我正在进行自定义下拉导航,但是当它切换徽标时,在蓝色div所代表的此codepen中,会转到导航的底部。我一直试图解决这个问题一段时间,并希望得到任何帮助。
这是我的代码:
HTML
<div class='container-fluid nav'>
<div class='container'>
<div class = 'nav__btn--toggle u-inlineBlock u-center' onclick="animateNavbarToggle(this); toggleDropdown();">
<div class = 'nav__btn bar1'></div>
<div class = 'nav__btn bar2'></div>
<div class = 'nav__btn bar3'></div>
</div>
<ul class = "nav__dropdown">
<li>Home</li>
<li>About</li>
<li>Work</li>
<li>Blog</li>
<li>Contact</li>
</ul>
<div class='nav__brand u-inlineBlock'>
logo
</div>
</div>
</div>
CSS
.nav__dropdown {
padding-left: 0;
margin-top: 75px;
list-style: none;
text-align: center;
box-sizing: border-box;
display: none;
}
.nav__dropdown li {
font-size: 20px;
padding: 25px;
width: 40%;
background: white;
border-bottom: 1px solid black;
}
.nav__dropdown li:last-child{
border-bottom: none;
}
.nav__dropdown li:hover{
background: black;
color: seashell
}
.u-inlineBlock {
display: inline-block;
}
JS
function toggleDropdown(x) {
$('.nav__dropdown').slideToggle(500);
}
在此之后,我会尝试在右侧添加一个子菜单,所以如果你能指出我正确的道路,这将是伟大的
(请注意,这对我来说只是一个奖励,我不在乎你是否对我没有帮助,所以不要因为太宽泛或类似的东西而投票。我也看到了类似的东西。问题,但他们没有帮助)
提前致谢!

只需在ul之前移动徽标,然后从ul中删除margin-top
。如果您希望切换按钮和子菜单与白色标题齐平,请删除.nav { height: 75px; }
function animateNavbarToggle(x) {
x.classList.toggle("toggled");
}
function toggleDropdown(x) {
$('.nav__dropdown').slideToggle(500);
}

尝试将position: fixed
添加到您的nav__dropdown
CSS
.nav__dropdown {
padding-left: 0;
margin-top: 75px;
list-style: none;
text-align: center;
box-sizing: border-box;
display: none;
position: fixed;
}
位置fixed
基本上会删除文档窗口流中的内容,这样就不会导致与徽标进行任何交互。
