代码解读
定义 dom,容器中包含 2 个元素:
<div class="ice-lolly">
<div class="flavors"></div>
<div class="stick"></div>
</div>
居中显示:
body {
margin: 0;
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
background-color: darkslategray;
}
绘制出冰棍的外形:
.flavors {
width: 19em;
height: 26em;
font-size: 10px;
border-radius: 8em 8em 1em 1em;
}
给冰棍上色:
.flavors {
position: relative;
overflow: hidden;
}
.flavors::before {
content: '';
position: absolute;
width: 140%;
height: 120%;
background: linear-gradient(
hotpink 0%,
hotpink 25%,
deepskyblue 25%,
deepskyblue 50%,
gold 50%,
gold 75%,
lightgreen 75%,
lightgreen 100%);
z-index: -1;
left: -20%;
transform: rotate(-25deg);
}
来一点光照效果:
.flavors::after {
content: '';
position: absolute;
width: 2em;
height: 17em;
background-color: rgba(255, 255, 255, 0.5);
left: 2em;
bottom: 2em;
border-radius: 1em;
}
画出冰棍筷子:
.stick {
position: relative;
width: 6em;
height: 8em;
background-color: sandybrown;
left: calc(50% - 6em / 2);
border-radius: 0 0 3em 3em;
}
给冰棍筷子加一点阴影,增加立体感:
.stick::after {
content: '';
position: absolute;
width: inherit;
height: 2.5em;
background-color: sienna;
}
让冰棍的色彩滚动起来:
.flavors::before {
animation: moving 100s linear infinite;
}
@keyframes moving {
to {
background-position: 0 1000vh;
}
}
最后,增加交互效果,当鼠标悬停时才播放动画:
.flavors::before {
animation-play-state: paused;
}
.ice-lolly:hover .flavors::before {
animation-play-state: running;
}
大功告成!
