我正在尝试制作省略号动画,并想知道是否可以使用 CSS 动画...

所以它可能就像

Loading...
Loading..
Loading.
Loading...
Loading..

基本上就这样继续下去。有任何想法吗?

@xec 答案的略微修改版本怎么样:http: //codepen.io/thetallweeks/pen/yybGra

HTML

添加到元素的单个类:

<div class="loading">Loading</div>

CSS

使用steps. 查看 MDN 文档

.loading:after {
  overflow: hidden;
  display: inline-block;
  vertical-align: bottom;
  -webkit-animation: ellipsis steps(4,end) 900ms infinite;      
  animation: ellipsis steps(4,end) 900ms infinite;
  content: "\2026"; /* ascii code for the ellipsis character */
  width: 0px;
}

@keyframes ellipsis {
  to {
    width: 20px;    
  }
}

@-webkit-keyframes ellipsis {
  to {
    width: 20px;    
  }
}

@xec 的答案对点有更多的滑入效果,而这允许点立即出现。

您可以尝试使用animation-delay property和时间每个省略号字符。在这种情况下,我将每个省略号字符放在 a 中<span class>,这样我就可以分别为它们设置动画。

我做了一个演示,它并不完美,但它至少说明了我的意思:)

我的示例中的代码:

HTML

Loading<span class="one">.</span><span class="two">.</span><span class="three">.</span>​

CSS

.one {
    opacity: 0;
    -webkit-animation: dot 1.3s infinite;
    -webkit-animation-delay: 0.0s;
    animation: dot 1.3s infinite;
    animation-delay: 0.0s;
}

.two {
    opacity: 0;
    -webkit-animation: dot 1.3s infinite;
    -webkit-animation-delay: 0.2s;
    animation: dot 1.3s infinite;
    animation-delay: 0.2s;
}

.three {
    opacity: 0;
    -webkit-animation: dot 1.3s infinite;
    -webkit-animation-delay: 0.3s;
    animation: dot 1.3s infinite;
    animation-delay: 0.3s;
}

@-webkit-keyframes dot {
    0% {
        opacity: 0;
    }
    50% {
        opacity: 0;
    }
    100% {
        opacity: 1;
    }
}

@keyframes dot {
    0% {
        opacity: 0;
    }
    50% {
        opacity: 0;
    }
    100% {
        opacity: 1;
    }
}

即使是更简单的解决方案,效果也很好!

<style>
    .loading::after {
      display: inline-block;
      animation: dotty steps(1,end) 1s infinite;
      content: '';
    }
    
    @keyframes dotty {
        0%   { content: ''; }
        25%  { content: '.'; }
        50%  { content: '..'; }
        75%  { content: '...'; }
        100% { content: ''; }
    }
</style>
<div class="loading">Loading</div>

只是用动画编辑了内容,而不是隐藏一些点......

在这里演示:https ://jsfiddle.net/f6vhway2/1/


编辑: 感谢@BradCollins指出这content不是动画属性

目前,(2021) 这适用于 Chrome/WebKit/Blink/Electron 和 Firefox 以及新版本的 Edge。

简短的回答是“不是真的”。但是,您可以使用动画宽度和隐藏溢出,并且可能会获得“足够接近”的效果。(以下代码仅适用于 firefox,根据需要添加供应商前缀)。

html

<div class="loading">Loading</div>

css

.loading:after {
    overflow: hidden;
    display: inline-block;
    vertical-align: bottom;
    -moz-animation: ellipsis 2s infinite;
    content: "\2026"; /* ascii code for the ellipsis character */
}
@-moz-keyframes ellipsis {
    from {
        width: 2px;
    }
    to {
        width: 15px;
    }
}

似乎 chrome 在为伪元素设置动画时存在问题。一个简单的解决方法是将省略号包装在它自己的元素中。查看http://jsfiddle.net/MDzsR/4/

后期添加,但我找到了一种支持居中文本的方法。

<element>:after {
    content: '\00a0\00a0\00a0';
    animation: progress-ellipsis 5s infinite;
}

@keyframes progress-ellipsis {
    0% {
        content: '\00a0\00a0\00a0';
    }
    30% {
        content: '.\00a0\00a0';
    }
    60% {
        content: '..\00a0';
    }
    90% {
        content: '...';
    }
}

您可以制作动画clipclip-path如果您不需要 IE 支持则更好)

div {
  position: relative;
  display: inline-block;
  font-size: 1.4rem;
}

div:after {
  position: absolute;
  margin-left: .1rem;
  content: ' ...';
  display: inline-block;
  animation: loading steps(4) 2s infinite;
  clip: rect(auto, 0px, auto, auto);
}

@keyframes loading {
  to {
    clip: rect(auto, 20px, auto, auto);
  }
}
<div>Loading</div>

好吧,实际上有一种纯粹的 CSS 方法可以做到这一点。

我从 CSS Tricks 中获得了示例,但它也在 Internet Explorer 中得到支持(我已经在 10+ 中对其进行了测试)。

查看演示:http: //jsfiddle.net/Roobyx/AT6v6/2/

HTML:

<h4 id="searching-ellipsis"> Searching
    <span>.</span>
    <span>.</span>
    <span>.</span>
</h4>

CSS:

@-webkit-keyframes opacity {
  0% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=100);
    opacity: 1;
  }
  100% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
    opacity: 0;
  }
}

@-moz-keyframes opacity {
  0% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=100);
    opacity: 1;
  }

  100% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
    opacity: 0;
  }
}

@-webkit-keyframes opacity {
  0% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=100);
    opacity: 1;
  }
  100% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
    opacity: 0;
  }
}

@-moz-keyframes opacity {
  0% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=100);
    opacity: 1;
  }
  100% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
    opacity: 0;
  }
}

@-o-keyframes opacity {
  0% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=100);
    opacity: 1;
  }
  100% {
    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
    opacity: 0;
  }
}

@keyframes opacity {
