问题描述

I have a Bootstrap Navigation bar, I want to change the color of the links in the navigation bar, on hover.我有一个引导导航栏，我想在悬停时更改导航栏中链接的颜色。 I have tried CSS for it but it is not working.我已经为此尝试了 CSS，但它不起作用。 I don't want to change the code, but within the same tag classes I want to add the effect.我不想更改代码，但在相同的标记类中我想添加效果。 Some people use lists for the navigation bar, I don't want to do so.有些人使用列表作为导航栏，我不想这样做。

I have tried to add CSS for the same for the hover with class defined in the each tag.我试图为悬停添加相同的 CSS，并在每个标签中定义类。

Add below CSS for adding hover to navigation and add after bootstrap CSS in header 在CSS下方添加用于向导航添加悬停的代码，并在标头中引导CSS之后添加 

.navbar-dark .navbar-nav .nav-link.services-link:hover {
  color: rgba(0,255,0,1);
}

if you want it specifically on service, add an id to the Services <a class="nav-item nav-link services-link" id="services-link" href="#"><strong>Services</strong></a> 如果您要专门用于服务，请将ID添加到服务<a class="nav-item nav-link services-link" id="services-link" href="#"><strong>Services</strong></a>

and then in your css file add this 然后在您的css文件中添加此 

#services-link:hover {
color: green;
}
