邊界圖像圓角

Question

我有一個使用線性漸變爲邊界的圖像給它一些漸變邊框

<div class = "gradborders" id="mydiv" runat="server"> 
..various elements... 
</div> 
.... 
.... 
.gradborders{ 
border-image: -webkit-linear-gradient(45deg, rgba(20,20,20,0.7) 5%, rgba(90,90,90,0.5) 35%, rgba(255,255,255,0.2) 100%) 8 stretch; 
border-image: -o-linear-gradient(45deg, rgba(20,20,20,0.7) 5%, rgba(90,90,90,0.5) 35%, rgba(255,255,255,0.2) 100%) 8 stretch; 
border-image: -moz-linear-gradient(45deg, rgba(20,20,20,0.7) 5%, rgba(90,90,90,0.5) 35%, rgba(255,255,255,0.2) 100%) 8 stretch; 
border-image: linear-gradient(45deg, rgba(20,20,20,0.7) 5%, rgba(90,90,90,0.5) 35%, rgba(255,255,255,0.2) 100%) 8 stretch;} 

一個div，我想圓潤邊角。我試圖通過將這種標準方式添加到越南境內：

border-radius: 8px; 
-webkit-border-radius: 8px; 
-moz-border-radius: 8px; 

但沒有骰子。我甚至嘗試在div上使用AJAX Rounded Corner擴展器，我確信它可以正常工作，但這也不起作用。有任何想法嗎？？

Answer 1

也許這樣的事情JSFiddle會做：

<div class="container"> 
    <div class="gradborders">hi</div> 
</div> 

和

.container{border-radius: 10px;overflow:hidden;} 
.gradborders{ 
-webkit-border-image: url("http://photos-f.ak.fbcdn.net/hphotos-ak-ash4/1686_520555094669668_1347475803_n.jpg") 8;}
