正しいメッセージを表示するために使用されるクラスがあります。このクラスは、Internet Explorer 8でエラーが見つかったことを除いて、すべてのブラウザーでうまく機能します。
.success{
border:#060 1px solid;
margin-left:25%;
margin-right:25%;
padding:7px;
background-color:#D9FF80;
background-image:url(http://localhost/naju/home/css/css_img/ok.png);
background-position:left;
background-repeat:no-repeat;
padding-left:30px;
font-family:"Trebuchet MS", Arial, Helvetica, sans-serif;
font-size:13px;
color:#003300;
font-weight:bold;
-moz-border-radius:5px 5px 5px 5px;
-moz-box-shadow:0 5px 3px #DDDDDD;
-webkit-border-radius:5px 5px 5px 5px;
behavior: url(border-radius.htc);
}
上で示したように、クラスには外部動作（border-radius.HTC）が含まれています。これは、InternetExplorerでも丸みを帯びた境界線を示しています。しかし、私の問題は、私がラインを維持する場合：
behavior: url(border-radius.htc);
InternetExplorerはバックグラウンドリピートを表示します。しかし、上記では、バックグラウンドリピートを設定しました：no-repeat。振る舞いを削除すれば問題ありません。ただし、この問題はInternetExplorerでのみ発生します。なぜそうなるのかわかりません...InternetExplorerで予期しない背景の繰り返しを止める方法は？plz何か助けがありますか？
HTCファイルの内容は以下のとおりです。

Changes by Nick Fetchak:
- IE8 standards mode compatibility
- VML elements now positioned behind original box rather than inside of it - should be less prone to breakage
