Question

如何让导航项目的背景完全被颜色填充，而不仅仅是其中的一部分？

这是我尝试使用Bootstrap药丸，但它不能完成这项工作。另外，我尝试了自己的CSS，但它和药丸一样。

总而言之，如何仅使用导航项CSS的背景颜色，使我的导航栏（图像中的）看起来像this one。

更新：添加了HTML和CSS代码

我的代码： HTML

            <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
            </button>

            <a class="navbar-brand" href="#"><i class="fa fa-paw" aria-hidden="true"></i> Purrfection Shop</a>



            <!--<i class="fa fa-home" aria-hidden="true"></i>
            <i class="fa fa-sign-in" aria-hidden="true"></i>
            <i class="fa fa-sign-out" aria-hidden="true"></i>-->


            <div class="collapse navbar-collapse" id="navbarSupportedContent">
                <ul class="navbar-nav mr-auto nav-pills">
                    <li class="nav-item">
                        <a class="nav-link" href="#jumbotron">Home</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#services">Services</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#about-container">About</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#footer">Contact</a>
                    </li>
                </ul>
                <ul class="navbar-nav ml-auto nav-pills">
                    <li class="nav-item">
                        <a class="nav-link" href="#!"><i class="fa fa-user-plus" aria-hidden="true"></i> Sign Up</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#!"><i class="fa fa-user" aria-hidden="true"></i> Login</a>
                    </li>
                </ul>
            </div>

    </nav>

CSS：

.navbar {

            border-bottom: 1px solid #F5F5F5;
            background-color: white;
            text-transform: uppercase;
            letter-spacing: 2px;

        }

关键是从导航栏中删除顶部和底部填充，并将其添加到药丸中，从药丸中移除圆角，然后将自定义cssin包装在媒体查询中以使其响应。
