Individual form controls receive styling, but without any required base class on the <form> or large changes in markup. Results in stacked, left-aligned labels on top of form controls.
<form>
<fieldset>
<legend>Legend</legend>
<label>Label name</label>
<input type="text" placeholder="Type something…">
<span class="help-block">Example block-level help text here.</span>
<label class="checkbox">
<input type="checkbox"> Check me out
</label>
<button type="submit" class="btn">Submit</button>
</fieldset>

<form class="form-search"> <input type="text" class="input-medium search-query"> <button type="submit" class="btn">Search</button> </form>
Add .form-inline for left-aligned labels and inline-block controls for a compact layout.
<form class="form-inline">
<input type="text" class="input-small" placeholder="Email">
<input type="password" class="input-small" placeholder="Password">
<label class="checkbox">
<input type="checkbox"> Remember me
</label>
<button type="submit" class="btn">Sign in</button>
</form>
Right align labels and float them to the left to make them appear on the same line as controls. Requires the most markup changes from a default form:
<form class="form-horizontal">
<div class="control-group">
<label class="control-label" for="inputEmail">Email</label>
<div class="controls">
<input type="text" id="inputEmail" placeholder="Email">

</div>
<div class="control-group">
<label class="control-label" for="inputPassword">Password</label>
<div class="controls">
<input type="password" id="inputPassword" placeholder="Password">
</div>
</div>
<div class="control-group">
<div class="controls">
<label class="checkbox">
<input type="checkbox"> Remember me
</label>
<button type="submit" class="btn">Sign in</button>
</div>
