标头和导航缩放问题

嗨, 我是wordpress的新手, 我想了解更多信息, 我的老板要求我对网站进行一些修改。他想保留我修改过的满足他要求的27个主题。现在我遇到了一些问题：从931到767的宽度, 导航看起来很混乱。我有一堆css添加了一些尝试修复它：

#1

更改填充在媒体查询中(最小宽度：48em), 输出将在单行中。

 @media screen and (min-width: 48em)
    .main-navigation a {
        padding: 1em 0.7em;
    }

#2

我在style.css第3340行中进行了更改：

@media screen and (min-width: 48em) {

to

@media screen and (min-width: 50em) {

并且不得不将其更改为50em而不是790px

@media only screen and (max-width: 790px) {
  body{
     font-size:14px;
  }
   #masthead .navigation-top .wrap{
      z-index:1;
      position: absolute;
      width: 100%;
   }
   .site-content-contain{
      margin-top:1.25em;
   }

}

我认为这不是最好/最干净的解决方案, 但它是可行的。
