我不知道如何用影片顯示選單。我希望它向下滑動并在切換時備份。我愿意尋求任何解決方案。
const toggleButton = document.getElementById('toggleButton');
const naviList = document.getElementById('navi-lista');
toggleButton.addEventListener('click', () => {
naviList.classList.toggle('active');
})* {

uj5u.com熱心網友回復：
您可以嘗試使用 max-height 作為屬性來設定影片：
@media all and (max-width: 480px) {
.navbar {
position: relative;
padding: 10px 15px;
}
.menu {
display: block;
cursor: pointer;
}
.lista-nav .elementlisty {
display: block;
padding: 10px;
border-top: solid 1px white;
}
.lista-nav {
transition: max-height .3s;
list-style-type: none;
width: 100%;
text-align: center;
position: absolute;
top: 100%;
left: 0;
right: 0;
background-color: rgb(31, 31, 31);
max-height: 0;
overflow: hidden;
}
.logo-kontener {
width: 100%;
}
.primary-icon {
margin-left: 10px;
margin-top: 10px;
}
.active {
max-height: 500px;
}
}
