如何使网站垂直响应?

我有一个网页,并且所有内容都包裹着“正文”。但是,当我响应此网页并希望正文放大网页内容时,正文会停止垂直放大内容。当我增加宽度但不垂直时,确实会扩大内容。我不要多余的黑色区域。

body {

这实际上取决于您要实现的目标,但是通常,您可以使用媒体查询来确定高度,并将它们与宽度查询结合起来。

@media screen and (max-width: 800px) , screen and (max-height: 600px) {
  ...
}

默认情况下,您的网页会根据内容的高度进行垂直缩放。要始终使它至少为一个视图高度,可以将此规则插入到CSS中:

html, body {
    min-height: 100vh;
}
