网格系统无法在移动设备或小屏幕上正确调整大小

标签： html css twitter-bootstrap twitter-bootstrap-3 bootstrap-4

命令col-xs-whatever不起作用，并在移动视图或小屏幕上创建断行。

注意：我还测试了类.col-作为Bootstrap 4在文档中指定但它仍然不起作用。

它没有正确调整大小并堆积，这是相关代码：

.navbar{
    background-image: cornflowerblue;
}
#mainNav{
    border: 5px solid black;
    margin: 3%;
    background-color: white;
}
body{
    background-color: grey;
}
#navContent{
    background-color: white;
    margin: 3%;
}
#final{
    border: 5px solid black;
    margin: 3%;
    background-color: white;
}
#searchFormContent{
    margin: auto;
    width: 80%;
}
#navToggler{
    float: right;
}
.navbar-toggler{
    float:right;
}

我不知道这是否是你想要的结果，因为你没有指明。

我已将col-xs-whatever更改为col-whatever，之后您将row上的边距和边框应用于#mainNav，这就是为什么所有列都无法放入内部的原因。

因此，我将row移到了包装导航栏中，并从row

中删除了#mainNav

以下是更改的代码：

.navbar{
    background-image: cornflowerblue;
}
#mainNav{
    border: 5px solid black;
    margin: 3%;
    background-color: white;
}
body{
    background-color: grey;
}
#navContent{
    background-color: white;
    margin: 3%;
}
#final{
    border: 5px solid black;
    margin: 3%;
    background-color: white;
}
#searchFormContent{
    margin: auto;
    width: 80%;
}
#navToggler{
    float: right;
}
.navbar-toggler{
    float:right;
}

根据iamwtk的建议，问题的一部分是你必须使用col-XYZ代替col-xs-XYZ，但最大的问题是网格的内容：Brand和Busqueda都超过了col，打破行...尝试播放一点col分配并改变＆＃34; searchFormContent＆＃34;的宽度。让它变得动态;）
