在横幅 css 动画上滑动文本

Question

我想在横幅上从左到右translateX 文字。我参考了这个网站上的动画https://pereiraodell.com/

他们使用 jQuery/javaScript 来制作动画。我想使用 CSS 获得相同的效果。

我正在尝试使用 CSS 复制相同的效果，但我的效果不如参考中给出的平滑。

在引用的站点中，文字动画速度逐渐变慢，不透明度设置完美。我无法在我的代码中产生相同的效果。也许我错过了关键帧中的一些断点。 fiddle

我想在悬停时显示这个动画，这样当用户悬停时，文本应该回到动画中的原始位置。

.banner{
  width:500px;
  height:300px;
  background-color:green;
  border-radius:4px;
  overflow:hidden;
  padding-left:20px
}

.content{
  width:200px
}

.title{
  transform:translateX(-1000px);
  font-size:20px;
  color:#fff;
  padding-top:10px
}
.description{
  transform:translateX(-1000px);
  font-size:20px;
  color:#fff;
  padding-top:10px
}

.banner:hover .title{
  animation: slideInRight 1s;
  animation-fill-mode:forwards
}

.banner:hover .description{
  animation: slideInRight 1s 80ms;
  animation-fill-mode:forwards
}

@keyframes slideInRight {
  0% {
    transform: translateX(-100px);
    opacity: 0;
  }
  50%{
    opacity: 0.2;
  }
  80%{
    opacity: 0.6;
  }
  100% {
    transform: translateX(0);
    opacity: 1
  }
}

编辑： 这是我一直在谈论的修复，我在路径.banner .content .title 和.banner .content .description 上应用了动画。我已经编辑了你的小提琴。我默认将.content 设为display:none。当mouseenter 事件被触发时，.content 更改为display:block，然后应用动画。我希望它有所帮助。我已经更新了小提琴的链接。

$(".banner").mouseenter(function(){
	$(".content").css("display","block");
});

.banner{
  width:500px;
  height:300px;
  background-color:green;
  border-radius:4px;
  overflow:hidden;
  padding-left:20px
}

.content{
  width:200px;
  display:none;
}

.title{
  transform:translateX(-1000px);
  font-size:20px;
  color:#fff;
  padding-top:10px
}
.description{
  transform:translateX(-1000px);
  font-size:20px;
  color:#fff;
  padding-top:10px
}

.banner .content .title{
  animation: slideInRight 1s;
  animation-fill-mode:forwards;
}
.banner .content .description{
  animation: slideInRight 1s;
  animation-fill-mode:forwards;
}

@keyframes slideInRight {
  0% {
    transform: translateX(-100px);
    opacity: 0;
  }
  50%{
    opacity: 0.2;
  }
  80%{
    opacity: 0.6;
  }
  100% {
    transform: translateX(0);
    opacity: 1
  }
}

直到在 css 脚本中我确实改变了 @keyframe slideInRight {} 的位置，它才起作用，我在调用它之前把它放在了它然后它对我有用。
