刪除標題欄周圍的邊框

Question

好吧，我把這個淺灰色的顯示靠近了標題欄「獨立新聞」中的曲線。它實際上顯示的背景不是一個邊框。

我有這個作爲我的HTML，我認爲它有一個表的表內造成的？但不確定。

<div id="contentwrapper"> 
    <!-- NEWS START --> 
    <table width="100%"><tr><td> 
     <div class="rounded"> 
      <div class="rounded_top"> 
       <div>Indie News</div> 
      </div> 
      <div class="rounded_content"> 
       <font align='Right'><a href="#" >Submit Your Story</a> </font>   
      </div> 
      <div class="rounded_bottom"> 
      </div> 
     </div> <!-- end of rounded--> 
     <table><tr><td align='center'> 
      <div id='coin-slider'> 
       <a href="images/newsimage/minecraft1.jpg" target="_blank">

     </tr> 
     <tr>

     </tr> 
     <tr> 
      <td>Now here's a surprisingly nice piece of news. Stealthy demolition game Dynamite Jack has already been a reasonable .</td> 
     </tr> 
     <tr> 
      <td bgcolor='#7e7e7e'><a href="#" > 0 comments</a> | <a href="#" >Leave a comment</a> </td> 
     </tr> 
    </table><!--end of review table--> 

</div><!--end of contenet wrapper-->

border: None; 

}

.rounded_top div, .rounded_top, 
.rounded_bottom div, .rounded_bottom {

.rounded_content { margin: 0 20 0 20;} 
.rounded { color:#000000;}

它通常是建立一個網站時，瀏覽器確保之間的兼容性重置樣式是一個好主意。風格會去是這樣的：

*{ 
margin:0; 
padding:0; 
border:0; 
}

嗨現在定義#contentwrapper, .roundedborder raius

#contentwrapper, .rounded{ 
border-radius:20px 20px 0 0; 
-webkit-border-radius:20px 20px 0 0; 
-moz-border-radius:20px 20px 0 0; 
}
