Bootstrap Form Controls

Bootstrap form controls give textual form controls like <input> and <textarea> an upgrade with custom styles, sizing, focus states, and more.

You have to add class .form-label on labels and .form-control on input and textarea elements.

For example,

<div class="mb-3">
 <label for="exampleFormControlInput1" class="form-label">Email address</label>
 <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com">
</div>
<div class="mb-3">
 <label for="exampleFormControlTextarea1" class="form-label">Example textarea</label>
 <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
</div>

1. Sizing

You can set heights using classes like .form-control-lg and .form-control-sm.

2. Disabled

Add the disabled boolean attribute on an input to give it a grayed out appearance and remove pointer events.

3. Readonly

Add the readonly boolean attribute on an input to prevent modification of the input’s value. Read-only inputs appear lighter (just like disabled inputs), but retain the standard cursor.

4. Readonly plain text

If you want to have elements in your form styled as plain text, use the .form-control-plaintext class to remove the default form field styling and preserve the correct margin and padding.
