css 如何绘制水滴
- 可以通过box-shadow 来显示阴影
- 可以通过border-radius 改变水滴的形状
- 当然如果像要使其更加灵活,可以使用animation+keyframes关键帧+border-radius,让水滴动起来
是不是很简单
来吧展示效果
html代码,就只有一个div,然后使用一些伪类结合
<div class="water-container">
<div class="water"></div>
</div>
css代码
.water-container {
width: 50vw;
height: 50vh;
background-color: #eff0f4;
display: flex;
justify-content: center;
align-items: center;
}
.water {
width: 120px;
height: 120px;
border-radius: 50%;
box-shadow: inset 20px 20px 20px rgba(0, 0, 0, .05),
25px 35px 20px rgba(0, 0, 0, .05),
25px 30px 30px rgba(0, 0, 0, .05),
inset -20px -20px 25px hsla(0, 0%, 100%, .9);
position: relative;
}
.water::before {
content: "";
position: absolute;
left: 24%;
top: 25%;
width: 16px;
height: 16px;
background: #fff;
border-radius: 50%;
}
效果:
圆形水滴做好了,那我们是不是可以改变其现状呢,只要改变border-radius就可以了
.water {
width: 120px;
height: 120px;
/*改变形状,使其弯曲*/
border-radius: 30% 70% 70% 30% / 30% 35% 65% 70%;
box-shadow: inset 20px 20px 20px rgba(0, 0, 0, .05),
25px 35px 20px rgba(0, 0, 0, .05),
25px 30px 30px rgba(0, 0, 0, .05),
inset -20px -20px 25px hsla(0, 0%, 100%, .9);
position: relative;
}
效果:
形状改变了,我们就让其动起来,动起来就算加上关键帧改变border-radius
.water {
width: 120px;
height: 120px;
/*改变形状,使其弯曲*/
border-radius: 30% 70% 70% 30% / 30% 35% 65% 70%;
box-shadow: inset 20px 20px 20px rgba(0, 0, 0, .05),
25px 35px 20px rgba(0, 0, 0, .05),
25px 30px 30px rgba(0, 0, 0, .05),
inset -20px -20px 25px hsla(0, 0%, 100%, .9);
position: relative;
/*添加动画关键帧*/
animation: waterMove 4s linear infinite;
}
.water::before {
content: "";
position: absolute;
left: 24%;
top: 25%;
width: 16px;
height: 16px;
background: #fff;
border-radius: 30% 70% 70% 30% / 30% 35% 65% 70%;
animation: waterMove 4s linear infinite;
}
/* 关键帧 */
@keyframes waterMove {
20% {
border-radius: 30% 70% 53% 47% / 28% 44% 56% 72%;
}
40% {
border-radius: 30% 70% 39% 61% / 34% 39% 61% 66%;
}
60% {
border-radius: 25% 75% 45% 55% / 40% 55% 45% 60%;
}
80% {
border-radius: 28% 72% 31% 69% / 32% 39% 61% 68%;
}
}
效果:
完成后我们就可以在这个水滴里面添加东西了,比如设计登录页面
<div class="login-container">
<div class="login-content">
<div class="login-box">
<form action="" class="login-form">
<h2>LOGIN</h2>
<div class="input-box">
<input type="text" placeholder="用户名"/>
</div>
<div class="input-box">
<input type="password" placeholder="密码"/>
</div>
<div class="input-box">
<input type="submit" value="登录"/>
</div>
</form>
</div>
<div class="login-btn forget-pwd">
<span>忘记</span>
<span>密码</span>
</div>
<div class="login-btn register"><span>注册</span></div>
</div>
</div>
