html - 如何将 Bootstrap 形式的输入与输入组插件对齐？

Question

我有一个非常简单的 Bootstrap 3 表单，当我不使用 input-group-addon 时，我可以轻松(自动)对齐它。

在我的表单中使用它们后，无法对齐(由于添加了插件，带有插件的行更宽)

<form class="form-horizontal" role="form">

    <div class="form-group">
      <label for="product_name" class="col-sm-2 control-label">Product name</label>
      <div class="col-sm-4">
        <input type="text" class="form-control" id="product_name" placeholder="Product name">
      </div>
    </div>

    <div class="form-group">
      <label for="product_price" class="col-sm-2 control-label">Price</label>
      <div class="col-sm-4 input-group">
        <span class="input-group-addon">$</span>
        <input type="text" class="form-control bfh-number" id="product_price" placeholder="Price" data-min="0" data-max="9999999">
        <span class="input-group-addon">.00</span>
      </div>
    </div>

    <div class="form-group">
      <label for="product_description" class="col-sm-2 control-label">Description</label>
      <div class="col-sm-6">
        <textarea class="form-control" id="product_description" placeholder="Description" rows="5"></textarea>
      </div>
    </div>

    <div class="form-group">
      <div class="col-sm-offset-2 col-sm-10">
        <button type="submit" class="btn btn-default">Submit</button>
      </div>
    </div>
</form>

Answer 1

输入组的 Bootstrap 文档说:

Don't mix input-group with other components. (see:http://getbootstrap.com/components/#input-groups)

Do not mix form groups or grid column classes directly with input groups. Instead, nest the input group inside of the form group or grid-related element."

所以你不能在同一个类中混合使用“col-sm-4”和“input-group”。您必须创建 2 个 div 类，第一个是“col-sm-4”，另一个是“input-group”

<div class="col-sm-4">
  <div class="input-group">
    <span class="input-group-addon">$</span>
    <input type="text" class="form-control bfh-number" id="product_price" placeholder="Price" data-min="0" data-max="9999999">
    <span class="input-group-addon">.00</span>
  </div>
</div>
