最小高度不扩展

Question

所以，我正在制作一个网络作品集作为我的项目，我设法找到了一个问题。当我在“关于我”部分使用 min-height 时，该部分似乎没有根据内容调整其高度。可能是因为我在导航栏中使用了浮动，但我不太确定。如果有人可以帮助我，我将不胜感激。提前致谢。

这是我的 HTML 和 CSS 代码：

/* global */

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  font-family: "Montserrat", sans-serif;
  scroll-behavior: smooth;
}

a {
  text-decoration: none;
}


/* animations */

@keyframes bounce {
  0% {
    transform: translateY(0px);
  }
  50% {
    transform: translateY(15px);
  }
  100% {
    transform: translateY(0px);
  }
}

@keyframes appear {
  0% {
    opacity: 0;
  }
  50% {
    opacity: 0;
  }
  100% {
    opacity: 1;
  }
}

@keyframes popup {
  0% {
    transform: translateY(200px);
    opacity: 0;
  }
  100% {
    transform: translateY(0);
    opacity: 1;
  }
}

这是我面临的问题： The background color doesn't cover the bottom area

Answer 1

min-height: body 元素的 100vh 应该可以解决问题。在这里，100vh 表示初始主体高度将占视口高度的 100%，更好用:

height : 100vh;

Answer 2

去掉高度属性

 .about .container {
        width: 100%;
        display: flex;
        flex-direction: column;
        justify-items: center;
        align-items: center;
}

最小高度不扩展

Min-height not expanding

html

css
