3D Orange Switch

CSS3 11.10.2021

Ультра-реалистичное применение в CSS. Обратите внимание на тонкое движение и глубину за тумблером, когда он скользит.

Я уже публиковал уроки «Замена стандартного checkbox по средствам CSS3» и «CSS стилизация checkbox и radio».

В данном примере, как и в тех, используется только CSS.

HTML:

<label class="switch">
  <input type="checkbox" checked/>
  <div class="indicator left"></div>
  <div class="indicator right"></div>
  <div class="button"></div>
</label>

CSS:


body, html {
  width: 100vw;
  height: 100vh;
}

body {
  background-image: linear-gradient(135deg, hsl(var(--hue) 20% 95%), hsl(var(--hue) 20% 80%));
  display: flex;
  align-items: center;
  justify-content: center;
  --hue: 220deg;
  --width: 8rem;
  --accent-hue: 22deg;
  --duration: 0.6s;
  --easing: cubic-bezier(1, 0, 1, 1);
}

input {
  display: none;
