您可以使用伪元素来做到这一点。这是代码：

.btn-group .button {
  background-color: #fffff1;
  border: 0px solid black;
  border-radius: 8px;
 /* border-bottom: 1px solid black;*/
  color: #3c4043;
  padding: 15px 32px;
  text-align: center;
  text-decoration: none;
  font-size: 16px;
  cursor: pointer;
  width: 150px;
  display: block;
}

.button {
position: relative;
margin-bottom: 1rem;
box-sizing:border-box;
}

.button::after{
  content: '';
  position: absolute;
  bottom: 0;
  width: 100px;
  height: 1px;
  background: black;
  left: 50%;
  transform: translateX(-50%);
}

.button1 {
 /* border-bottom: 1px solid black;*/
}

.btn-group .button:not(:last-child) {
  
}

.btn-group .button:hover {
  background-color: #fffff1;
  box-shadow: 0 0px 4px 0 rgba(0,0,0,0.24), 0 0px 32px 0 rgba(0,0,0,0.19);
}

您可以使用伪元素 after 来完成这项工作。以下是我所做的您应该厌倦的更改：

.button {
  background-color: salmon /* so you can see the changes easier */
  position: relative /* this is so we can anchor the :after element */
}
.button:after {
  content: "";
  background: black;

  /* so we can adjust the position of the border bottom */
  position: absolute;

  /* bottom: 0 is to put it at the bottom*/
  bottom: 0;

  /* left: 5% is to center it */
  left: 5%;

  height: 1px;
  width: 90%;
}

.btn-group .button {
  /* background-color: #fffff1; */
  background-color: salmon;
  border: none;
  border-radius: 8px;
  color: #3c4043;
  padding: 15px 32px;
  text-align: center;
  text-decoration: none;
  font-size: 16px;
  cursor: pointer;
  width: 150px;
  display: block;
  position: relative;
}

.btn-group .button:after {
  content: "";
  background: black;
  position: absolute;
  bottom: 0;
  left: 5%;
  height: 1px;
  width: 90%;
}

.btn-group .button:hover {
  background-color: #fffff1;
  box-shadow: 0 0px 4px 0 rgba(0,0,0,0.24), 0 0px 32px 0 rgba(0,0,0,0.19);
}

Answer 3

您可以为按钮设置最大宽度。这会将边框限制为您定义的宽度。

.btn-group .button{
    max-width: 20px;
}

你可以放任何值，20px只是一个随机值，你可以根据自己的需要调整。
