SVG 简单动画

Question

我正在尝试学习如何使用 SVG 元素，因此我在 Illustrator 中制作了简单的图标/徽标。然后我在示例中使用了这个 SVG 图标：

@import url(http://fonts.googleapis.com/css?family=Lato);
 body {
  background-color: #2F2724;
  font-family: lato, sans-serif;
}
.main {
  text-align: center;
}
.letterS {
  fill: #fff;
  font-size: 180px;
  text-shadow: 0px 2px 2px #000;
}
#svgHex {
  display: block;
  margin: 40px auto;
  width: 350px;
}
.slogan {
  color: #D0E799;
  font-size: 60px;
  margin-top: 40px;
  margin-bottom: 0px;
  text-shadow: 0px 2px 2px #000;
}
.pSlogan {
  margin-top: 0px;
  font-size: 36px;
  color: #fff;
  text-shadow: 0px 2px 2px #000;
}

<div class="main">

里面几乎所有的代码都是由 Illustrator 生成的。我已将 id="svgHex" 添加到 SVG 并将 class="letterS" 添加到六边形内的“S”字母。

现在我想为六边形之外的那些白色元素设置动画，但我不知道如何在 CSS 中访问它们。我试图向单个多边形添加一个类并使用显示，但到目前为止没有任何效果。我真的不关心任何特定的动画，只是想学习如何使用它们。

我不确定我做的都是好还是坏的方法，有更好的方法来制作这种图标动画。

任何建议将不胜感激。我是初学者，请不要讨厌:)

除了@web-tiki 的回答，您还可以通过应用 ID 和类将 :hover 和关键帧动画应用于 SVG 的选定“组件/元素”。

例如，将鼠标悬停在“S”上。

svg text {
  transition: fill 0.5s ease;

svg text:hover {

@keyframes blinky {

我应该提到，如果您在 Illustrator 中使用多个命名图层，我相信这些图层名称会作为 ID 直接导出到 SVG 代码中。
