在Bootstrap中，如何使文本左对齐？

Question

我希望“文本”与“关键文本”左对齐。目前它位于右侧：

我认为pl-0类可以做到这一点，但事实并非如此。在示例中，如何使“文本”与“关键文本”左对齐？我有以下JSFiddle和代码段：

.row {
  background: #f8f9fa;
  margin-top: 20px;
}

.col {
  border: solid 1px #6c757d;
  padding: 10px;
}

<script type="text/javascript" src="//code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<link rel="stylesheet" type="text/css" href="//stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.0/umd/popper.min.js"></script>
<script type="text/javascript" src="//stackpath.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">

<div class="modal-content pl-3 pr-3">
  <div class="modal-body">
    <div class="modal-body-scrolled border-primary border-bottom p-0 mt-2">
      <div class="form-row">
        <label id="lblFieldName" class="col-5 mb-0 text-primary font-weight-bold">Key Text</label>
        <div class="col-12">
          <div class="row ml-0 mr-0">
            <div class="row form-inline col-12 mt-2 mb-2 pt-2 pb-2 m-0">
              <div class="row col-12 pl-0 pr-0 mb-2">
                <label for="duration" class="col-2 pl-0">Text</label>
                <div class="col-10 pl-0 d-inline">
                  <textarea class="form-control" rows="2"></textarea>
                </div>
              </div>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

也添加justify-content-start类-请参见下面的演示

.row {
  background: #f8f9fa;
  margin-top: 20px;
}

.col {
  border: solid 1px #6c757d;
  padding: 10px;
}

<script type="text/javascript" src="//code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<link rel="stylesheet" type="text/css" href="//stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">

<div class="modal-content pl-3 pr-3">
  <div class="modal-body">
    <div class="modal-body-scrolled border-primary border-bottom p-0 mt-2">
      <div class="form-row">
        <label id="lblFieldName" class="col-5 mb-0 text-primary font-weight-bold">Key Text</label>
        <div class="col-12">

                <label for="duration" class="col-2 pl-0 justify-content-start">Text</label>
                <!-- ADDED 'justify-content-start' -->
                <div class="col-10 pl-0 d-inline">
                  <textarea class="form-control" rows="2"></textarea>
                </div>
              </div>
