<div class="sub-title">招租相关信息</div>





.sub-title {
  font-size: 16px;
  text-align: left;
  color: #314790;
  font-weight: 700;
  position: relative;
  padding-left: 10px;
  margin-bottom: 20px;
}

.sub-title::before {
  content: "";
  background-color: #3796ec;
  width: 3px;
  height: 18px;
  position: absolute;
  left: 0;
  top: 50%;
  margin-top: -9px;
  border-radius: 3px;
}

下面是 错误做法:  14号字体时能对齐 ,调整了字体大小 就无法对齐
