Question

我想在滑块上从上到下为文本设置动画。这是我用来动画的css：

HTML：

 <p class="rg5 slideInDown" id="text-animation">mobile</p>

的CSS：

.rg5 {
  font-family: roboto sans-serif;;
  font-size: 52px;
  color: #ffffff;
  margin-bottom: 10%;
  line-height: 1;
  text-transform: uppercase;
  transition: 1s ease-in-out;
  animation: slidein 5s infinite;
  -webkit-transition: 1s ease-in-out;
  -moz-transition: 1s ease-in-out;
  -o-transition: 1s ease-in-out;
  -webkit-animation: slidein 5s infinite;
  -moz-animation: slidein 5s infinite; 
  -o-animation: slidein 5s infinite;
  animation-fill-mode: forwards;
}
.slidein {
  -moz-animation-duration: 5s;
  -webkit-animation-duration: 5s;
  animation-duration: 5s;
  -moz-animation-name: slidein;
  -webkit-animation-name: slidein;
  animation-name: slidein;
  -moz-animation-iteration-count: 3;
  -webkit-animation-iteration-count: 3;
  animation-iteration-count: 3;
  -moz-animation-direction: alternate;
  -webkit-animation-direction: alternate;
  animation-direction: alternate;
}
@-moz-keyframes slidein {
  from { 
   -moz-transform: translate(1,-30em) scale(1.2);
}
  to { 
    -moz-transform: translate(1em,1) scale(1.2);
  }
}
@-webkit-keyframes slidein {
  from { -webkit-transform: translate(0s,-20em) scale(1.2);
  }
  to { -webkit-transform: translate(0em,0) scale(1.2);
  }  
}
@keyframes slidein {
  from { 
    transform: translate(0,-20em) scale(1.2);
  }
  to { 
    transform: translate(0em,0) scale(1.2);
  }
}

它在从上到下滑动时工作得很好，但动画之间应该有15秒的时间间隔。

Answer 1

这可以使用纯css来完成，不建议使用setInterval。

您可以使用animation-iteration-count: infinite;＆amp; animation-delay: 15s;了解后续动画之间的时间差距。

参考代码：

.rg5 {
  font-family: roboto sans-serif;
  font-size: 52px;
  color: black;
  margin-bottom: 10%;
  line-height: 1;
  text-transform: uppercase;
  transition: 1s ease-in-out;
  animation: slidein 5s infinite;
  -webkit-transition: 1s ease-in-out;
  -moz-transition: 1s ease-in-out;
  -o-transition: 1s ease-in-out;
  -webkit-animation: slidein 5s infinite;
  -moz-animation: slidein 5s infinite;
  -o-animation: slidein 5s infinite;
  animation-fill-mode: forwards;
}

.slidein {
  -webkit-animation-delay: 15s; /* Safari 4.0 - 8.0 */
  -moz-animation-delay: 15s;
  animation-delay: 15s;
}

@-moz-keyframes slidein {
  from {
    -moz-transform: translate(1, -30em) scale(1.2);
  }
  to {
    -moz-transform: translate(1em, 1) scale(1.2);
  }
}

@-webkit-keyframes slidein {
  from {
    -webkit-transform: translate(0s, -20em) scale(1.2);
  }
  to {
    -webkit-transform: translate(0em, 0) scale(1.2);
  }
}

@keyframes slidein {
  from {
    transform: translate(0, -20em) scale(1.2);
  }
  to {
    transform: translate(0em, 0) scale(1.2);
  }
}

<p class="rg5 slideInDown" id="text-animation">mobile</p>

Answer 2

您可以使用setInterval函数保持15秒的时间间隔。

setInterval(function()
{ 
     your_function(); 
}, 15000);

如何在固定的时间间隔后滑动文本
