Question

我试图在输入字段顶部叠加标签。问题是，我使用flex并且它似乎没有相同的工作方式。

我在Google上寻找解决方案，但似乎我能找到的大部分内容都与通过弹性定位对齐项目有关，但我需要将标签移动后并排排列。。我已提供代码，以防我难以理解我需要的内容。

我也在这里寻找解决方案，但我还没有发现任何特定于我的问题。目前，我有覆盖字段的标签，但我无法让字段彼此对齐。此外，我相信你们中的一些人会注意到较小屏幕中的标签下方的字段。

所以，为了确保我澄清，我不确定。当标签与输入重叠时，我需要我的输入字段并排对齐。（白板草图：https://sketchboard.me/dADoYPlJsIfT#/）

Answer 1

他们在两个单独的行上的原因是因为，您正在使用标签的相对定位。相对定位确实会移动标签，但是如果你没有移动它们，它们仍会占用它们所占用的空间。你需要使用绝对定位。

你似乎已经确定了相对于几乎所有事情的位置。您需要将标签绝对定位到字段中。我建议将输入和标签环绕在具有相对位置的div中，然后使用绝对定位来定位标签。

form {
  display: flex
}

.form-field {
  position: relative
}

label {
  position: absolute;
  margin-left: 5px;
  top: 50%;
  transform: translate(0%, -50%)
}

<form>
  <div class="form-field">
    <label>Label1</label>
    <input type="text" />
  </div>
  <div class="form-field">
    <label>Label1</label>
    <input type="text" />
  </div>
</form>
