Question

我有一个带有引导CSS的网站。

我在chrome和Edge浏览器上对其进行了测试，CSS看起来非常不错。

在firefox上，一切看起来都放大了。当我进入浏览器的设置并缩小时，我可以看到完整的HTML。

在chrome上：

Firefox正常大小：

Firefox缩小了：

我对CSS完全陌生，将不胜感激。

Answer 1

@HelpASisterOut，您应该真正重新考虑HTML和CSS格式。该网站不必这么复杂。常规样式建议如下：

避免在CSS中将样式设置为html / body / div / span标签
避免重复使用CSS代码，而应使用类（填充，边距等）
避免使用calc（）以及百分比和像素的混合使用（破坏页面的响应能力）
考虑另一种解决方案（继承，类，id），而不是在各处使用！important
避免使用溢出并手动设置位置，因为每个浏览器可能呈现不同的内容/大小

诸如重复相同宽度的引导程序类之类的其他事情是不必要的：

col-sm-9 col-xs-9

bootstrap采用较小的靴子，并适用于所有较大的靴子。

这不是直接的答案，对于没有指出确切的错误，我深表歉意，但是我向您保证，考虑到这一点，您的应用程序将正确显示在所有市长浏览器甚至移动设备上。您只需要以不同的方式看待事情，也许可以浏览其他人制作的某些网页。希望这可以帮助。很好的学习！
