Html Bootstrap 3.3.7 md上的列布局问题

这是我的引导网站的当前布局。不幸的是，它不工作，因为列完全关闭了md大小

是当前视图

我的目标是将它们按md大小的2列进行分组。因此，布局将是

图像+文本；新栏目；图像+文本；新栏目；图像+文本

        <div class="row">
            <div class="col-lg-4 col-md-6 coko">

                <h3 class="text-center">Cakes</h3></div></a> 
            </div>
            <div class="col-lg-4 col-md-6 coko">
                <p class="text-center">In 1995, <a href="index.html">The Rolling Pin</a> 
                opened its first location on a quiet street corner in the heart of 
                Munich. From its inception, The Rolling Pin has been cherished for its 
                classic Germany baked goods, vintage decor and warm, invitig atmosphere.

这样的布局有两个挑战

首先，您希望所有元素都位于同一行中，其次，您需要考虑不同高度的列。第n个子选择器和一些@media选择器是操纵CSS并使其工作的有效方法

HTML-这与您的完全相同，只是有几行注释掉了，所以所有元素都在同一行中
