of the object within the boundary of the object container. You can also cut and change the size of the image. If the file is loaded in PNG (Portable Network Graphics) format, the transparency between 0% and 100% is also provided.
The transparency of images in PNG (Portable Network Graphics) format does not affect your choice of text. That is to say, you can choose to display the content after the completely transparent area of images in PNG (Portable Network Graphics) format. Example: # iddiv {position: absolute; left: 140px; Height: 400; width: 400; filter: progid: dximagetransform.microsoft.alphaimageloader(src='rain1977.gif ', sizingmethod = 'Scale ');}
. Dream {filter: progid: DXImageTransform. Microsoft. alphaimageloader (src = 'images/earglobe.gif ');} msdn: http://msdn2.microsoft.com/en-us/library/ms532969.aspx

P.s. When you want to use the backgroundimage attribute, You can implement this filter if you do not want to display the original image size, but like IMG width = 100% heigth = 100%.

Example:
Span. style. Filter = "progid: dximagetransform.microsoft.alphaimageloader(src='test.jpg ', sizingmethod = 'Scale ')";

Reference: Finally, let's talk about the effect reconciliation between FF and IE. This filter effect is only applicable to IE and cannot be displayed under ff. I think this is the final problem that the predecessor said he was hard to implement. In the past, we used * or _ to fix the difference between IE and ff. This time we were looking for a way to fix the problem that FF could not be implemented.
In fact, it is easy to think. let FF display the image normally first, then use * or _ to clear the display effect under IE, and finally use * or _ to do the above filter effect. Success!
