使用纯CSS实现圆形导航菜单效果（代码示例）

body { background-color: #262626 } .demo { padding: 2em 0; transform: translate3d(0, 0, 0); } .navbar { width: 150px; height: 150px; line-height: 150px; border-radius: 50%; background: #fff; margin: 70px auto; position: relative; cursor: pointer; text-align: center; font-size: 1.75em; font-weight: bold; color: #383838; transition: 0.24s 0.2s; } .navbar:hover { background: rgba(255, 255, 255, 0.75); } .navbar .menu { list-style: none; padding: 0; margin: 0; position: absolute; top: -75px; left: -75px; border: 150px solid transparent; cursor: default; border-radius: 50%; transform: scale(0); transition: transform 1.4s 0.07s; z-index: -1; } .navbar:hover .menu { transition: transform 0.4s 0.08s, z-index 0s 0.5s; transform: scale(1); z-index: 1; } .navbar .menu li { position: absolute; top: -100px; left: -100px; transform-origin: 100px 100px; transition: all 0.5s 0.1s; } .navbar:hover .menu li { transition: all 0.6s; } .navbar .menu li a { transition:all .4s ease 0s; width: 45px; height: 45px; line-height: 45px; border-radius: 50%; background: #fff; position: absolute; font-size: 60%; color: #99b977; transition: 0.6s; text-decoration: none; } .navbar .menu li a:hover { background-color: #2860F8; color: #fff; } .navbar:hover .menu li:nth-child(1) { transition-delay: 0.02s; transform: rotate(85deg); } .navbar:hover .menu li:nth-child(1) a { transition-delay: 0.04s; transform: rotate(635deg); } .navbar:hover .menu li:nth-child(2) { transition-delay: 0.04s; transform: rotate(125deg); } .navbar:hover .menu li:nth-child(2) a { transition-delay: 0.08s; transform: rotate(595deg); } .navbar:hover .menu li:nth-child(3) { transition-delay: 0.06s; transform: rotate(165deg); } .navbar:hover .menu li:nth-child(3) a { transition-delay: 0.12s; transform: rotate(555deg); } .navbar:hover .menu li:nth-child(4) { transition-delay: 0.08s; transform: rotate(205deg); } .navbar:hover .menu li:nth-child(4) a { transition-delay: 0.16s; transform: rotate(515deg); } .navbar:hover .menu li:nth-child(5) { transition-delay: 0.1s; transform: rotate(245deg); } .navbar:hover .menu li:nth-child(5) a { transition-delay: 0.2s; transform: rotate(475deg); } .navbar:hover .menu li:nth-child(6) { transition-delay: 0.12s; transform: rotate(285deg); } .navbar:hover .menu li:nth-child(6) a { transition-delay: 0.24s; transform: rotate(435deg); } .navbar:hover .menu li:nth-child(7) { transition-delay: 0.14s; transform: rotate(325deg); } .navbar:hover .menu li:nth-child(7) a { transition-delay: 0.28s; transform: rotate(395deg); } .navbar:hover .menu li:nth-child(8) { transition-delay: 0.16s; transform: rotate(365deg); } .navbar:hover .menu li:nth-child(8) a { transition-delay: 0.32s; transform: rotate(355deg); } .navbar:hover .menu li:nth-child(9) { transition-delay: 0.18s; transform: rotate(405deg); } .navbar:hover .menu li:nth-child(9) a { transition-delay: 0.36s; transform: rotate(315deg); }
