问题描述
我是Web开发的初学者。
我不知道如何使用CSS将我的徽标摆在前面。我已经尝试将z-index设置为1000并将其位置设置为相对，但是仍然失败。
我该怎么做才最重要？

尝试一下：
<body>
<div class="wrapper">
<div class="info">
<div id="circle">
<div class="feature" id="f1"></div>
<div class="feature" id="f2"></div>
<div class="feature" id="f3"></div>
<div class="feature" id="f4"></div>
</div>
</div>
<nav>
<div class="logo">
<!-- I've commented the actual logo -->
<!-- <img src="images/resourses/logo.png" alt=""> -->
<h1>LOGO</h1>
</div>
<div class="navbar">
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">Phones</a></li>
<li><a href="#">Accessories</a></li>
<li><a href="#">Cart</a></li>
</ul>
</div>
</nav>
</div>
</body>
从本质上讲，通过将dev元素与info类一起放在导航之前，浏览器将优先于导航并在信息上显示导航。
,您的解决方案无效，因为您将z-index设置在圆圈后面已经存在的导航元素中。 z-index仅适用于容器内的所有元素，因此仅适用于nav元素内。
要解决此问题，请将z-index中的.info置于其他所有内容的后面，因此#circle内部的.info也位于其他所有内容的后面。
