Firefox和Linux中的设计问题苹果浏览器

Question

目前我在Firefox和Safari中遇到了设计问题。它看起来在Firefox中是正确的，但在Safari中它从顶部占用了一些空间。

如何删除多余的空格并在同一行显示我的第三个span？

CSS：

<style type="text/css">

span#mrList { padding-right:20px;}

    /* Start CSS for MR List */
    .checklist {
        border: 1px solid #ccc;
        list-style: none;
        height: 20em;
        overflow: auto;
        width: 26em;
        -moz-border-radius: 10px;
        -webkit-border-radius: 10px;
        border-radius: 10px; /* future proofing */
        -khtml-border-radius: 10px; /* for old Konqueror browsers */
        border-style:none;
        background-color:#FFF
    }
     span#mrList {
         float:right;
         padding:0px 160px 0px 20px;
    }
    .checklist label input{
    width:30px;
    padding-right:50px;
    }

    .checklist, .checklist li { margin: 0; padding-top:0px; }

    .checklist label {
    display: block;
    padding-left: 25px;
    text-indent: -25px;
    font: normal normal normal 14px helvetica, Arial;
    color: #888;
    }

    .checklist label:hover { background: #777; color: #fff;  }
    /* End CSS for MR List */
</style>

HTML：

<form name="message_frm" id="message_frm" method="post" action="">
        <input type="hidden" name="action" value="reg" />

          <span  id="docFilter">MR/User :
              <span id="docFilterContainer">
                  <select name="sel_filter2" id="sel_filter2"  onchange="getFilter(this.value);">

我不确定这是否有帮助，因为它有点hacky，但您始终只能使用以下目标定位webkit浏览器：

@media screen and (-webkit-min-device-pixel-ratio:0) {


 span {  }

}
