我正在尝试创建一个登录页，但我发现很难放置导航栏并保持英雄内容的原样。我尝试过使用flexbox，但当我相对定位内容并使用底部50%将导航栏带到角落时，它似乎不起作用。
body, html {
height: 100%;
margin: 0;
font-size: 20px;
}
.hero-image {
background-image: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url("building.jpg");
height: 50%;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
position: relative;
}
.hero-text {
text-align: center;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
color: white;
}
.btn {
text-transform: capitalize;
font-size: 1rem;
border-radius: 1rem;
border-color: white;
}
.btn:hover {
background-color: aqua ;
border-color: aqua;
}
.main {
position: relative;
display: flex;
}
li {
list-style-type: none;
display: flex;
}
li a {
text-decoration: none;
}<body>
<div class="hero-image">
<div class="hero-text">
<h1>Welcome to ZERG</h1>
<p>Where we Strive for a better Future</p>
<button class="btn">Find out More</button>
</div>
</div>
<nav class="main">
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">Pricing</a></li>
<li><a href="#">Contact </a></li>
</ul>
</nav>
</body>你是指底部导航栏吗？还是一个奇怪的水平在中间的一个？下面是一个底部导航栏的例子。运行代码段并放入整页。
