所以我创建了一个 gallery 页面来保存网站的图片，页面的图片似乎放在了我的导航栏的下拉框的前面.由于下拉框在图片后面，我无法点击它们来浏览其他页面.有没有一种方法可以让下拉框优先于图像？这样，我就可以像往常一样使用下拉框了.代码如下:
* {
padding: 0;
margin: 0;
box-sizing: border-box;
}
body {
font-family: sans-serif;
background-color: #788bc8;
min-height: 100vh;
overflow-x: hidden;
}
span {
color: white;
}
.navbar {
background-color: #d0f0c0;
height: 80px;
width: 100%;
display: flex;
align-items: center;
justify-content: space-between;
padding: 0 3%;
}
.logo {
font-size: 45px;
}
.logo a {
color: red;
text-decoration: none;
}
.navbar ul {
display: flex;
list-style-type: none;
}
.navbar ul li {
padding: 10px 25px;
position: relative;
}
.navbar ul li a {
color: black;
text-decoration: none;
font-size: 22px;
transition: all 0.2s;
}
.fas {
float: right;
margin-left: 10px;
padding-top: 3px;
}
.navbar ul li a:hover {
color: #4dac62;
}
.navbar ul li :where(.dropdownda, .dropdownfa) ul {
display: block;
margin: 10px;
text-align: center;
}
.navbar ul li :where(.dropdownda, .dropdownfa) ul li {
width: 200px;
padding: 10px;
}
.dropdownda,
.dropdownfa {
display: none;
position: absolute;
left: 0;
top: 100%;
background-color: #d0f0c0;
}
.navbar > ul > li:hover :where(.dropdownda, .dropdownfa) {
display: block;
}
.main {
position: relative;
justify-content: center;
align-items: center;
margin-top: 10px;
width: 100vw;
display: grid;
grid-template-columns: repeat(auto-fill, minmax(300px, 300px));
column-gap: 10px;
row-gap: 10px;
padding: 10px 0px;
}
img {
width: 300px;
height: 300px;
object-fit: cover;
object-position: center;
