我尝试使用css对我的简历进行更改，但这些更改并未适用。我尝试在Brackets代码编辑器中使用Live Preview并使用firefox直接打开文件。我已将样式表链接到我的html文档。这是我的css：

我的问题是font-size: 20px;断点中的@media (min-width : 1200px)等更改无法正常工作。我没有看到文件中的任何变化。我尝试在断点处将最小宽度更改为最大宽度，但这没有做任何事情。我还认为断点本身可能不起作用，所以我将body标签放在顶部以适用于所有尺寸，但仍然没有。我只是得到通用的font-size = 14px;这是bootstrap的标准。有什么想法吗？

您应该始终在（下面）bootstrap css链接之后链接您的自定义样式表。
