<div class="container">
    <div class="row">
        <div class="col-6">
            <div class="row">
                <div class="col-6">
                    <label>Name</label>
                    <input type="text" class="form-control" />
                </div>
                <div class="col-6">
                    <label>Name</label>
                    <input type="text" class="form-control" />
                </div>
            </div>
        </div>
        <div class="col-6"></div>
    </div>
</div>

一种高级方式：

<div class="container bg-primary" style="width: 800px; height: 100px; ">
    <div class="row ml-1 h-100">
        <div class="col-10 ml-0 my-auto h-75 container bg-danger">
            <div class="row ml-1 h-100">
                <div class="col-8 ml-0 my-auto h-75 container bg-warning">
                    <div class="row ml-1 h-100">
                        <div class="col-6 ml-0 my-auto h-75 container bg-success">
                            <div class="row ml-1 h-100">
                                <div class="col-4 ml-0 my-auto h-75 container bg-dark">

                                </div>
                            </div>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
