如何创建:切换开关
学习如何使用 CSS 创建“切换开关”(开/关按钮)。
如何创建切换开关
第一步 - 添加 HTML:
<!-- 矩形开关 --> <label class="switch"> <input type="checkbox"> <span class="slider"></span> </label> <!-- 圆角开关 --> <label class="switch"> <input type="checkbox"> <span class="slider round"></span> </label>
第二步 - 添加 CSS:
/* 开关 - 滑块周围的框 */
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}
/* 隐藏默认 HTML 复选框 */
.switch input {
opacity: 0;
width: 0;
height: 0;
}
/* 滑块 */
.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);
}
/* 圆角滑块 */
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;
}
