我正在尝试使用上面的图像进行集中输入。我按照位置文档进行操作,但不知何故图像没有水平集中:

<body>
<div class="container position-absolute top-50 start-50 translate-middle">

<form action="/streams" method="POST">
<div class="input-group">
<input class="form-control border-danger border-5" type="text" aria-describedby="start-button">
<button class="btn btn-danger" type="submit" id="start-button">Click</button>
</div>
</form>
</div>
</body>
</html>
我尝试手动执行此操作并使用 display flex,但没有成功。
使用
text-center
