Standard Form Layout
To create Bootstrap form layout, you just have to add form-control class to each input, and wrap label & input inside a form-group class div.
Here is a basic example:
<form role="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="password">Password</label>
<input type="password" class="form-control" id="password">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
Horizontal Form Layout
If you prefer to have label & input on the same line, just add form-horizontal class to your form.
Here is an example:
<form role="form" class="form-horizontal"> <!-- YOUR FORM CONTENT --> </form>
