html - 内联 CSS 图像过渡

Question

我想实现以下效果:在 CSS 下方，悬停时，做一个“老虎机效果”，在垂直旋转木马中滚动图标(请参阅下面的 css 了解详细信息)。 由于我为我的网站使用的托管限制，我不能使用任何外部图标库，所以我想达到同样的效果，将 css 粘贴到 header 中并将其与 img HTML 中的标记。

你能帮我修改这个 css 以便它真正适用于我的图像吗？

感谢大家的包容和帮助。

        -webkit-transform: translateY(0);
        transform: translateY(0)
    }
}

根据要求，还添加了 HTML 代码段，目前无法使用上述 css:

<div style="padding: 30px 0; padding-left: 0px; margin-left: 0px; margin-right: 0px; text-align: center">
            <div class="col-xs-12">
                                <ul class="social-media-share-buttons">
                    <li>
    <a target="_blank" href="https://www.facebook.com/sharer/sharer.php?u=https://www.mywebsite.com" class="btn btn-link social_share facebook" rel="nofollow" data-social_name="facebook" data-post_id="" data-social_type="share" data-location="inline">
        <img class="social-media-share-buttons-icon" src="facebook_icon.png">
        <div style="color: #fff; line-height: 2; font-weight: 700;">Facebook</div>
    </a>
</li>

你不需要动画。只需使用转换和转换就可以了:这里有一些例子:

ul {
  text-align: center;
  padding: 0;
}

li {
  list-style-type: none;
}

a {
  display: inline-block;
  position: relative;
  height: 40px;
  background: #4456aa;
  line-height: 40px;
  overflow: hidden;
  color: white;
  text-decoration: none;
  font-family: sans-serif;
  border: 1px solid transparent;
  transition: all 0.5s ease 0.5s;
}

a div {
  padding: 0 30px;
}

a img {
  transition: all ease 1s;
  position: absolute;
  top: 100%;
  left: 0;
  bottom: 0;
  width: 30px;
  margin: auto;
  opacity: 0;
}

a:hover {
  transition: all ease 0.5s;
}

a:hover {
  background: #ffffff;
  border: 1px solid #000000;
  color: #000000;
}

a:hover img {
  transition: all 0.5s ease 0.5s;
  opacity: 1;
  top: 0;
  bottom: 0;
}

<ul class="social-media-share-buttons">
  <li>
    <a target="_blank"
       href="https://www.facebook.com/sharer/sharer.php?u=https://www.mywebsite.com"
       class="btn btn-link social_share facebook"
       rel="nofollow"
       data-social_name="facebook"
       data-post_id=""
       data-social_type="share"
       data-location="inline">
        <img class="social-media-share-buttons-icon" 
             src="https://image.flaticon.com/icons/png/128/20/20837.png">
        <div>Facebook</div>
    </a>
  </li>
</ul>
