Bootstrap CSS Forms Reference
Bootstrap's Default Settings
Individual form controls automatically receive some global styling with Bootstrap.
All textual <input>, <textarea>, and <select> elements with class="form-control" are set to width: 100%; by default.
Standard rules for all three form layouts:
- Wrap labels and form controls in
<div class="form-group">(needed for optimum spacing) - Add class
.form-controlto all textual<input>,<textarea>, and<select>elements
The following example creates a simple Bootstrap form with two input fields, one checkbox, and a submit button:
Bootstrap Form Example
<form>
<div class="form-group">
<label for="email">Email address:</label>
<input type="email" class="form-control" id="email">
</div>
<div class="form-group">
<label for="pwd">Password:</label>
<input type="password" class="form-control" id="pwd">
</div>
<div class="checkbox">
<label><input type="checkbox"> Remember me</label>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
