Question

在大型桌面中，四个div应该出现在一行中。在中等大小中，应该出现三个div，在小型设备中，两个div和移动设备中只有一个潜水应该出现在一行中。我实现了它。但是我需要所有的div都有边界，并且在两个连续的div之间应该有一个px间隙。

我添加了边框它工作正常，当我向div添加边距1px然后在大型桌面中第四个div将移动到下一行。我的Html代码是 -

您不应直接对网格元素应用边距，边框等。这需要对Bootsrap的CSS中的大小调整进行相应的调整，这使得维护和更新更具挑战性。

而是将样式应用于网格容器内的元素。

.bordered {
    border:solid 1px black;
}

<div class="col-sm-6 col-md-4 col-lg-3 divCustom">
    <div class="bordered">Personal Information
        <div class="row">
            <div class="col-xs-12">
                <label class="control-label" for="txtName">Name</label>
                <input id="txtName" class="form-control" />
            </div>
       ...

根据您的偏好调整.bordered上的边距。您可以使用负边距延伸到网格元素之外并获得您提到的1px间隙（或者可能是2px，因为它更容易）。
