当我调整浏览器窗口大小时，我的 div 降到底部，顶部有一个大空间。我希望即使调整窗口大小小于 div 大小，我的 div 也应保留在页面中央。在我的学校，他们没有教过这个，但我想在页面中心对齐这个 div
<!DOCTYPE html>

最佳答案
margin: auto; 是您所需要的。试试这个:
<style>
* {
margin: 0;
padding: 0;
}
/*html, body, .m {
height: 100%;
width: 100%;
}*/
.m {
opacity:1;
font-size: 0;
overflow: auto;
text-align: center;
margin: auto;
/*styling>>*/
background-color: #8F1C10;
}
.m::before {
content:'';
display: inline-block;
height: 100%;
vertical-align: middle;
}
.m>div {
display: inline-block;
font-size: 19px;
margin: 20px;
max-width: 320px;
min-height: 20px;
min-width: 300px;
padding: 14px;
vertical-align: middle;
/*styling*/
color:white;
background-color: #140A08;
outline:none;
}
</style>
