html - 使用Bootstrap4对齐表单组件

我正在bootstrap4的帮助下制作表格，它必须像这样：



由于我已经通过阅读Bootstrap4中的内容来完成家庭作业的阅读。并尽我最大的努力使表格像这样，但是毕竟，我没有得到想要的结果。我已经使用来达成结果，但是没有运气。

这是我到目前为止尝试过的代码：

<div class="form-container">
   <form>
    <div class="form-group row">
      <label for="inputPhone" class="col-sm-2 col-form-label">Phone</label>
      <div class="col-sm-10">
        <input type="number" class="form-control box" id="inputPhone" placeholder="Phone Number">
      </div>
    </div>


    <div class="form-inline">
      <label class="mr-sm-2">Bio</label>
      <div class="circle">i</div>

      <label for="inputBio" class="mr-sm-2"></label>
      <div class="col">
        <textarea class="form-control bio-text" id="inputBio" rows="3" placeholder="Your Bio"></textarea>
      </div>
    </div>
   </form>
 </div>

CSS代码

.form-container { max-width: 449px }
.box { margin-left: 82px }

.bio-text { height: 91px; margin-left: 28px }

input[type="number"] {border: 2px solid #b1b1b1; padding: .55rem .75rem}
textarea {border: 2px solid #b1b1b1; padding: .55rem .75rem}

.circle { width: 22px; height: 22px; border-radius: 50%; color: white;
       line-height: 20px; text-align: center; background: rgb(162, 197, 252); margin-left: 50px}

任何帮助将不胜感激。由于我是网络新手，而且是bootstrap4的新手，因此请视我为学习者。谢谢

最佳答案

对布局进行了一些小的更改。似乎输出是您需要的。 :)

.form-container { max-width: 449px }
.box { margin-left: 82px }

.bio-text { height: 91px; margin-left: 85px;}

input[type="number"] {border: 2px solid #b1b1b1; padding: .55rem .75rem}
textarea {border: 2px solid #b1b1b1; padding: .55rem .75rem}

.circle { width: 22px; height: 22px; border-radius: 50%; color: white;
           line-height: 20px; text-align: center; background: rgb(162, 197, 252); }
