I have a form that looks like this:

Removing the mb-3 class does nothing to help, it just removes the spaces between the inputs. How am I supposed to ensure the button stays within the blue box?

<form action="/user/loginattempt" class="p-3 rounded-4" style="background-color:rgb(192, 242, 255);" method="POST">
  <div class="mb-3">
    <label for="username" class="form-label">Username</label>
    <input type="text" class="form-control" id="username" name="username" placeholder="Username" />
  </div>
  <div class="mb-3">

  </div>
  <button type="submit" class="btn btn-success float-end">Hop In</button>
</form>

The issue is caused by using float-end on the button which will move the button out of the normal flow and float it.
Simply use Flexbox with flex-direction: column on the container by adding the classes d-flex and flex-column.
After that you can push the button to the right side by adding the class ms-auto to the button:

<!-- Body -->
<form action="/user/loginattempt" class="p-3 rounded-4 d-flex flex-column" style="background-color:rgb(192, 242, 255);" method="POST">
  <div class="mb-3">
    <label for="username" class="form-label">Username</label>
    <input type="text" class="form-control" id="username" name="username" placeholder="Username" />
  </div>
  <div class="mb-3">
    <label for="password" class="form-label">Password</label>
    <input type="password" class="form-control" id="password" name="password" placeholder="Password" />
  </div>
  <button type="submit" class="btn btn-success ms-auto">Hop In</button>
</form>

You need to clear the float using clearfix after float. Then it works.

<div class="clearfix"></div>

Or you can write it in CSS:

form::after{
    content: "";
    display: table;
    clear: both;
}

<form action="/user/loginattempt" class="p-3 rounded-4" style="background-color:rgb(192, 242, 255);" method="POST">
    <div class="mb-3">
        <label for="username" class="form-label">Username</label>
        <input type="text" class="form-control" id="username" name="username" placeholder="Username"/>
    </div>
    <div class="mb-3">
        <label for="password" class="form-label">Password</label>
        <input type="password" class="form-control" id="password" name="password" placeholder="Password"/>
    </div>
    <button type="submit" class="btn btn-success float-end">Hop In</button>
    <div class="clearfix"></div>
</form>

The ‘float-end’ class makes the button float to the right, so we need to add 'overflow: hidden;' to the form container to keep it within the blue box

<!-- Body -->
<form action="/user/loginattempt" class="p-3 rounded-4" style="background-color:rgb(192, 242, 255); overflow: hidden;" method="POST">
  <div class="mb-3">
    <label for="username" class="form-label">Username</label>
    <input type="text" class="form-control" id="username" name="username" placeholder="Username" />
  </div>
  <div class="mb-3">
    <label for="password" class="form-label">Password</label>
    <input type="password" class="form-control" id="password" name="password" placeholder="Password" />
  </div>

  <button type="submit" class="btn btn-success float-end">Hop In</button>
</form>

If you want to use float and solve it the bootstrap way, you should give the parent element the class "clearfix". This fixes the "clearfix bug" when you have bootstrap loaded.

Bootstrap 5.2 Documentation: "Clearfix"

I wrapped a container around the form and gave it the class "clearfix".

Since I think it’s unusual to put css styles on the form-tag, I moved the styles from the form-tag to the outer container.

(Usually only the parameters needed for sending are used in a form-tag. Probably to create a more precise separation between styling and functionality. An "official rule" is not known to me at least.)

<div class="p-3 rounded-4 clearfix" style="background-color:rgb(192, 242, 255);">
    <form action="/user/loginattempt" method="POST">
        <div class="mb-3">
            <label for="username" class="form-label">Username</label>
            <input type="text" class="form-control" id="username" name="username" placeholder="Username" />

        <div class="mb-3">

         </div>
         <button type="submit" class="btn btn-success float-end">Hop In</button>
    </form>
</div>

One (Bootstrap) way would be to remove the fload-end class from the button and wrap it inside an element with d-flex and justify-content-end.

<!-- Body -->
<form action="/user/loginattempt" class="p-3 rounded-4" style="background-color:rgb(192, 242, 255);" method="POST">
  <div class="mb-3">
    <label for="username" class="form-label">Username</label>
    <input type="text" class="form-control" id="username" name="username" placeholder="Username" />
  </div>
  <div class="mb-3">
    <label for="password" class="form-label">Password</label>
    <input type="password" class="form-control" id="password" name="password" placeholder="Password" />
  </div>
  <div class="d-flex justify-content-end">
    <button type="submit" class="btn btn-success">Hop In</button>
  </div>
</form>

Another (Bootstrap) way would be to remove the fload-end class and add d-block and ms-auto classes to your button to force a display: block; with an automatic left-margin (margin-left: auto;).

    <label for="username" class="form-label">Username</label>
    <input type="text" class="form-control" id="username" name="username" placeholder="Username" />
  </div>
  <div class="mb-3">
    <label for="password" class="form-label">Password</label>
    <input type="password" class="form-control" id="password" name="password" placeholder="Password" />
  </div>
  <button type="submit" class="btn btn-success d-block ms-auto">Hop In</button>
</form>

Both methods achieve the exact same results.
