最后一行不可见

Question

我有一个网站，其中最后2-3行由于页脚而不可见。

页脚编码

.footer {
  overflow: hidden;
  background-color: gold;
  position: fixed;
  bottom: 0;
  width: 100%;
}

.footer a {
  float: left;
  display: block;
  color: #f2f2f2;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
  font-size: 17px;
}

请帮帮我！
