SVG 图标鼠标悬停动画

Question

我正在使用下面的 SVG 创建一个网页，它是两个不同 SVG 图标代码的组合。

我想在 mouseover 后将图标的可见性从可见更改为隐藏，反之亦然。

下面CSS我写了同样的东西，但它不起作用。

#icon1:hover {
  visibility: hidden;
}

#icon2:hover {
  visibility: visible;
}

<svg xmlns="http://www.w3.org/2000/svg" width="30" height="30" fill="#E0EADF" class="bi bi-emoji-smile mr-2" viewBox="0 0 17 17" style="position: relative;top: 0px;left: 0px;">
  <path visibility="visible" d="M8 15A7 7 0 1 1 8 1a7 7 0 0 1 0 14zm0 1A8 8 0 1 0 8 0a8 8 0 0 0 0 16z"/>
  <path visibility="visible" id="icon1" d="M4.285 9.567a.5.5 0 0 1 .683.183A3.498 3.498 0 0 0 8 11.5a3.498 3.498 0 0 0 3.032-1.75.5.5 0 1 1 .866.5A4.498 4.498 0 0 1 8 12.5a4.498 4.498 0 0 1-3.898-2.25.5.5 0 0 1 .183-.683zM7 6.5C7 7.328 6.552 8 6 8s-1-.672-1-1.5S5.448 5 6 5s1 .672 1 1.5zm4 0c0 .828-.448 1.5-1 1.5s-1-.672-1-1.5S9.448 5 10 5s1 .672 1 1.5z"/>

</svg>

你能指导我如何实现这一目标吗？是否可以创建一个 CSS 动画，以便以 5 秒的间隔无限改变可见性？

Answer 1

似乎工作正常，但一旦将 visibility 设置为隐藏，您就不再悬停了。也许改用描边颜色透明？

然后添加一个过渡。

svg {
  height: 90vh;
  display: block;
  margin: 2em auto;
}

svg path {
  stroke: red;
  fill: none;
  transition: stroke 1s ease;
}

#icon1:hover,
#icon2:hover {
  stroke: transparent;
}

Answer 2

尝试添加 svg infront :

svg:hover #icon1{
  visibility: hidden;
}
svg:hover #icon2{
  visibility: visible;
}

<svg xmlns="http://www.w3.org/2000/svg" width="30" height="30" fill="violet" class="bi bi-emoji-smile mr-2" viewBox="0 0 17 17" style="position: relative;top: 0px;left: 0px;">
          <path visibility="visible" d="M8 15A7 7 0 1 1 8 1a7 7 0 0 1 0 14zm0 1A8 8 0 1 0 8 0a8 8 0 0 0 0 16z"/>
          <path visibility="visible" id="icon1" d="M4.285 9.567a.5.5 0 0 1 .683.183A3.498 3.498 0 0 0 8 11.5a3.498 3.498 0 0 0 3.032-1.75.5.5 0 1 1 .866.5A4.498 4.498 0 0 1 8 12.5a4.498 4.498 0 0 1-3.898-2.25.5.5 0 0 1 .183-.683zM7 6.5C7 7.328 6.552 8 6 8s-1-.672-1-1.5S5.448 5 6 5s1 .672 1 1.5zm4 0c0 .828-.448 1.5-1 1.5s-1-.672-1-1.5S9.448 5 10 5s1 .672 1 1.5z"/>

Answer 3

对于 CSS 改变图标可见性的动画尝试下面

.icon_animate_1{
  animation: icon_frame1 3s step-end infinite;
}

@keyframes icon_frame1{
  0% {opacity: 1;}
  90% {opacity: 0;}
  100% {opacity: 1;}
}

.icon_animate_2{
  animation: icon_frame2 3s step-end infinite;
}

@keyframes icon_frame2{
  0% {opacity: 0;}
  90% {opacity: 1;}
  100% {opacity: 0;}
}
