我看过其他的教程,教你在内容很少的时候如何用css网格把页脚贴在底部,但是我想不出来。
如果你能帮上忙,那就太好了。我正在学习css网格,我花了好几天的时间断断续续地试图弄清楚它。

* {
  margin: 0;
  padding: 0;

html body {
  height: 100%;
  width: 100%;
}

.grid {
  min-height: 100%;
  display: grid;

  grid-template-rows: 50px 1fr auto;
  grid-row-gap: 10px;

.main {

.footer {

  background-color: black;
}

        <div class="footer">Footer

        </div>

      </div>

</html>

我知道这个问题已经问过了,但我正在寻找一个修复我自己的代码。抱歉,如果我错过了一些明显的。

你可以简单地使用Viewport Height(vh)来固定窗口底部的页脚。这个单位基于视口的高度。1vh的值等于视口高度的1%。所以这里我只设置了. gridmin-height:100vh而不是最小高度:100%

* {
        margin: 0;
        padding: 0;
        color: #ffffff;
        font-family: helvetica;
      }

      body {
        background-color: #191919;
      }

      html body {
        height: 100%;
        width: 100%;
      }

      .grid {
        min-height: 100vh;
        display: grid;
        grid-template-columns: 10% 40% 40% 10%;
        grid-template-rows: 50px 1fr auto;
        grid-row-gap: 10px;
        grid-template-areas:
        "header header header header"
        ". main main ."
        "footer footer footer footer";
      }
      /*Header*/

      .header {
        grid-area: header;
        background-color: red;
        display: grid;
        position: fixed;
        width: 100%;
        grid-template-columns: 40% 60%;
        grid-template-areas:
        "title navigation"
      }

      .title {
        grid-area: title;
        text-align: center;
      }

      .navigation {
        grid-area: navigation;
      }

      .title .navigation {
      }

      /*Main*/

      .main {
        margin-top: 50px;
        grid-area: main;
        background-color: #323232;
        border-radius: 10px;
      }

      /*Footer*/

      .footer {
        grid-area: footer;
        background-color: black;
      }

这是一个老问题,但这里是我的答案无论如何...
使用css变量作为页脚高度和页眉高度。

:root {
   --header-height: 56px;
   --footer-height: 56px;
}

使用css calc function单位设置主元素的最小高度,方法是从full viewport height中减去页脚和页眉高度。

main {
   min-height: calc(100vh - (var(--footer-height) + var(--header-height)));
}

超级简单的解决方案:
将以下代码添加到.footer类中:

position:absolute;
  bottom:0;
  left:0;
  right:0;

完整的footer类看起来如下所示:

.footer {
  grid-area: footer;
  background-color: black;
  position:absolute;
  bottom:0;
  left:0;
  right:0;
}

这就是你所要做的一切!下面是它的渲染方式:

这是一个example,代码如下。

    • 中央支助组**
html {
  /* min-height on body doesn't work unless it's parent (html) has an explicit height */
  height: 100%;
}

body {
  /* min-height because content larger than 100% of the view height should scroll */
  min-height: 100%;
  display: grid;
  /* we have 3 rows: header, main and footer. We want the main content to fill the empty space when the content doesn't fill the viewport */
  grid-template-rows: auto 1fr auto;
}
    • 超文本标记语言**
