页面的head部分设置好CSS样式，请注意一下:before、:after和:hover之类的CSS选择器，transform: translateY(-10px);这类的可以自行尝试调整效果的，完整CSS代码如下：

body {
  background: #2D2D34;
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
  font-family: 'Microsoft YaHei','Lantinghei SC','Open Sans',Arial,'Hiragino Sans GB','STHeiti','WenQuanYi Micro Hei','SimSun',sans-serif;
}

.box {
  position: relative;
  width: 120px;
  height: 50px;
  display: flex;
  justify-content: center;
  align-items: center;
  margin: 15px;
  color: #F27059;
}

.item {
  text-transform: uppercase;
  letter-spacing: 2px;
  font-size: 14px;
  z-index: 99;
  display: flex;
  justify-content: center;
  align-items: center;
  transition: 0.4s all ease;
}

.one:before, .one:after {
  position: absolute;
  content: '';
  width: 100%;
  height: 2px;
  background: #F27059;
  transition: 0.4s all ease;
}
.one:before {
  top: 0;
}
.one:after {
  bottom: 0;
}
.one .item:before, .one .item:after {
  position: absolute;
  top: 0;
  content: '';
  height: 100%;
  width: 2px;
  background: #F27059;
  transition: 0.4s all ease;
  z-index: -1;
}
.one .item:before {
  left: 0;
}
.one .item:after {
  right: 0;
}
.one:hover:before, .one:hover:after {
  transition: 0.4s all ease;
}
.one:hover:before {
  transform: translateY(-10px);
}
.one:hover:after {
  transform: translateY(10px);
}
.one:hover .item {
  color: white;
}
.one:hover .item:before, .one:hover .item:after {
  width: 100%;
  transition: 0.4s all ease;
}

.two {
  box-sizing: border-box;
  border: 2px solid #F27059;
  position: relative;
}
.two:before {
  position: absolute;
  content: '';
  width: 0;
  height: 50px;
  transition: 0.4s all ease;
  background: #F27059;
  left: 0;
  z-index: -1;
}
.two:hover {
  color: white;
}
.two:hover:before {
  width: 100%;
  transition: 0.4s all ease;
}

页面的body部分比较简单，两个div容器存放不同的按钮即可，代码如下：

<div class="box one">
  <div class="item">上下描边</div>
</div>

<div class="box two">
  <div class="item">左侧滑入</div>
</div>
