悬停时更改引导导航栏链接的颜色

时间：2019-06-25 04:55:06

标签： html css bootstrap-4

我有一个Bootstrap导航栏，我想在悬停时更改导航栏中链接的颜色。我已经尝试过CSS，但无法正常工作。 我不想更改代码，但是我想在相同的标记类中添加效果。某些人在导航栏中使用列表，我不想这样做。

我尝试为每个标签中定义的类的悬停添加相同的CSS。

                            <a class="nav-item active nav-link contact-link" href="Contact Us.html"><strong>Contact Us</strong></a>

                </nav>
            </div>
        </body>
        </html>

当我将鼠标悬停在服务上时，我希望它具有绿色。

在 CSS 下添加，用于将悬停添加到导航中，并在 bootstrap CSS 后添加到标题中

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

如果要在服务中专门使用它，请在服务中添加一个ID <a class="nav-item nav-link services-link" id="services-link" href="#"><strong>Services</strong></a>

然后在您的css文件中添加此

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