How to change navbar hover color on bootstrap 4?
提问by Berglund
I need to change my navbar hover color to something else. I managed to change navbar text color on my own, but I couldn't find the correct one to change in inspect element for hover color.
我需要将导航栏悬停颜色更改为其他颜色。我设法自己更改导航栏文本颜色，但我找不到正确的颜色来更改检查元素的悬停颜色。
Then I looked it up on stackoverflow for previous asnwers but they didn't work for my code. Any input would be greatly appreciated!
然后我在stackoverflow上查找以前的asnwers，但它们对我的代码不起作用。任何投入将不胜感激！

Bootstrap has default color for < a> tag. So by using !important you over write the color
Bootstrap 具有 <a> 标签的默认颜色。所以通过使用 !important 你覆盖了颜色
