Question

我试图修改我的导航栏跨媒体查询，对于中型和大型屏幕，我的徽标是一个jumbotron div，但我想改变屏幕小于768px时出现的位置，我想放它在我的导航栏上。我可以在我的CSS上制作它。

感谢名单。

这是我的md和lg屏幕代码。

                        <li class="icon"><a href="#"><img src="img/iconos/tube-icon.png" alt=""></a></li>           
                    </ul>

        </div>
    </div><!-- /.navbar-collapse -->
</nav>

Answer 1

如果您想使用CSS3为不同的屏幕宽度设计不同的布局，请使用media queries。

为了实现您的要求，请考虑默认情况下隐藏Jumbotron中的徽标，并仅在屏幕的最小宽度超过一定量时显示该徽标。例如，您的CSS可能如下所示：

.my-logo {
    display: none;
}

@media (min-width: 992px) {
    .my-logo {
        display: block;
    }
}

然后，您可以使用相同的逻辑来显示/隐藏导航栏中的徽标。
