我正在使用 Bootstrap v3。在使用 col-xs-12 的移动设备中,div 不会占据 100% 的宽度。代码在中小屏幕上运行良好,但在小于 768 的屏幕上保留了 50% 的宽度。这里是行为截图的链接。 Image
尝试了所有其他可用的解决方案,但没有一个对我有用。
我不知道如何用语言表达,但我在调整浏览器窗口大小时获得了所需的输出,但代码似乎无法在实际设备和网络检查器上运行。设备截图Image
此外,我在 css 末尾也尝试了 !important,但遇到了同样的问题。

摘自 chetan kalra 的评论并发布答案以供其他人快速引用。我也遇到了这个问题,发现视口(viewport)元标记丢失了。添加下面一行就可以了。
<meta name="viewport" content="width=device-width, initial-scale=1.0">
关于html - col-xs 不适用于小于 768px 的媒体屏幕,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/44230996/
