下拉菜单 Hover 似乎不起作用？

Question

Dropdown menu hover is actually working but shows a different menu list element when I start pointing the mouse. For example, I was trying to choose a 'Shop' menu, when it hovers its shows an 'About' menu instead of hovering a list from the 'Shop' menu.

Also hover elements not displaying property... Could you guys help me?

here's are the codes:

 var ul = document.getElementById('navClass'); window.onscroll = () => { if(window.scrollY < 10){ ul.style.marginTop = '70px' ul.style.backgroundColor = "transparent"; ul.style.boxShadow = "none"; } else{ ul.style.marginTop = '0px' ul.style.backgroundColor = "#111"; ul.style.boxShadow = "0px 0px 20px black"; } }

 *{ padding:0px; margin:0px; box-sizing: border-box; } #navClass { color: white; padding: 3rem 0rem 1rem 0rem; display: flex; justify-content: space-between; align-items: center; width: 100%; height: 7rem; margin-top: 70px; position: fixed; transition-duration: 300ms; transition-property: all; transition-timing-function: cubic-bezier(0.4, 0, 0.2, 1); transition-duration: 150ms; z-index: 10; } #navClass ul { display: flex; list-style-type: none; font-size: 1.7vw; margin-left: 150px; text-shadow: 2px 2px black; } #navClass li { padding: 0 10px 0 10px; cursor: pointer; font-size: 1.7vw; border-radius: 5px; transition:.5s; text-shadow: 2px 2px black; color: white; text-decoration:none; display:inline-block; z-index: 500; } #navClass a{text-decoration:none; color: white; } #navClass ul li:hover{ background:orange; border-radius: 5px 5px; } ul.sub-menu{ position:absolute; background-color: orange; list-style-type:none; margin-top:-5px; left:200px; width:auto; padding-left:0px; opacity:0; display: flex; align-items: center; flex-direction:column; justify-content: space-between; } ul.sub-menu li { display: inline-block; padding-left:0px; } ul.sub-menu li a:hover{ background-color: orangered; } #navClass li:hover.sub-menu { z-index:100; opacity:1; } /*'nav img' is a company Logo image*/ nav img { height: 5rem; left:-15px; position:relative; top: -60px; }.fa-bag-shopping{ position:relative; left:-1%; top:-80px; font-size:2vw; text-shadow: 2px 2px black; }.login{ position:relative; left: 4%; top:-80px; font-size: 1vw; text-shadow: 2px 2px black; padding-right:30px; text-decoration:none; }.fa-magnifying-glass{ left: 280px; position:relative; text-shadow: 2px 2px black; font-size:1.5em; }

I tried to fix it for many hours but it doesn't seem to work and I'm almost out of my mind... Please help.

There is an issue with your CSS you are using the position fixed property for your submenu class that is opening your all submenus at a fixed position. I have edited the CSS please have a look and let me know if it solves the issue.

 var ul = document.getElementById('navClass'); window.onscroll = () => { if(window.scrollY < 10){ ul.style.marginTop = '70px' ul.style.backgroundColor = "transparent"; ul.style.boxShadow = "none"; } else{ ul.style.marginTop = '0px' ul.style.backgroundColor = "#111"; ul.style.boxShadow = "0px 0px 20px black"; } }

 *{ padding:0px; margin:0px; box-sizing: border-box; } #navClass { color: white; padding: 3rem 0rem 1rem 0rem; display: flex; justify-content: space-between; align-items: center; width: 100%; height: 7rem; margin-top: 70px; position: fixed; transition-duration: 300ms; transition-property: all; transition-timing-function: cubic-bezier(0.4, 0, 0.2, 1); transition-duration: 150ms; z-index: 10; } #navClass > ul { display: flex; list-style-type: none; font-size: 1.7vw; margin-left: 150px; text-shadow: 2px 2px black; } #navClass li { padding: 0 10px 0 10px; cursor: pointer; font-size: 1.7vw; border-radius: 5px; transition:.5s; text-shadow: 2px 2px black; color: white; text-decoration:none; display:inline-block; z-index: 500; } #navClass a{text-decoration:none; color: white; } #navClass ul li:hover{ background:orange; border-radius: 5px 5px; } ul.sub-menu li a:hover{ background-color: orangered; } /*'nav img' is a company Logo image*/ nav img { height: 5rem; left:-15px; position:relative; top: -60px; }.fa-bag-shopping{ position:relative; left:-1%; top:-80px; font-size:2vw; text-shadow: 2px 2px black; }.login{ position:relative; left: 4%; top:-80px; font-size: 1vw; text-shadow: 2px 2px black; padding-right:30px; text-decoration:none; }.fa-magnifying-glass{ left: 280px; position:relative; text-shadow: 2px 2px black; font-size:1.5em; } /* Hide Dropdowns by Default */ #navClass ul ul { display: none; position: absolute; margin-left: 0; background-color: orange; list-style-type:none; padding-left:0px; align-items: center; flex-direction:column; justify-content: space-between; } /* Display Dropdowns on Hover */ #navClass ul li:hover > ul { display: flex; }
