基本上我试图做的就是当我将鼠标悬停在链接上时，图像会显示在链接后面。当将鼠标悬停在链接上时，使图像显示在背景中
这是我的CSS迄今：
@charset "UTF-8";
#css-zen-garden {
background-image: url(images/batswarm.jpg);
background-repeat: no-repeat;
background-color: #535353
}
#container{
margin: 10%;
background-color: silver;
border: white solid 3px;
padding: 5px;
}
h1, h2, h3 {
text-transform: uppercase;
}
a {
color: white;
}
a:hover {
background-image: url(images/batman-logo.gif);
color: #535353;
}
header ~ div, article > div {
border-bottom: 3px dotted #535353
}
::selection {
background-color: red;
}
我答：悬停，我想这种形象出现在链接的背景下，不能低于它。任何对此的帮助将非常感激。我的HTML代码也在底部。

<h3><span>The Road to Enlightenment</span></h3>
<p class="p1"><span>Littering a dark and dreary road lay the past relics of browser-specific tags, incompatible <abbr title="Document Object Model">DOM</abbr>s, and broken <abbr title="Cascading Style Sheets">CSS</abbr> support.</span></p>
<p class="p2"><span>Today, we must clear the mind of past practices. Web enlightenment has been achieved thanks to the tireless efforts of folk like the <abbr title="World Wide Web Consortium">W3C</abbr>, <abbr title="Web Standards Project">WaSP</abbr> and the major browser creators.</span></p>
<p class="p3"><span>The css Zen Garden invites you to relax and meditate on the important lessons of the masters. Begin to see with clarity. Learn to use the (yet to be) time-honored techniques in new and invigorating fashion. Become one with the web.</span></p>

<h3><span>So What is This About?</span></h3>
<p class="p1"><span>There is clearly a need for <abbr title="Cascading Style Sheets">CSS</abbr> to be taken seriously by graphic artists. The Zen Garden aims to excite, inspire, and encourage participation. To begin, view some of the existing designs in the list. Clicking on any one will load the style sheet into this very page. The code remains the same, the only thing that has changed is the external .css file. Yes, really.</span></p>
<p class="p2"><span><abbr title="Cascading Style Sheets">CSS</abbr> allows complete and total control over the style of a hypertext document. The only way this can be illustrated in a way that gets people excited is by demonstrating what it can truly be, once the reins are placed in the hands of those able to create beauty from structure. To date, most examples of neat tricks and hacks have been demonstrated by structurists and coders. Designers have yet to make their mark. This needs to change.</span></p>

<!-- - - - - - - - - - PARTICIPATION - - - - - - - - - -->
<div id="participation">
<h3><span>Participation</span></h3>
<p class="p1"><span>Graphic artists only please. You are modifying this page, so strong <abbr title="Cascading Style Sheets">CSS</abbr> skills are necessary, but the example files are commented well enough that even <abbr title="Cascading Style Sheets">CSS</abbr> novices can use them as starting points. Please see the <a href="http://www.mezzoblue.com/zengarden/resources/" title="A listing of CSS-related resources"><abbr title="Cascading Style Sheets">CSS</abbr> Resource Guide</a> for advanced tutorials and tips on working with <abbr title="Cascading Style Sheets">CSS</abbr>.</span></p>
<p class="p2"><span>You may modify the style sheet in any way you wish, but not the <abbr title="HyperText Markup Language">HTML</abbr>. This may seem daunting at first if you’ve never worked this way before, but follow the listed links to learn more, and use the sample files as a guide.</span></p>
<p class="p3"><span>Download the sample <a href="#" title="This page's source HTML code, not to be modified.">html file</a> and <a href="#" title="This page's sample CSS, the file you may modify.">css file</a> to work on a copy locally. Once you have completed your masterpiece (and please, don’t submit half-finished work) upload your .css file to a web server under your control. <a href="http://www.mezzoblue.com/zengarden/submit/" title="Use the contact form to send us your CSS file">Send us a link</a> to the file and if we choose to use it, we will spider the associated images. Final submissions will be placed on our server.</span></p>

<h3><span>Benefits</span></h3>
<p class="p1"><span>Why participate? For recognition, inspiration, and a resource we can all refer to when making the case for <abbr title="Cascading Style Sheets">CSS</abbr>-based design. This is sorely needed, even today. More and more major sites are taking the leap, but not enough have. One day this gallery will be a historical curiosity; that day is not today.</span></p>
</div>
<!-- - - - - - - - - - REQUIREMENTS - - - - - - - - - -->
<div id="requirements">
<h3><span>Requirements</span></h3>
<p class="p1"><span>We would like to see as much <abbr title="Cascading Style Sheets, version 1">CSS1</abbr> as possible. <abbr title="Cascading Style Sheets, version 2">CSS2</abbr> should be limited to widely-supported elements only. The css Zen Garden is about functional, practical <abbr title="Cascading Style Sheets">CSS</abbr> and not the latest bleeding-edge tricks viewable by 2% of the browsing public. The only real requirement we have is that your <abbr title="Cascading Style Sheets">CSS</abbr> validates.</span></p>
<p class="p2"><span>Unfortunately, designing this way highlights the flaws in the various implementations of <abbr title="Cascading Style Sheets">CSS</abbr>. Different browsers display differently, even completely valid <abbr title="Cascading Style Sheets">CSS</abbr> at times, and this becomes maddening when a fix for one leads to breakage in another. View the <a href="http://www.mezzoblue.com/zengarden/resources/" title="A listing of CSS-related resources">Resources</a> page for information on some of the fixes available. Full browser compliance is still sometimes a pipe dream, and we do not expect you to come up with pixel-perfect code across every platform. But do test in as many as you can. If your design doesn’t work in at least IE5+/Win and Mozilla (run by over 90% of the population), chances are we won’t accept it.</span></p>
<p class="p3"><span>We ask that you submit original artwork. Please respect copyright laws. Please keep objectionable material to a minimum; tasteful nudity is acceptable, outright pornography will be rejected.</span></p>
<p class="p4"><span>This is a learning exercise as well as a demonstration. You retain full copyright on your graphics (with limited exceptions, see <a href="http://www.mezzoblue.com/zengarden/submit/guidelines/">submission guidelines</a>), but we ask you release your <abbr title="Cascading Style Sheets">CSS</abbr> under a Creative Commons license identical to the <a href="http://creativecommons.org/licenses/by-nc-sa/1.0/" title="View the Zen Garden's license information.">one on this site</a> so that others may learn from your work.</span></p>

您的问题中缺少太多的细节以给出具体的答案。根据你的CSS，image *应该*显示为a元素背景的一部分，但是，有一些问题：（a）链接有多大？ （b）链接中包含哪些内容？ （c）链接是否显示：block？ （d）图像是否有填充，空白等将其压下？ –
链接很小，只有两个字，说“html链接”。该链接下载示例html页面。没有链接不显示：block ;.没有其他人围绕链接。如果你需要html，我可以把它放。此外，我的照片相当大，所以我可能不得不编辑它，并使其足够小，以适应微小的链接空间。 – shoeman23
