Example
Use form-control in combination with type to style input elements and form-label to style the corresponding labels
<div>
<label for="exampleFormControlInput1" class="form-label">Email address</label>
<input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com" />
</div>
<div>
<label for="exampleFormControlTextarea1" class="form-label">Example textarea</label>
<textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
</div>
Sizing
Set heights using classes like form-control-lg and form-control-sm
<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg" aria-label=".form-control-lg example" />
<input class="form-control" type="text" placeholder="Default input" aria-label="default input example" />
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm" aria-label=".form-control-sm example" />
Disabled
Add the disabled boolean attribute on an input to give it a grayed out appearance and remove pointer events.
<input class="form-control" type="text" placeholder="Disabled input" aria-label="Disabled input example" disabled />
<input class="form-control" type="text" value="Disabled readonly input" aria-label="Disabled input example" disabled readonly />
Readonly
Add the readonly boolean attribute on an input to prevent modification of the input’s value.
<input class="form-control" type="text" value="Readonly input here..." aria-label="readonly input example" readonly />
Readonly plain text
If you want to have <input readonly> 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. Note how we use the .col-form-label class to center the label vertically.
<div class="flex">
<label for="staticEmail" class="mr-6 col-form-label">Email</label>
<input type="text" readonly class="form-control-plaintext" id="staticEmail" value="email@example.com">
</div>
File input

<label for="formFile" class="form-label">Default file input example</label>
<input class="form-control" type="file" id="formFile" />

<input class="form-control" type="file" id="formFileMultiple" multiple />

Datalists
Datalists allow you to create a group of <option>s that can be accessed (and autocompleted) from within an <input>. These are similar to <select> elements, but come with more menu styling limitations and differences. While most browsers and operating systems include some support for <datalist> elements, their styling is inconsistent at best.
<label for="exampleDataList" class="form-label">Datalist example</label>
<input class="form-control" list="datalistOptions" id="exampleDataList" placeholder="Type to search..." />
<datalist id="datalistOptions">
<option value="San Francisco"></option>
<option value="New York"></option>
<option value="Seattle"></option>
<option value="Los Angeles"></option>
<option value="Chicago"></option>
</datalist>
