Bootstrap 3에서 입력 필드 너비를 관리하는 방법은 무엇입니까?

<code class="html"><div class="container">
    <form role="form">
        <div class="row">
            <div class="form-group col-lg-1">
                <label for="code">Name</label>
                <input type="text" class="form-control">
            </div>
        </div>

        <div class="row">
            <div class="form-group col-lg-1">
                <label for="code">Email</label>
                <input type="text" class="form-control input-normal">
            </div>
        </div>

        <div class="row">
            <button type="submit" class="btn btn-default">Submit</button>
        </div>
    </form>
</div></code>
