margin-top 不会移动单个元素

Question

我正在尝试制作一个与名称框水平的评论框，因为文本框固定在顶部。当我尝试在文本区域和表单上应用 margin-top 时，它会将名称框和整个配置文件一起向下移动。有没有办法将文本区域向下移动，而不影响其他任何东西。这是我的代码：

body {
 margin: 0;
}
p.name {
 font-family: "Roboto";
 margin-top: 90px;
 margin-left: 50px;
 margin-bottom: 0;
 border: 1px solid black;
 display: inline-block;
 padding: 20px 70px;
 font-size: 25px;
}
div.info {
 margin-left: 50px;
 border: 1px solid black;
 padding: 20px 13.5px 20px;
 border-top: none;
 display: inline-block;
 margin-bottom: 0;
}
div.date {
 margin-left: 50px;
 border: 1px solid black;
 border-top: none;
 display: inline-block;
 padding: 0px 17px 0px;
 text-align: center;
}
form {
 display: inline-block;
 margin-left: 100px;
}
textarea {
  width: 300px;
  height: 150px;
  display: inline-block;
  padding: 12px 20px;
  box-sizing: border-box;
  border: 2px solid #ccc;
  border-radius: 4px;
  background-color: #f8f8f8;
  font-size: 16px;
  resize: none;
}

Answer 1

我看过你的代码，发现了你的问题，我的建议是在你的.textarea class中添加两个属性，即position:relative和top 根据您的要求。

textarea{
   position:relative;
   top:100px;
}

Answer 2

另一个选项是给 label 标签放置一个位置，这个标签有一个相对位置，你可以改变 top 和 right 来移动。

body {
 margin: 0;
}
p.name {
 font-family: "Roboto";
 margin-top: 90px;
 margin-left: 50px;
 margin-bottom: 0;
 border: 1px solid black;
 display: inline-block;
 padding: 20px 70px;
 font-size: 25px;
}
  
div.info {
 margin-left: 50px;
 border: 1px solid black;
 padding: 20px 13.5px 20px;
 border-top: none;
 display: inline-block;
 margin-bottom: 0;
}
label{
    position:relative;
    top:50px;
    right:100px;
}
div.date {
 margin-left: 50px;
 border: 1px solid black;
 border-top: none;
 display: inline-block;
 padding: 0px 17px 0px;
 text-align: center;
}
form {
 display: inline-block;
 margin-left: 100px;
}
textarea {
  width: 300px;
  height: 150px;
  display: inline-block;
  padding: 12px 20px;
  box-sizing: border-box;
  border: 2px solid #ccc;
  border-radius: 4px;
  background-color: #f8f8f8;
  font-size: 16px;
  resize: none;
}
