划分Bootstrap网格列的最佳方法

Question

我按照下面的方式划分了Bootstrap网格列.

<div class="container-fluid">
    <div class="row">
        <div class="col-md-3">A</div>
        <div class="col-md-6">
            <div class="col-md-12">B1</div>
            <div class="col-md-12">
                <div class="col-md-8">B1.1</div>
                <div class="col-md-4">B1.2</div>
            </div>
            <div class="col-md-12">
                <div class="col-md-10">B2.1</div>
                <div class="col-md-2">B2.2</div>
            </div>
        </div>
        <div class="col-md-3">C</div>
    </div>
</div>

请在下面找到此代码的可视布局.

我划分网格列的方法是正确还是错误？

Answer 1

始终将列包装在一行中,以避免在调整大小/或类似内容时出现任何css中断

<div class="container-fluid">
    <div class="row">
        <div class="col-md-3">A </div>

        <div class="col-md-6">B
            <div class="row">
                <div class="col-md-12">B1</div>
            </div>
            <div class="row">
                <div class="col-md-8">B1.1</div>
                <div class="col-md-4">B1.2</div>
            </div>
            <div class="row">
                <div class="col-md-10">B2.1</div>
                <div class="col-md-2">B2.2</div>
            </div>
        </div>

        <div class="col-md-3">C </div>
    </div>
</div>

Answer 2

你应该为B里面的孩子添加行div.

<div class="container-fluid">

    <div class="row">
        <div class="col-md-3">
        A
        </div>


        <div class="col-md-6">
            <div class="row">
                <div class="col-md-12">B1</div>
            </div>

            <div class="row">
                <div class="col-md-8">B1.1</div>
                <div class="col-md-4">B1.2</div>
            </div>

            <div class="row">
                <div class="col-md-10">B2.1</div>
                <div class="col-md-2">B2.2</div>
            </div>
        </div>

        <div class="col-md-3">
        C
        </div>
    </div>

</div>
