The code is as follows:

Copy code The code is as follows:

<!--[if IE 6 ]><script type="text/javascript">
try { document.execCommand('BackgroundImageCache', false, true); } catch(e) {}
</script>< ![endif]-->

Note: This BUG has been discovered before and is just mentioned again here.

For more detailed instructions, please refer to the following article:

Solve the problem of jitter during mouse operation when the image is used as the background in IE
Method 1, css (not recommended)

Copy code The code is as follows:

html {
filter: expression(document.execCommand("BackgroundImageCache", false, true));
}

Method 2, js
Copy content to clipboard

Copy code Code As follows:

try {
document.execCommand('BackgroundImageCache', false, true);
} catch(e) {}

In fact now Most of the solutions to the problem use CSS background positioning. That is, all the icons on the entire page are placed on one picture. (Take mail 163 as an example)
