我目前正在使用css设计hero slider的导航按钮,下面是我的代码,不过我想在www.bbc.co.uk上实现类似于slider的按钮。展开div并显示文本。谁能告诉我怎么做

这是我想要编辑的按钮的css

.hero-carousel-nav li {
            position: absolute;
            bottom: 48px;
            right: 48px;
            list-style: none;
            }

        .hero-carousel-nav li.prev {
            left: 48px;
            right: auto;
            }

        .hero-carousel-nav li a {
            background: #FFF;
            color: #fff;
            border: none;
            outline: none;
            display: block;
