是否有可能使一個箱子箭頭CSS 3漸變

Question

如果你看一下下面的鏈接，你會看到一個飄綠盒子的箭頭指向左邊：

可這是隻使用CSS3完成？是否有可能使箭頭形狀和框中和箭頭都有梯度？如果是這樣，你會如何做到這一點？

感謝

Answer 1

這是最接近我可以用純CSS和HTML得到......唯一的問題是，不能使用漸變的箭頭提示。

<div class="arrow"></div><div class="content">Add new authorization</div> 

.arrow 
{ 
    width:2px; 
    height:2px; 
    border: 12px inset black; 
    border-right-width: 8px; 
    border-color: transparent #5a0 transparent transparent; 
} 
.content 
{ 
    background-color: green; 
    padding:2px 8px 2px 4px; 
    border: 1px solid #490; 
    border-left-width: 0px; 
    background-image: -webkit-linear-gradient(top, #8c0, #070); 
    text-shadow: 1px 1px #8c0, -1px -1px #070 
} 
div {float:left; color:white; 
}

在IE9和火狐，Chrome，Safari瀏覽器，歌劇的最新版本進行測試。
