我的目标是能够在 div 元素中垂直对齐动画文本。我曾尝试在这里寻找答案，但似乎找不到任何答案。具体来说，我尝试过 display:table-cell、vertical-align:middle 和 line-height:__，但它们都给出相同的结果。
let elemIds = ['a', 'b', 'c', 'd', 'e']
let currentAnimId = 0
function anims() {
let elem = document.getElementById(elemIds[currentAnimId])
let bgimg = document.getElementById('backgroundImg')
currentAnimId += 1
bgimg.style.animation="bgblur 5s";
elem.style.display = 'block'
elem.style.animation="textAnim 5s";
window.setTimeout(() => {
bgimg.style.animation="none";
elem.style.display = 'none'
elem.style.animation="none";
elem.style.webkitAnimation = 'none';
window.setTimeout(function() {
elem.style.webkitAnimation = '';
if (currentAnimId < elemIds.length) {
anims(currentAnimId)
} else {
console.log("You have reached the end of the text cycle.")
}
}, 1000);
}, 5000)
}
anims(currentAnimId)body {
margin: 0px;
padding: 0px;
font-family: 'Trebuchet MS', sans-serif;
}

vertical-align: middle;

PS:我只想让它垂直居中，而不是水平居中。 谢谢!
最佳答案
添加显示:flex； align-items: center; 到您的 textDiv。您的 textDiv 高度为 80%，如果您想在所有屏幕上垂直居中，则应将其设为 100%
let elemIds = ['a', 'b', 'c', 'd', 'e']
let currentAnimId = 0
function anims() {
let elem = document.getElementById(elemIds[currentAnimId])
let bgimg = document.getElementById('backgroundImg')
currentAnimId += 1
bgimg.style.animation="bgblur 5s";
elem.style.display = 'block'
elem.style.animation="textAnim 5s";
window.setTimeout(() => {
bgimg.style.animation="none";
elem.style.display = 'none'
elem.style.animation="none";
elem.style.webkitAnimation = 'none';
window.setTimeout(function() {
elem.style.webkitAnimation = '';
if (currentAnimId < elemIds.length) {
anims(currentAnimId)
} else {
console.log("You have reached the end of the text cycle.")
}
}, 1000);
}, 5000)
}
anims(currentAnimId)body {
margin: 0px;
padding: 0px;
