问题是当我将鼠标悬停在fb图标上时，它的背景颜色很少。边界是双倍我用1px边框..请帮帮我...抱歉我的英文不好。

Answer 1

我认为你需要做类似的事情：

.social-icon li a .ff:hover
{
    display: block; 
    width: 37px; 
    height: 32px;
}

.social-icon li a i
{
    left: 0;
    top: 0;
    color: #d2d2db;
    position: absolute
}

Answer 2

这是什么意思？将您的CSS更改为以下内容......

.social-icon {
  text-align: center;
  text-decoration: none;
}
.social-icon li {
  list-style: none;
  display: inline-block;
  float: left;
  position: relative;
}
.social-icon li a {
  display: inline-block;
  font-size: 18px;
  line-height: 28px;
  width: 35px;
  text-decoration: none;
  outline: none;
  height: 36px;
  border: 1px solid #000;
  border-top: 1px solid #000;
  border-bottom: 1px solid #000;
}

.social-icon li :hover{
  background-color: #345599;
  -webkit-transition-delay: 0.2s;
  -moz-transition-delay: 0.2s;
  -o-transition-delay: 0.2s;
  -ms-transition-delay: 0.2s;
  transition-delay: 0.2s;
  -webkit-transition: all 0.3s ease-in-out 0.2s;
  -moz-transition: all 0.3s ease-in-out 0.2s;
  -o-transition: all 0.3s ease-in-out 0.2s;
  -ms-transition: all 0.3s ease-in-out 0.2s;
  transition: all 0.3s ease-in-out 0.2s;
}

.social-icon li a:first-child {
  border-left: 1px solid #000;
}
.social-icon li a .ff {
  opacity: 0;
  background-color: rgba(255, 255, 255, 0.0);
  -webkit-transform: scale(5);
  -moz-transform: scale(5);
  -o-transform: scale(5);
  -ms-transform: scale(5);
  transform: scale(5);
  -webkit-transition: all 0.3s ease-in-out 0.2s;
  -moz-transition: all 0.3s ease-in-out 0.2s;
  -o-transition: all 0.3s ease-in-out 0.2s;
  -ms-transition: all 0.3s ease-in-out 0.2s;
  transition: all 0.3s ease-in-out 0.2s;
}
.social-icon li a .ff:hover {
  opacity: 1;
  background-color: rgba(255, 255, 255, 0.0);
  -webkit-transform: scale(1);
  -moz-transform: scale(1);
  -o-transform: scale(1);
  -ms-transform: scale(1);
  transform: scale(1);
  -webkit-transition-delay: 0.2s;
  -moz-transition-delay: 0.2s;
  -o-transition-delay: 0.2s;
  -ms-transition-delay: 0.2s;
  transition-delay: 0.2s;
}
.social-icon li a i {
  color: #d2d2db;
  position: absolute;
  top: 10px;
  left: 10px;
}

我添加了课程 .social-icon li：hover

我还将属性 background-color：rgba（255,255,255,0.0）; 添加到班级 .social-icon li a .ff：hover

我认为这更接近你想要的东西：

.social-icon {
  text-align: center;
  text-decoration: none;
}
.social-icon li {
  list-style: none;
  float: left;
  position: relative;
  height: 38px;
}
.social-icon li a{
  display: inline-block;
  font-size: 18px;
  line-height: 28px;
  width: 35px;
  text-decoration: none;
  outline: none;
  height: 36px;
  border-right: 1px solid #000;
  border-top: 1px solid #000;
  border-bottom: 1px solid #000;
}
.social-icon li:first-child {
  border-left: 1px solid #000;
}
.social-icon li .ff {
  opacity: 0;
  -webkit-transform: scale(5);
  -moz-transform: scale(5);
  -o-transform: scale(5);
  -ms-transform: scale(5);
  transform: scale(5);
  -webkit-transition: all 0.3s ease-in-out 0.2s;
  -moz-transition: all 0.3s ease-in-out 0.2s;
  -o-transition: all 0.3s ease-in-out 0.2s;
  -ms-transition: all 0.3s ease-in-out 0.2s;
  transition: all 0.3s ease-in-out 0.2s;
}
.social-icon li .ff:hover {
  opacity: 1;
  background-color: #345599;
  -webkit-transform: scale(1);
  -moz-transform: scale(1);
  -o-transform: scale(1);
  -ms-transform: scale(1);
  transform: scale(1);
  -webkit-transition-delay: 0.2s;
  -moz-transition-delay: 0.2s;
  -o-transition-delay: 0.2s;
  -ms-transition-delay: 0.2s;
  transition-delay: 0.2s;
}

.social-icon li a i {
  color: #d2d2db;
  position: absolute;
  padding: 10px;
  top: 0px;
  left: 0px;
}

.social-icon .fa-facebook {
    padding-right: 15px;
}

编辑：我更新了代码。仍然存在.ff对象比<li>容器大得多的问题。因此，您将在框外的空格中激活过渡。

Answer 4

您的第一胎选择器不正确。它选择列表的每个元素。这就是你有双边界的原因。

您的背景悬停仅选择<i>而不是整个<a>。因此，它似乎很小。
