我在 CodeIgniter 中有一个应用程序，我正在使用 twitter bootstrap，但我无法在 ie8 中获得圆角。
我试过 CSS3 pie 没有成功。我尝试将 .htc 文件放在不同的地方（appname/PIE.htc）并放置AddType text/x-component .htc，但也没有成功。
所以我现在尝试使用border-radius.htc。我的 CSS 和 ( border-radius.htc) 位于appname/application/views/resources/css/：
我的 css 文件如下所示：
@import url(bootstrap.css);
input[type="file"],
input[type="image"],
input,textarea,
input[type="file"]:focus,
input[type="radio"]:focus,
input[type="checkbox"]:focus,

behavior: url(border-radius.htc);
}
这在ie8中仍然不起作用。难道我做错了什么？
