Need help in making centered form-CodePudding

I am noob here, learning new things. I am trying to make this center form.

This is what I have tried so far :-

<!doctype html>
<html lang="en">

<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>Bootstrap demo</title>
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-0evHe/X R7YkIZDRvuzKMRqM OrBnVFBL6DOitfPri4tjfHxaWutUpFmBp4vmVor" crossorigin="anonymous">

  <style>
    .container {
      height: 100%;
      width: 50%
    }
    
    .center-block {
      margin: auto;
      display: block;
    }
  </style>

</head>

<body>
  <div >
    <h1 >CARD NUMBER CHECKER</h1>
    <br>
    <br>


    <div >
      <div >
        <div >
          <label >Input Number</label>
        </div>
        <div >
          <input type="text" >
        </div>
      </div>
    </div>
    <br>
    <div >
      <button  type="button">Submit</button>
    </div>
  </div>
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-pprn3073KE6tl6bjs2QrFaJGz5/SUsLqktiwsUTF55Jfv3qYSDhgCecCxMW52nD2" crossorigin="anonymous"></script>
</body>

</html>

CodePudding user response：

Bootstrap 5 has classes that can do all of that for you as opposed to adding other CSS:

https://getbootstrap.com/docs/5.0/utilities/flex/

https://getbootstrap.com/docs/5.0/utilities/spacing/

d-flex sets the container div to a flexbox, flex-column sets the direction of the box to a column, align-items-center aligns everything to the horizontal center, and gap-4 gives you some spacing between all elements. You could even remove the input container all together unless you specifically need it for something else.

h1 {
  font-family: Georgia, "Times New Roman", Times, serif;
}
