Border-radius 和 box-shadow 属性不影响代码答案

【问题标题】：Border-radius and box-shadow attributes doesnt affect the codeBorder-radius 和 box-shadow 属性不影响代码

【问题描述】：

大家好，我正在尝试将 box-shadow 和边框半径添加到我的 .card 元素中。但什么也没有发生。我该如何解决这个问题。为什么会这样？我有一个关于弹性盒的理论。

还有谁可以批评我的班级命名。我第一次在这里尝试使用 BEM 方法。为它们设计样式和命名它们的时间很长。我做得对吗？

【问题讨论】：

box-shadow 似乎工作正常，也许您发现了其他问题？关于边界半径属性，这是我们有时会遇到的一个非常常见的错误。只需将 .card 的 overflow 设置为 hidden。这样可以确保边框如您所愿，并且内部元素不会从其中出来。

标签： css flexbox border-radius

【解决方案1】：

编辑：

body：删除了overflow 和top 属性。添加了align-items: center;和height: 100vh；

body {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}

card: overflow: hidden; 隐藏角落加上box-shadow 和border-radius。

.card {
  box-shadow: 0 0 10px 10px lightskyblue;
  overflow: hidden;
  border-radius: 30px;
}

代码：

【解决方案2】：

我稍微清理了你的代码，border-radius 现在可以工作了，感谢@Robo Mop 对评论的洞察力，overflow:hidden; 已添加到卡片类中。我建议使用 Bootstrap，它会让你的生活更轻松，并尝试更好地组织你的 HTML 和 CSS。有了 cmets 就更好了。
