ie-css3.htc放在服务器上，也可以正常访问，为什么在IE8上看不到效果呢，百思不得其解呀，你们觉得是什么问题呢？

Personal testing is OK. Just put it in the root directory and take a look

Haha, I guessed it, cross-domain is not supported.
If is placed in the root directory of the website and accessed as http://127.0.0.1/index.html, the CSS file cannot write behavior: url(http://localhost/ie-css3.htc); instead write behavior: url(http://127.0.0.1/ie-css3.htc);. However, it is best to use relative paths if the css file is in the same directory as ie-css3.htc. In the same folder, write behavior: url(ie-css3.htc);
Test environment: windows7 + IE8
Also:
The current element must have positioning attributes, such as position:relative or position:absolute attributes.
z-indexThe value must be higher than the surrounding elements
border-radiusSetting only one corner is invalid
box-shadow can only be set to #000
text-shadowThe performance under IE is slightly different from Firefox/Safari/Chrome, the reason is unknown
Reference: Let IE6/IE7/IE8 browser support CSS3 attributes
