z-index不適用於<input>

Question

我有一個<svg>，我想包圍<input>文本框。我已將<svg>的z-index設置爲高於包含<div>和<input>文本框的z-index甚至更​​高，但<svg>仍位於<input>文本框的頂部。

<form id="before-list" onsubmit="return false;"> 
    <label for="search" class="ui-hidden-accessible">Label:</label> 
    <div class="ui-input-search ui-body-inherit ui-corner-all ui-shadow-inset ui-input-has-clear"><span class="ui-helper-hidden-accessible" aria-live="polite" role="status"></span> 
     <input style="z-index: 10000;" autocomplete="off" class="ui-autocomplete-input" name="search" id="search" value="" placeholder="placeholder" data-type="search" type="text"><a href="#" class="ui-input-clear ui-btn ui-icon-delete ui-btn-icon-notext ui-corner-all ui-input-clear-hidden" title="Clear text">Clear text</a> 
    </div> 
</form> 
<svg style="position: absolute; left: 0px; top: 0px; z-index: 1001;" xmlns="http://www.w3.org/2000/svg" width="396" version="1.1" height="78">

</svg> 

我怎樣才能獲得的文本框中輸入要對SVG的頂部？

（使用Firefox 24 & jQuery Mobile的1.4.0）

我剛加了個位置：relative;早在您的新小提琴，和它的作品再次

的z-index需要它的元素有一個位置：相對或固定的，或絕對爲它工作
