如何使textarea与select一样高，同时仍然有响应？

Question

我有一个我正在开发的表单，虽然我可以让表单字段响应宽度，但textarea框比右边的选择字段略高。如何保持这两个相同的高度，同时保持对移动设备的响应？

这是形式的codepen。以下是代码：

      <div class="row">
        <div class="col-md-6">
          <div class="control-group">
            <div class="form-group floating-label-form-group controls">
              <label for="00NW0000001Zjiv" class="control-label" style="font-weight:300">Truck Model(s)</label>
              <textarea id="00NW0000001Zjiv" name="00NW0000001Zjiv" type="text" class="form-control input-lg" rows="5"></textarea><span class="help-block bg-danger"></span>
            </div>
          </div>
        </div>
        <div class="col-md-6">
          <div class="control-group">
            <div class="form-group floating-label-form-group controls">
              <label for="00NW0000001Zjje" class="control-label" style="font-weight:300">State(s) in which the truck(s) run</label>
              <select id="00NW0000001Zjje" name="00NW0000001Zjje" multiple="multiple" class="form-control input-lg">

通过手动高度给textarea可以实现。因此，请在媒体查询中为textarea提供高度。

通过这种方式，您也可以实现响应能力。

我希望这可以帮助你JSFiddle Link

<div class="row">
        <div class="left">
            <label for="first-name">First Name</label>
                <input type="text" name="first-name" placeholder="First Name" id="first-name" required="required"  />

        </div>
        <div class="right">
            <label for="details">Details</label>
            <textarea name="details" placeholder="Details" id="details" required></textarea>
        </div>
    </div>

CSS：

 @media only screen and (min-width: 600px) {

        textarea { height: calc(100% - 0.75em); /* 100% fill height, minus height of details label */ }
    }
