当我在移动视图上调整页面大小时，为什么页面不会增长 html 元素页面？答案

【问题标题】：Why page don't grow the html element page when I resize the page on mobile view?当我在移动视图上调整页面大小时，为什么页面不会增长 html 元素页面？
【发布时间】：2022-01-12 14:24:57
【问题描述】：

我在页面中有一个简单的网格。在桌面视图中，项目是水平对齐的，当它低于 60px 时，项目是垂直的。到目前为止，一切都很好。我在桌面模式下的页面高度已满。
当我在移动视图上调整页面大小时，HTML 页面的元素不会随着其中内容元素的高度而增长。它溢出了。为什么？

【问题讨论】：

请将您的 HTML 和 CSS 添加到问题中。

标签： html css flexbox media-queries viewport

【解决方案1】：

您的问题是您将section.areas 高度设置为静态值。

.areas {
    padding: 2rem;
    height: 100vh;
}

如果您将height 属性更改为min-height，则该部分将永远不会小于全屏，但 DOM 将允许该部分超过全屏。

.areas {
    padding: 2rem;
    min-height: 100vh;
}

【讨论】：

【解决方案2】：

您的区域类似乎设置了高度。

如果您添加它是为了在数据有限时保持高度，您可以在您的区域类中将height: 100vh更改为min-height: 100vh。

这是一个有效的codepen。
