A bootstrap is a popular tool for creating web pages and websites. It's a great resource because it provides a lot of predesigned components, colors, and layouts to make the process of designing websites much easier for designers. This article shows how to create a registration form with Bootstrap using source code.

Copy-paste the stylesheet <link> into your <head> before all other stylesheets to load our CSS.

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.1/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-F3w7mX95PdgyTmZZMECAngseQB83DfGTowi0iMjiWaeVhAn4FJkqJByhZMI3AhiU" crossorigin="anonymous">

Also, add bootstrap icons CSS below the bootstrap CSS

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap-icons@1.5.0/font/bootstrap-icons.css">

Add the following stylesheet to set page background and rounded buttons in the head tag.

<style>
      .bg-color{
          background-color: #f9fbfd;
          font-family: Arial, Helvetica, sans-serif;
      }
      .btn-rounded{
          border-radius: 30px;
      }
</style>

Use the following code for the Registration form design.

<body class="bg-color">
    <section class="container mt-5">
        <div class="row justify-content-md-center">
