Answer 1

将.four的css更改为：

.four {
  width: 246px;
  height: 138px;
  margin: 0 auto;
  position: relative;
}

.one {
  width: 100%;
}

.two {
  margin: 0;
  padding: 0;
  border: 0;
  background: transparent;
  float: left;
  position: relative;
  width: 100%;
  margin-bottom: 15px;
}

.three {
  float: left;
  list-style: none;
  color: #333;
  font-size: 19px;
  width: 100%;
  background: #fff;
  border: 1px solid #ccc;
  padding: 10px 0px;
}

.four {
  width: 246px;
  height: 138px;
  margin: 0 auto;
  position: relative;
}

.five {
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  height: 100%;
  margin-left: auto;
  margin-right: auto;
  overflow: hidden;
  display: block;
  cursor: pointer;
}

.six {
  transform: translateY(-50%);
  top: 50%;
  left: 0;
  background-color: transparent;
  display: block;
  position: absolute;
}

.seven {
  width: 246px;
  display: block;
  margin: 0 auto;
  max-width: unset;
}

<div class="one">
  <ul class="two">
    <li class="three">
      <div class="four">
        <a class="five" href="">
          <div class="six">
            <img class="seven" src="http://kawamono.com/img/cms/Hobby/Coin%20Bank/x100828-sanrio-hellokitty-mini-bank-ylw-SET.jpg.pagespeed.ic.iSCJA9hZBG.jpg">
          </div>
        </a>
      </div>
    </li>
  </ul>
</div>

我注意到您想要使用float:left .four来对图像居中，这与您期望的结果相冲突。我将您的边距更改为margin:0 auto;以正确地将其水平居中

Answer 2

您可以添加：

width: 100%;

为.four和.six设置样式，这会使图像侧向居中。那些div没有搭配，所以图像不会居中。
