如何使用显示在同一行上对齐页眉？

问题描述

我使用display: flex;对齐了对象，现在我尝试使用text-align: justify;和display: block;将标头放在同一行上，但是仍然无法正常工作。我究竟做错了什么。有人可以帮忙吗？

.pos-container {
  list-style: none;
  padding-top: 40px;
  padding-bottom: 60px;
  display: block;
}

.pos-info {
  display: inline-flex;
  float: left;
}

.pos-info: before {
  display: block;
  height: 1px;
  background-color: #045d71;
  content: " ";
  width: 90%;
  margin: 0 auto;
}

.pos-image {
  border-radius: 3px;
  width: 47%;
  height: 50%;
}

.pos-container i {
  font-size: 180%;
  color: #07a0c3;
  margin-top: 150px;
  margin-left: 40px;
  display: block;
}

.pos-info h3 {
  display: inline-block;
  font-size: 110%;
  text-align: left;
  margin-left: 40px;
  float: left;
  column-width: auto;
}

.pos-content {
  display: flex;
  text-align: justify;
  margin-top: 69px;
  float: right;
  margin-left: -118px;
  margin-bottom: 80px;
}

.pos-content: after {
  display: block;
  height: 0.1px;
  background-color: #045d71;
  content: " ";
  width: 90%;
  margin: 0 auto;
}

<div class="row">
  <ul class="pos-container">
    <li class="pos-info">
      <img class="pos-image" src="resources/img/cashier2.jpg" alt="pos picture">
      <i class="ion-arrow-left-b"></i>
