在HTML中，如何用CSS画一棵圣诞树？请高手指教

圣诞树啊，应该是考虑怎样画三角形吧，用border就可以了哈。

html>


    
    
        .ss{
            height: 0;
            width: 0;
            position: absolute;
            border: 20px solid tan;
            border-color: transparent transparent #1fd224 transparent;
        }
        .s1{
            border-width:80px ;
            top: 100px;
            left: 400px;
         }
        .s2{
            border-width:100px ;
            top: 115px;
            left: 382px;
        }
        .s3{
            border-width:120px ;
            top: 126px;
            left: 362px;
        }
        .s4{
            border-width:140px ;
            top: 140px;
            left: 342px;
        }
        .dd{
            height: 130px;
            width: 40px;
            position: absolute;
            top: 420px;
            left: 460px;
            background-color: #1fd224;
        }
