您可以这样使用 flexbox

.row {
  box-sizing: border-box;
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-flex: 0;
  -ms-flex: 0 1 auto;
  flex: 0 1 auto;
  -webkit-box-orient: horizontal;
  -webkit-box-direction: normal;
  -ms-flex-direction: row;
  flex-direction: row;
  -ms-flex-wrap: wrap;
  flex-wrap: wrap;
  margin-right: -.5rem;
  margin-left: -.5rem;
}

.col {
  -webkit-box-flex: 1;
  -ms-flex-positive: 1;
  flex-grow: 1;
  -ms-flex-preferred-size: 0;
  flex-basis: 0;
  max-width: 100%;
}

.list {
  position:relative;
  display:block;
  padding:0;
}
.list li{
