如何創建:切換開關
學習如何使用 CSS 創建“切換開關”(開/關按鈕)。
如何創建切換開關
第一步 - 添加 HTML:
<!-- 矩形開關 --> <label class="switch"> <input type="checkbox"> <span class="slider"></span> </label> <!-- 圓角開關 --> <label class="switch"> <input type="checkbox"> <span class="slider round"></span> </label>
第二步 - 添加 CSS:
/* 開關 - 滑塊周圍的框 */ .switch { position: relative; display: inline-block; width: 60px; height: 34px; } /* 隱藏默認 HTML 復選框 */ .switch input { opacity: 0; width: 0; height: 0; } /* 滑塊 */ .slider { position: absolute; cursor: pointer; top: 0; left: 0; right: 0; bottom: 0; background-color: #ccc; -webkit-transition: .4s; transition: .4s; } .slider:before { position: absolute; content: ""; height: 26px; width: 26px; left: 4px; bottom: 4px; background-color: white; -webkit-transition: .4s; transition: .4s; } input:checked + .slider { background-color: #2196F3; } input:focus + .slider { box-shadow: 0 0 1px #2196F3; } input:checked + .slider:before { -webkit-transform: translateX(26px); -ms-transform: translateX(26px); transform: translateX(26px); } /* 圓角滑塊 */ .slider.round { border-radius: 34px; } .slider.round:before { border-radius: 50%; }
