如何在彼此之间对齐输入字段而不会遇到标签宽度的麻烦

Question

我正在尝试设计一种表单，以使输入字段相互之间。我尝试通过在输入字段之前给标签指定宽度来尝试这样做，即使标签文本较短，空格也一样。它在youtube视频中有效，但由于某种原因我无法使其正常工作。无论我给标签加上多少宽度，都不会改变。我想这是我犯的一个非常简单的错误，这几乎让我感到沮丧。

  overflow-y: hidden;
  margin: 0;

  margin-left: 15%;
  margin-right: 15%;

您在标签样式上缺少display:inline-block;。默认情况下，标签元素是内联的，要分配宽度，您需要将其更改为inline-block。

检查以下代码段：

body,
html {
  background-color: aquamarine;
  background-image: url(../background.jpg);
  height: 100%;
  overflow-y: hidden;
  margin: 0;
}

#Wrapper {
  margin-left: 15%;
  margin-right: 15%;
  height: 100vh;
}
