javascript - 悬停时的过渡图标

Question

我有这个代码

.pictos {
  display: block;
  height: 70px;
  margin: 160px 0 30px;
  padding: 0 17%;
  width: 100%;
}
.pictos > div {
  background: none repeat scroll 0 0 rgba(0, 0, 0, 0.2);
  border: 1px solid #fff;
  border-radius: 50%;
  display: table-row;
  float: left;
  height: 70px;
  width: 70px;
  margin: 0 0 0 50px;
}
.pictos a.standard:hover,
.pictos a.standard:focus {
  background: url("http://s11.postimg.org/91k4hiqe7/standard.png") no-repeat scroll 50% -39px rgba(120, 182, 55, 1);
}
.pictos > div a {
  border-radius: 50%;
  display: inline-block;
  height: 45px;
  margin: 12px;
  text-decoration: none;
  text-indent: -9999px;
  transition: all 500ms cubic-bezier(0.645, 0.045, 0.355, 1) 0s;
  width: 45px;
}
/* Hide this */

.pictos > div .standard-hover {
  border-radius: 50%;
  display: inline-block;
  height: 45px;
  margin: 12px;
  text-decoration: none;
  text-indent: -9999px;
  transition: all 500ms cubic-bezier(0.645, 0.045, 0.355, 1) 0s;
  width: 45px;
}
.pictos > div:first-child {} .pictos a.standard {
  background: url("http://s11.postimg.org/91k4hiqe7/standard.png") no-repeat scroll 50% 50% rgba(255, 255, 255, 1);
}
.pictos a.standard:hover span,
.pictos a.standard span:hover,
.pictos a.standard span:focus,
.pictos a.standard:focus span {
  display: block;
  opacity: 1;
}
.pictos a span::after {
  -moz-border-bottom-colors: none;
  -moz-border-left-colors: none;
  -moz-border-right-colors: none;
  -moz-border-top-colors: none;
  border-color: #78b637 rgba(120, 182, 55, 0) rgba(120, 182, 55, 0);
  border-image: none;
  border-style: solid;
  border-width: 6px;
  content: " ";
  height: 0;
  left: 50%;
  margin-left: -6px;
  pointer-events: none;
  position: absolute;
  top: 100%;
  width: 0;
}
.pictos a span {
  background: none repeat scroll 0 0 #78b637;
  border: medium none;
  border-radius: 9px;
  bottom: 50px;
  color: #efefef;
  font-family: "Montserrat-Regular", sans-serif;
  font-size: 13px;
  padding: 5px 0;
  position: relative;
  right: 77px;
  text-align: center;
  text-decoration: none;
  text-indent: 0;
  text-transform: uppercase;
  width: 200px;
}

<div class="pictos">
  <div>
    <a href="#" class="standard">
      <span>standard</span>
    </a>
    <a href="#" class="standard-hover">
      <span>standard</span>
    </a>
  </div>
</div>

我想要的是当您将鼠标悬停在链接上时，一个白色图标电话(如 http://s30.postimg.org/3l9qho5h9/standard_hover.png )从底部出现到绿色圆圈。当第一个图标移动到顶部时会发生这种情况。

感谢您的帮助。

                    url(http://s30.postimg.org/3l9qho5h9/standard_hover.png);
