html - 为什么将我的段落插入下一个 div 容器？

标签 html css

嘿，我有一些段落告诉你哪个盒子是哪个数字。但是每个段落都位于它应该命名的框下方。我真的有点不知道为什么会这样。

我所说的盒子在 div 容器“case”中。它们下面应该有一个输入层。预计稍后会向其中输入数字。

body {

最佳答案

由于您将 .box 的 100% 空间用于 input，因此没有更多空间用于 p 标记及其溢出下一个div，你可以使用position:absolute来设置顶部的数字，

#case .box{
  position:relative;
}
#case .box .id{
  position:absolute;
  top:10px;
  padding-left:5px;
}


body {
  background-color: dimgrey;

p {

  margin: 0 0 0 0;
}
input {
