灌水动画

  • 772

我正在尝试制作动画以使圆圈看起来像是装满了水。

我遇到了两个错误，甚至无法通过第三个：

  1. 使用填充是错误的解决方案。
  2. 圆圈在填充后恢复为空（黑色）颜色
  3. 目前我正在使用 tags <img>，但我想将此效果移动到身体{background-image:}上，并且需要一些关于如何做到这一点的指导。

到目前为止我所尝试的：http: //jsfiddle.net/um0rnL56/1/ 

#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;
  }
}
<div id="banner">

css

1 个回答

  1. Best Answer

    这里有四种不同的选择：

    1. 使用缓动

    如果你在一个圆碗里装满液体，它的底部和顶部会比中间填充得更快（因为更宽的中间部分有更多的空间可以覆盖）所以，记住这个粗略的解释，动画应该：快速开始，在中间放慢速度，然后随着碗在顶部再次变窄而迅速结束。

    为此，我们可以使用 CSS3 的缓动特性：cub-bezier (.2, .6, .8, .4).

    请参阅下面的示例。

    （如果你想在easing这里定制，那么这里有一个很好的资源：http ://cubic-bezier.com/#.2,.6,.8,.4 ） 

    #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%;
  }
    <div id="banner">

</div>

    2. SVG 美味

    让我们更进一步。假设我们想用 为“水”添加一个波浪表面CSS。我们可以使用 SVG.
    我在 中创建了一个波浪形 SVG 图像Adobe Illustrator，然后使用单独的 CSS 动画对图像进行动画处理，使其在循环中从左向右移动：

    例子 

    #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);
    }
}
    <div id="banner">
<div class="fill">
    <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="300px" height="300px" viewBox="0 0 300 300" enable-background="new 0 0 300 300" xml:space="preserve">
      <path fill="#04ACFF" id="waveShape" d="M300,300V2.5c0,0-0.6-0.1-1.1-0.1c0,0-25.5-2.3-40.5-2.4c-15,0-40.6,2.4-40.6,2.4
	c-12.3,1.1-30.3,1.8-31.9,1.9c-2-0.1-19.7-0.8-32-1.9c0,0-25.8-2.3-40.8-2.4c-15,0-40.8,2.4-40.8,2.4c-12.3,1.1-30.4,1.8-32,1.9
	c-2-0.1-20-0.8-32.2-1.9c0,0-3.1-0.3-8.1-0.7V300H300z"/>
    </svg>
</div>
</div>

    3.带灌装线

    此示例包括一条填充线（大多数碗从顶部填充，而不是底部填充）。填充线首先从上到下进行动画处理，而该属性会animation-delay阻止填充进行动画处理，直到填充完成。 

    #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 {
  0% {
    transform: translate(-150px, 0);
  }
  100% {
    transform: translate(0, 0);
  }
}
    <div id="banner">
  <div class="pour"></div>
  <div class="fill">
    <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="300px" height="300px" viewBox="0 0 300 300" enable-background="new 0 0 300 300" xml:space="preserve">

    4. 有严重的金光闪闪（具有美丽的美学）

    此示例添加了更多属性CSS以使其更逼真。
