我尝试了很多可能的方法来添加我的CSS，即使在内联样式也没有用。是我的铬问题吗？在我的另一个项目中我如何设计我的HTML工作正常。但在这。我甚至没有把CSS添加到锚中。我知道这很简单，但它对我不起作用。即使在悬停。它不会更改默认事件。

Answer 1

打开开发人员工具，右键单击刷新，左键单击清除缓存并重新加载。

Answer 2

看起来您遗漏了对Bootstrap CSS和JavaScript的引用。您可能还需要在浏览器中进行“硬”刷新（Chrome中的 Ctrl + Shift + R ）。试试这些，它应该按预期工作。

此外，不确定您是否只是在测试，但a:link伪选择器无效的原因是由于您在样式表中使用的!important规则。
