填充水动画

Ari*_*osh 59 css svg css3 css-animations css-shapes

我试图通过一个擦拭动画来制作一个看起来像是充满水的圆圈.我遇到了两个错误,甚至无法解决第三个错误:

  1. 它填补了错误的方式
  2. 它填满后重置为空(黑色)*
  3. 目前,我正在使用这些<img>标签,但我想将此效果移至body { background-image: }需要指导如何执行此操作.

到目前为止我尝试了什么:

#banner {
  width: 300px;
  height: 300px;
  position: relative;
}
#banner div {
  position: absolute;
}
#banner div:nth-child(2) {
  -webkit-animation: wipe 6s;
  -webkit-animation-delay: 0s;
  -webkit-animation-direction: up;
  -webkit-mask-size: 300px 3000px;
  -webkit-mask-position: 300px 300px;
  -webkit-mask-image: -webkit-gradient(linear, left bottom, left top, color-stop(0.00, rgba(0, 0, 0, 1)), color-stop(0.25, rgba(0, 0, 0, 1)), color-stop(0.27, rgba(0, 0, 0, 0)), color-stop(0.80, rgba(0, 0, 0, 0)), color-stop(1.00, rgba(0, 0, 0, 0)));
}
@-webkit-keyframes wipe {
  0% {
    -webkit-mask-position: 0 0;
  }
  100% {
    -webkit-mask-position: 300px 300px;

给它一个默认的掩码位置@anpsmn建议,不再将它重置为黑色.

这里有四个不同的版本来补充@ misterManSam的精彩答案.

1.随着轻松


说明

如果你装满了一个装满液体的圆形碗,它会在底部和顶部填充比在中间填充的更快(因为在更宽的中间部分有更多的区域可以覆盖).因此,考虑到粗略的解释,动画需要:快速开始,中间慢,然后当碗在顶部再次变窄时快速完成.

为此,我们可以使用CSS3缓动函数:cubic-bezier(.2,.6,.8,.4).

看看下面的例子.

(如果你想在这里调整缓动是一个很好的资源:http://cubic-bezier.com/#.2,.6,.8,.4)

例:

#banner {
  width: 150px;
  height: 150px;
  position: relative;
  background: #000;
  border-radius: 50%;
  overflow: hidden;
}
#banner::before {
  content: '';
  position: absolute;
  background: #04ACFF;
  width: 100%;
  bottom: 0;
  animation: wipe 5s cubic-bezier(.2,.6,.8,.4) forwards;
}
@keyframes wipe {
  0% {
    height: 0;
  }
  100% {
    height: 100%;
  }
}

2. SVG美味

让我们更进一步吧?如果我们想用CSS在"水"上添加波浪状表面怎么办?我们可以使用惊人的SVG来做到这一点.我在Adobe Illustrator中创建了一个波浪形的SVG图像,然后将其设置为动画,以便在一个循环中从左到右行进,并带有单独的CSS动画,并且瞧瞧:

#banner {
    border-radius: 50%;
    width: 150px;
    height: 150px;
    background: #000;
    overflow: hidden;
    backface-visibility: hidden;
    transform: translate3d(0, 0, 0);
}
#banner .fill {
    animation-name: fillAction;
    animation-iteration-count: 1;
    animation-timing-function: cubic-bezier(.2, .6, .8, .4);
    animation-duration: 4s;
    animation-fill-mode: forwards;
}
#banner #waveShape {
    animation-name: waveAction;
    animation-iteration-count: infinite;
    animation-timing-function: linear;
    animation-duration: 0.5s;
    width:300px;
    height: 150px;
    fill: #04ACFF;
}
@keyframes fillAction {
    0% {
        transform: translate(0, 150px);
    }
    100% {
        transform: translate(0, -5px);
    }
}
@keyframes waveAction {
    0% {
        transform: translate(-150px, 0);
    }
    100% {
        transform: translate(0, 0);
    }

3.用浇注线


此示例包括浇注线(大多数碗从顶部填充,而不是从底部填充).浇筑线首先从上到下进行动画处理,而animation-delay属性可防止填充动画发生,直到浇筑完成为止.

#banner {
  border-radius: 50%;
  width: 150px;
  height: 150px;
  background: #000;
  overflow: hidden;
  backface-visibility: hidden;
  transform: translate3d(0, 0, 0);
  position: relative;
}

#banner .fill {
  transform: translateY(150px);
  animation-name: fillAction;
  animation-iteration-count: 1;
  animation-timing-function: cubic-bezier(.2, .6, .8, .4);
  animation-duration: 4s;
  animation-fill-mode: forwards;
  animation-delay: 0.25s;
}

#banner .pour {
  width: 6px;
  position: absolute;
  left: 50%;
  margin-left: -3px;
  bottom: 0;
  top: 0;
  background: #009ae6;
  animation-name: pourAction;
  animation-timing-function: linear;
  animation-duration: 0.25s;
}

#banner #waveShape {
  animation-name: waveAction;
  animation-iteration-count: infinite;
  animation-timing-function: linear;
  animation-duration: 0.5s;
  width: 300px;
  height: 150px;
  fill: #04ACFF;
}

@keyframes pourAction {
  0% {
    transform: translateY(-100%);
  }
  100% {
    transform: translateY(0);
  }
}

@keyframes fillAction {
  0% {
    transform: translateY(150px);
  }
  100% {
    transform: translateY(-5px);
  }
}

@keyframes waveAction {

    transform: translate(-150px, 0);
  }
  100% {

  • Svg one非常好!+1 (8认同)
  • @JamesBarracca这使用SASS来设置大小:http://codepen.io/chrissp26/pen/KWvPjG?edit = 0100更改`$ width`变量以满足您的需要. (2认同)

这可以通过一个div和一个伪元素来实现::before:

  • #banner被赋予border-radius: 50%创建一个圆圈,并overflow: hidden夹及其子里面

  • ::before伪元素设置为100%高度,并使用forwards暂停动画100%.它从底部开始使用bottom: 0

  • 背景图像将在地方上的黑色和蓝色背景的应用#banner#banner::before

兼容性: IE10 +和所有现代浏览器.该-webkit-前缀属性是最有可能不再需要你的关键帧动画.在caniuse.com上查看浏览器兼容性图表

我添加了cubic-bezier(.2,.6,.8,.4) @ChrisSpittles答案中解释的内容.它提供了一个整洁的效果!

纯 CSS,没有 JavaScript,没有 SVG。开关overflow: hidden关断.shape 来看看它是如何工作的简单。

使用CSS 动画制作。你可以罚款填充动画 @keyframes

如果您希望使用 JavaScript 加载填充 - 您可以访问.waveelement.js。的top: 50%;是0%,并且top: -75%是负载的100%。您可以根据需要使用这些数字。

.shape {
  width: 180px;
  height: 180px;
  border-radius: 50%;
  overflow: hidden;
  position: relative;
}

.shape:after {
