在以下 CSS

中 
@media screen and (max-width: 750px) {
  .flexbox {
    display: block;
  }
  .menu ul {
    padding-right: 7px;
    padding-top: 7px;
    width: 2140px; /* Should not be a fixed calculated number */
  }
  .menu ul > li {
    box-sizing: border-box;
    margin-right: 0;
    margin-top: 0;
    width: 100px;
    float: left;
  }
}

width: 2140px不应该是固定的计算数字，因为它可能不同。

  <footer>

我已经测试了display: inline-block和其他内容，但没有找到解决方案。

这只能用CSS完成吗？
