我的一个元素与另一个元素重叠

Question

我是网络开发的初学者。

我不知道如何使用 CSS 将我的徽标放在前面。我已经尝试将 z-index 设置为 1000 并将位置设置为 relative，但仍然失败。

我在这里提供了完整的代码，因为我无法弄清楚我哪里出错了！

如何将元素置于最前面？

¯\_(ツ)_/¯

Answer 1

试试这个：

<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>

基本上，通过将带有信息 class 的 dev 元素放在导航之前，浏览器将优先显示导航而不是信息。

Answer 2

您的解决方案无效，因为您将 z-index 设置在已经位于圆圈后面的导航元素内部。 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 .info 的 z-index 设置在其他所有内容的后面，因此 .info 中的 #circle 也会在其他所有内容的后面。

*{
    margin: 0;
    padding: 0;
}
body{
    font-family: 'Gill Sans', 'Gill Sans MT', Calibri, 'Trebuchet MS', sans-serif;
    background: linear-gradient(to right, #9c27b0, #8ecdff);
}

.logo{
    display: inline-block;
    position: relative;
    flex-basis: 20%;
    z-index: 1;
}
.logo img{
    width: 13vw;
    margin-left: 1vw;
    margin-top: 1vw;
}
nav{
    position: sticky;
}
.navbar{
    float: right;
}
.navbar ul{
    display: flex;
    list-style: none;
}
.navbar ul li{
    margin-top: 1.8vw;
    margin-right: 3vw;
}
.navbar ul li a{
    text-decoration: none;
    color: #fff;
}
.info{
    /* set the z-index of the entire info to be behind everything else */
    z-index: -1;
    width: 60vw;
    height: 140vh;
    position: absolute;
    top: 50%;
    left: -10%;
    transform: translateY(-50%);
}
#circle{
    width: 60vw;
    height: 140vh;
    position: absolute;
    top: 50%;
    transform: translateY(-50%);
    border-radius: 50%;
    background-color: #ccc ;    
}
