代码解读

定义容器 halloween-switcher , 通过 checkbox 来实现切换

<section class="halloween-switcher">
 <input type="checkbox" id="halloween-input">
 <label for="switch-input" class="halloween-label">
 <div class="pumpkin-container"></div>
 <div class="vampire-container"></div>
 </label>
</section>

引入字体, 居中显示:

@import url('https://fonts.googleapis.com/css?family=Kodchasan');

* {
 font-family: 'Kodchasan';
}

html {
 font-size: 20px;
}

body {
 width: 100vw;
 height: 100vh;
 display: flex;
 align-items: center;
 justify-content: center;
 background: #081219;
 overflow: hidden;
}

设置实际容器 label 大小

.halloween-label {
 width: 30rem;
 height: 10rem;
 border: 3px solid #E56D48;
 border-radius: 10rem;
 cursor: pointer;
 display: flex;
 align-items: center;
 position: relative;
}

增加两种容器的配色

html {
 --pumpkin-color: #E56D48;
 --vampire-color: #4D7C99;
}

定义 pumpkin-container , vampire-container 容器及文字

.halloween-input ~ .halloween-label::before,
.halloween-input:checked ~ .halloween-label::before {
 position: absolute;
 font-size: 2.5rem;
 text-transform: uppercase;
}
.halloween-input ~ .halloween-label::before {
 content: 'Pumpkin';
 color: var(--pumpkin-color);
 left: 70%;
 transform: translateX(-70%);
}
.halloween-input:checked ~ .halloween-label::before {
 content: 'Vampire';
 color: var(--vampire-color);
 left: 25%;
 transform: translateX(-25%);
}

.halloween-input ~ .halloween-label .pumpkin-container,
.halloween-input ~ .halloween-label .vampire-container {
 width: 9.5rem;
 height: 9.5rem;
 border-radius: 50%;
 position: absolute;
 left: 0.25rem;
 overflow: hidden;
}
.halloween-input ~ .halloween-label .pumpkin-container {
 background-color: var(--pumpkin-color);
 filter: opacity(1);
}
.halloween-input ~ .halloween-label .vampire-container {
 background-color: var(--vampire-color);
 filter: opacity(0);
}
.halloween-input:checked ~ .halloween-label .pumpkin-container {
 left: calc(100% - 0.25rem);
 transform: translateX(-100%);
 filter: opacity(0);
}
.halloween-input:checked ~ .halloween-label .vampire-container {
 left: calc(100% - 0.25rem);
 transform: translateX(-100%);
 filter: opacity(1);
}

增加 label容器颜色渐变

 border: 3px solid var(--label-border-color);
 transition: .5s ease-in-out;
}
