Flexbox 表单未覆盖整个站点答案

【问题标题】：Flexbox Form not covering entire siteFlexbox 表单未覆盖整个站点
【发布时间】：2021-07-07 01:40:04
【问题描述】：

碰巧我的“表单”有 3 个 div “(.contact-in)”，我在我的 css 中用“:nth-child”来称呼它们，而使用 flex 我确实控制了它们在网站上的百分比，但在 x-轴。所以我的问题是我如何控制它们在 y 轴上的百分比，因为它们没有覆盖整个网站，例如我的页脚不会一直向下，因为我没有用内容覆盖整个页面。

后记：网站布局采用css网格。

【问题讨论】：

标签： html jquery css flexbox css-grid

【解决方案1】：

首先将html 和body 的height 设置为100%。

html, body{
    height: 100%;
}

如果要将页脚高度设置为80px，则将其设置为contenedor 类

.contenedor{
    ...
    grid-template-rows: repeat(2, auto) 80px;
}

当您可以使用grid-template-rows 使用grid 控制高度时，为什么要在内部设置高度80px。

#footer{
    ...
    height: 80px; // Should be avoided as per your design
    ...           // instead add height for whole footer in grid-tempate-rows
}

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

html,
body {
  height: 100%;
}

body {
  font-family: 'Poppins', sans-serif;
  background: #fff;
}
