CSS过渡如何使mouseout效果

我正在尝试找到一种方法，当您将光标从其移开时，黑色斑点会平滑地返回。更好的是，我想知道是否有可能使用CSS使Blob从左到右消失。另外，您对如何使Blob越过文本时文本变成白色有一个想法吗？非常感谢您的帮助！

* {
  margin: 0;
  padding: 0;
}

ul {
  display: flex;
  justify-content: flex-end;
  letter-spacing: 1px;
  align-items: center;
  padding: 30px 0;
  /*background-color: red;*/
}

li {
  text-align: center;
  font-family: "Trebuchet MS", Helvetica, sans-serif;
  list-style: none;
  padding: 0 30px;
  text-transform: uppercase;
  font-size: .71em;
}

ul li i {
  margin-left: 7px;
}

li a {
  position: relative;
  text-decoration: none;
  color: inherit;
}

li a::before {
  content: "";
  position: absolute;
  width: 0%;
  height: 1.3em;
  background-color: black;
  visibility: hidden;
  transition: width .2s;
}

li a:hover::before {
  width: 100%;
  visibility: visible;
}

由于已经将宽度设置为0％，因此无需使用可见性。您还可以调整位置以实现从左到右的转换。对于颜色，只需在a上添加另一个悬停声明：

ul {
  display: flex;
  justify-content: flex-end;
  letter-spacing: 1px;
  align-items: center;
  padding: 30px 0;
  /*background-color: red;*/
}

li {
  text-align: center;
  font-family: "Trebuchet MS", Helvetica, sans-serif;
  list-style: none;
  padding: 0 30px;
  text-transform: uppercase;
  font-size: .71em;
}

ul li i {
  margin-left: 7px;
}

li a {
  position: relative;
  text-decoration: none;
  color: inherit;
}

li a::before {
  content: "";
  position: absolute;
  z-index: -1;
  width: 0%;
  left: auto;
  right: 0;
  height: 1.3em;
  background-color: black;
  transition: width .2s, left .2s .2s, right .2s .2s;
}

li a:hover::before {
  width: 100%;
  left: 0;
  right: auto;
}

li a:hover {
  color: #fff;
}
<ul>
  <li><a href="#" title="home">home</a></li>
  <li><a href="#" title="text">text</a></li>
  <li><a href="#" title="image">image</a></li>
  <li><a href="#" title="slider">slider<i class="fa fa-angle-down" title="slider"></i></a></li>
  <li><a href="#" title="html">html<i class="fa fa-angle-down"></i></a></li>
  <li><a href="#" title="css">css</a></li>
</ul>

您还可以使用渐变来简化代码：

ul {
  display: flex;
  justify-content: flex-end;
  letter-spacing: 1px;
  align-items: center;
  padding: 30px 0;
  /*background-color: red;*/
}

li {
  text-align: center;
  font-family: "Trebuchet MS", Helvetica, sans-serif;
  list-style: none;
  padding: 0 30px;
  text-transform: uppercase;
  font-size: .71em;
}

ul li i {
  margin-left: 7px;
}

li a {
  position: relative;
  text-decoration: none;
  color: inherit;
  background: linear-gradient(#000, #000) left/0% 100% no-repeat;
  transition: 
    color 0.2s,
    background-size 0.2s, 
    background-position 0.2s 0.2s;
}

li a:hover {
  color: #fff;
  background-size: 100% 100%;
  background-position: right;
}
<ul>
  <li><a href="#" title="home">home</a></li>
  <li><a href="#" title="text">text</a></li>
  <li><a href="#" title="image">image</a></li>
  <li><a href="#" title="slider">slider<i class="fa fa-angle-down" title="slider"></i></a></li>
  <li><a href="#" title="html">html<i class="fa fa-angle-down"></i></a></li>
  <li><a href="#" title="css">css</a></li>
</ul>
