我有两个不同的部分具有完全相同的CSS代码但是如果你看下面的图像，你可以看到屏幕设置的宽度，图像都已经移动到一个新的行（这是什么我想）但是下面的类别仍然在同一条线上并得到更多＆＃34;压扁＆＃34;一起。我怎样才能使类别移动到像图像那样的新线？提前谢谢。

答案 0 :(得分：0)
问题是您的类别div设置为width：20％with display：inline-block导致它们保留在列中。首先，如果您希望它们堆叠在一起，您可以将宽度更改为100％和/或显示为阻止：
.categories{
display: block;
width: 100%;
}
这将影响桌面设计，因此，如果您正在响应地构建此设计，则实际上只需添加：
@media only screen and (max-width: 568px) {
.categories{
display: block;
width: 100%;
}
}
