是否可以在背景中制作带箭头和渐变的圆圈？

Question

我需要在里面做一个带箭头和渐变的圆圈.我知道我可以用它作为图像.但它需要灵活调整屏幕大小,以便背景渐变动态变化.我很好奇是否可以使用单个<span>标签和CSS 来做到这一点.

下面是一个使用两个div来使用rotation和border-radius模拟箭头的示例:

  .btn{
    cursor:pointer;
    position:relative;
    font-family:'Trebuchet MS', Verdana, Arial, sans-serif;
    display:inline-block;
    padding:3px 0 3px 16px;
    text-align:center;
    height:22px;
    color:#696969;/*#DB7DB4;*/
    text-shadow:0px 1px 1px #fff;
    -webkit-border-radius: 22px;
    -moz-border-radius: 22px;
    border-radius: 22px;
    border:1px solid rgba(220,87,166,0.8);
    box-shadow: 0px 0px 0px 3px rgba(220,87,166, 0.8);

    background: #fafafa; /* Old browsers */
    background: -moz-linear-gradient(top,  #fafafa 0%, #939393 100%); /* FF3.6+ */
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#fafafa), color-stop(100%,#939393)); /* Chrome,Safari4+ */

    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#fafafa', endColorstr='#939393',GradientType=0 ); /* IE6-9 */  
  }

  .btn_circle{
    position:relative;
    float:right;
    margin:0px 3px 0 8px;
    display:table;
    width:20px;
    height:21px;
    border:1px solid rgba(255,255,255,0.6);
    border-radius:21px;
    box-shadow: inset 0px 3px 2px rgb(92, 38, 70);

    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#6b294f', endColorstr='#aa6592',GradientType=0 ); /* IE6-9 */
  }

  .btn_arr{
    position:absolute;
    right:8px;
    height:3px;
    width:10px;
    background:#d9d9d9;
    -webkit-border-radius: 3px;
    -moz-border-radius: 3px;
    border-radius: 3px;
    box-shadow:-1px 0px 1px #6F375D;
  }
  .btn_top{
    top:11px;
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    transform: rotate(45deg);
  }
  .btn_bot{
    top:16px;
    -webkit-transform: rotate(-45deg);
    -moz-transform: rotate(-45deg);
    transform: rotate(-45deg);
  }
