如何仅使用CSS在iPhone经典样式中设置聊天气泡样式

Question

我试图创建一个类似于Messages（thread view）的html页面，就像在我们的android和iphone设备中一样。

这是我编码的

CSS样式：

<style type='text/css'>
.triangle-right 
 {  
        position:relative;   
        padding:15px;   
        color:#fff;   
        background:#075698;   
        background:-webkit-gradient(linear, 0 0, 0 100%, from(#2e88c4), to(#075698));   background:-moz-linear-gradient(#2e88c4, #075698);   
        background:-o-linear-gradient(#2e88c4, #075698);   
        background:linear-gradient(#2e88c4, #075698);   
        -webkit-border-radius:10px;   
        -moz-border-radius:10px;   
        border-radius:10px;   
 }   
 .triangle-right.top   
 {     
    background:-webkit-gradient(linear, 0 0, 0 100%, from(#075698), to(#2e88c4));   
    background:-moz-linear-gradient(#075698, #2e88c4);   
    background:-o-linear-gradient(#075698, #2e88c4);   
    background:linear-gradient(#075698, #2e88c4);   
 }   
 .triangle-right.left   
     {   
            margin-left:10px;background:#075698;   
     }   
     .triangle-right.right   
     {   
        margin-right:10px;  background:#075698;   
     }   
     .triangle-right:after    
     {   
     content:'';   
         position:absolute;   
         bottom:-20px;left:50px;border-width:20px 0 0 20px;border-style:solid;border-color:#075698 transparent; display:block;width:0;   
     }   
     .triangle-right.top:after    
     {   
        top:-20px;right:50px;bottom:auto;left:auto;border-width:20px 20px 0 0;border-color:transparent #075698;    
     }   
 .triangle-right.left:after    
     {   
        top:16px;left:-15px;    bottom:auto;border-width:0 15px 15px 0;border-color:transparent #E8E177;   
     }   
     .triangle-right.right:after   
     {   
        top:16px;right:-15px;bottom:auto;left:auto;border-width:0 0 15px 15px; border-color:transparent #8EC3E2 ;   
 }  
.triangle 
{
width: 0;
height: 0;
    border-left: 50px solid transparent;
    border-right: 100px solid transparent;
    border-bottom: 50px solid #fc2e5a;
}

我尝试更改一些值

     .triangle-right.left:after    
     {   
        top:16px;left:-15px;    bottom:auto;border-width:0 15px 15px 0;border-color:transparent #E8E177;   
     }   
     .triangle-right.right:after   
     {   
        top:16px;right:-15px;bottom:auto;left:auto;border-width:0 0 15px 15px; border-color:transparent #8EC3E2 ;   
 } 

但无法获得所需的确切形状。我需要以以下方式构造泡沫
