如何管理引导 4 网格？

Question

实际上，我有两个侧面，例如col-md-6和col-md-6 ，并且我在左侧和右侧有六个images ，我只需要一个images ，如下面的代码所示。

这工作正常，但是当右侧图像不可用时，我需要将左六列扩展为全宽。 我该怎么办？

 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script> <div class="container"> <div class="row"> <div class="col-6"> <div class="row"> <div class="col-4" style="background-color:yellow;">img</div> <div class="col-4" style="background-color:orange;">img</div> <div class="col-4" style="background-color:blue;">img</div> <div class="col-4" style="background-color:red;">img</div> <div class="col-4" style="background-color:lime;">img</div> <div class="col-4" style="background-color:indianred;">img</div> </div> </div> <div class="col-6 p-0"> <div class="col-12" style="background-color:green; height:48px;">img</div> </div> </div> </div>

如果正确col-md-6不可用，我想要如下代码所示：-

 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script> <div class="container"> <div class="row"> <div class="col-12"> <div class="row"> <div class="col-2" style="background-color:yellow;">img</div> <div class="col-2" style="background-color:orange;">img</div> <div class="col-2" style="background-color:blue;">img</div> <div class="col-2" style="background-color:red;">img</div> <div class="col-2" style="background-color:lime;">img</div> <div class="col-2" style="background-color:indianred;">img</div> </div> </div> </div> </div>

答案将不胜感激！
