如何使css平滑过渡

Question

我如何才能获得像这里这样的css过渡示例（下拉示例），到目前为止，我只更改了文本和背景颜色，但没有更改整个过渡效果（矩形在悬停时滚动，在取消悬停时平稳地向后滚动），知道我该如何实现吗？这是我的代码：

a.menulink
{
text-decoration: none;
color: #000000;
background-color: rgb(235,235,185);
-webkit-transition: color .25s linear;
transition: color .25s linear;
transition: background-color .15s linear .1;
}
a.menulink:hover
{
text-decoration: none;
color: #FFFFFF;
background-color: rgb(255,24,24);
-webkit-transition: color .25s linear, background-color .15s linear .1s;
transition: color .25s linear, background-color .15s linear .1s;
}

在之前感谢您

请参阅此演示

<a href="#" class="linkhover">
    <span hover-title="LINK HOVER">LINK HOVER</span>
</a>
.linkhover {
    display: inline-block;
    overflow: hidden;
    perspective: 400px;
    -webkit-perspective: 400px;
    perspective-origin: 50% 50%;
    -webkit-perspective-origin: 50% 50%;
}
.linkhover span {
    display: block;
    position: relative;
    transition: all 500ms ease;
    -webkit-transition: all 500ms ease;
    transform-origin: 50% 0%;
    -webkit-transform-origin: 50% 0%;
    transform-style: preserve-3d;
    -webkit-transform-style: preserve-3d;
}
.linkhover:hover span {
    transform: translate3d( 0px, 0px, -35px ) rotateX( 90deg );
    -webkit-transform: translate3d( 0px, 0px, -35px ) rotateX( 90deg );
}
.linkhover span:after {
    content: attr(hover-title);
    display: block;
    position: absolute;
    left: 0;
    top: 0;
    white-space: nowrap;
    color: white;
    background: red;
    transform-origin: 50% 0%;
    -webkit-transform-origin: 50% 0%;
    transform: translate3d( 0px, 100%, 0px ) rotateX( -90deg );
    -webkit-transform: translate3d( 0px, 100%, 0px ) rotateX( -90deg );
}

只需使用此即可。无需在"：hover"选择器中使用转换。

a.menulink{
text-decoration: none;
color: #000000;
background-color: rgb(235,235,185);
-webkit-transition: color .25s linear;
transition: color .25s linear;
transition: background-color .15s linear .1s;
}
a.menulink:hover
{
text-decoration: none;
color: #FFFFFF;
background-color: rgb(255,24,24);}
