我想创造记忆游戏。我想在4行中放置6张卡片。问题是DIV元素是＆＃34;背后＆＃34;卡片是可见的并且破坏了整个设计（我的代码中z-index3或.back class）。如果我放display.none back .class但是阻止卡片图片的问题，它会正常工作。
以下是我正在使用的代码
HTML
<body>
<div id="picbox">
<span id="boxbuttons">
<span class="button" id="rezz">
Rezultat
<span id="counter">0</span>
</span>
<span class="button" id="ttime">00 : 22</span>
<span class="button">
<a onclick="ResetGame();">Reset</a>
</span>
<span class="button">
<a onclick="MutedSound();">Mute sound</a>
</span>
</span>
<div id="boxcard" align="center">

它采用图像的整个背景，因此您最好将每个图像保留在仅限于该图像的特定div中。
