CSS 加水动画

Question

提问by Arian Faurtosh

I am trying to get a wipe up animation to make a circle look like it's filling with water. I've run into two errors, and haven't been able to even tackle the 3rd one:

我正在尝试制作一个擦拭动画，使一个圆圈看起来像是装满了水。我遇到了两个错误，甚至无法解决第三个错误：

It fills up the wrong way
~~It resets to empty (black) after it has filled~~*
For now, I am using the <img>tags, but I would like to move this effect to body { background-image: }and need some direction on how to do this.

它以错误的方式填充
~~它在填充后重置为空（黑色）~~*
现在，我正在使用<img>标签，但我想将此效果移动到body { background-image: }并且需要一些关于如何执行此操作的指导。

What I have tried so far:

到目前为止我尝试过的：

#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">
  <div>
    <img src="http://i.imgur.com/vklf6kK.png" />
  </div>
  <div>
    <img src="http://i.imgur.com/uszeRpk.png" />
  </div>
</div>

Giving it a default mask position as @anpsmnsuggested, doesn't reset it to black anymore.

按照@anpsmn 的建议为其提供默认蒙版位置，不再将其重置为黑色。

This can be achieved with a single div and a ::beforepseudo element:

这可以通过一个 div 和一个伪元素来实现::before：

The #banneris given border-radius: 50%to create a circle and overflow: hiddento clip its children inside it
The ::beforepseudo element is animated to 100% height and the animation is paused at 100% using the forwardsvalue. It begins at the bottom with the use of bottom: 0
The background images would be applied in place of the black and blue backgrounds on #bannerand #banner::before

在#banner被赋予border-radius: 50%创建一个圆圈，并overflow: hidden夹及其子里面
所述::before伪元件被动画化以100％的高度，并且动画效果使用在100％暂停的forwards值。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和#banner::before

Compatibility:IE10+ and all modern browsers. The -webkit-prefixed property is most likely no longer necessary for your keyframe animations. Check the browser compatibility chart over here on caniuse.com

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

Working Example

工作示例

I have added the cubic-bezier(.2,.6,.8,.4)which is explained in @ChrisSpittles answer. It provides a neat effect!

我已经添加了cubic-bezier(.2,.6,.8,.4)在@ChrisSpittles answer 中解释的内容。它提供了一个整洁的效果！

#banner {
  width: 300px;
  height: 300px;
  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%;
  }
}

回答by Chris Spittles

Here are four different versions to supplement @misterManSam's brilliant answer.

这里有四个不同的版本来补充@misterManSam 的精彩回答。

1. With Easing

1. 宽松

Explanation

解释

If you filled up a circular bowl full of liquid, it would fill faster at the bottom and top than it would in the middle (because there is more area to cover in the wider middle section). So, with that crude explanation in mind, the animation needs to: start fast, slow in the middle, and then finish fast when the bowl narrows again at the top.

如果你在一个圆形碗里装满液体，它在底部和顶部的填充速度会比在中间更快（因为在更宽的中间部分有更多的区域可以覆盖）。因此，考虑到这个粗略的解释，动画需要：快速开始，中间缓慢，然后当碗在顶部再次变窄时快速结束。

To do this we can use a CSS3 easing function: cubic-bezier(.2,.6,.8,.4).

要做到这一点，我们可以使用CSS3缓解功能：cubic-bezier(.2,.6,.8,.4)。

Have a look at the example below.

看看下面的例子。

(If you want to tweak the easing here is a great resource: http://cubic-bezier.com/#.2,.6,.8,.4)

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

Example:

例子：

#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 Deliciousness

2. SVG 美味

Let's take this one step further? What if we wanted to add a wavy surface on the "water" using CSS? We can do this using the amazing SVG. I created a wavy SVG image in Adobe Illustrator and then animated that to travel from left to right on a loop with a separate CSS animation and voila:

让我们更进一步？如果我们想使用 CSS 在“水”上添加波浪表面怎么办？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 SVG 图像，然后使用单独的 CSS 动画将其动画化为从左到右循环移动，瞧：

Example

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">

    </svg>

</div>

3. With pour line

3.带浇注线

This example includes a pour line (most bowls fill from the top, not the bottom). The pour line first animates from top to bottom while an animation-delayproperty prevents the fill animation from happening until the pour has finished.

此示例包括一条倾倒线（大多数碗从顶部填充，而不是底部）。浇筑线首先从上到下动画，而animation-delay属性阻止填充动画发生，直到浇筑完成。

#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);
  }
}
