<div class="form-group">
    <label class="control-label col-md-3">X:</label>
    <div class="input-group col-md-7">
      <input class="form-control" type="text">
      <span class="input-group-addon">m</span>
    </div>
  </div>
  <div class="form-group">
    <label class="control-label col-md-3">Y:</label>
    <div class="input-group col-md-7">
      <input class="form-control" type="text">
      <span class="input-group-addon">m</span>
    </div>
  </div>
  <div class="form-group">
