如何在输入字段上方放置一个加号

How to place a plus symbol over top of a input field

The current output of my pgm(the red nd green circle were edited by me for ur understanding) 红色圆圈内的加号应该在绿色圆圈的位置。

你能帮我解决这个问题吗..!! 提前致谢,

我的代码:

 .plussymbol{
     font-size: 40px;
     color: #a4508b;
     background-color:transparent;
     border-radius: 20px;
     border: none;
     display: inline-block;
     cursor: pointer;
     position: absolute;
    /*top: 37%;
     right: 28%;
    */
     padding-top: 15px;
     vertical-align: middle;
}
 .userip{
     width:90%;
     height: 65px;
     border-radius: 30px;
     font-size: 27px;
     font-weight: lighter;
     font-family: 'Hanalei Fill', cursive;
     background-color: #ece7e7;
     color: #000;
     border: none;
     -webkit-box-shadow: 0px 10px 20px rgba(0, 0, 0, 0.6);
     box-shadow: 0px 10px 20px rgba(0, 0, 0, 0.6);
     padding-right: 20px;
}

简单的你可以这样做。

 .plussymbol{
    font-size: 40px;
    color: #a4508b;
    background-color:transparent;
    border-radius: 20px;
    border: none;
    display: inline-block;
    cursor: pointer;
    margin-left: -60px;
   }
