跨不同屏幕类型的网页显示

Question

我正在尝试使网页在所有屏幕类型上统一，这是代码片段，这是标题...

@import url('(https:fonts.googleapis.com/css?family=Poppins:300,400,500,600,700,800,900&display=swap)');

/* Global Styles */
* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

body {
  font-family: 'Poppins', sans-serif;
  background-color: #f0f0f0;
}

/* Header Styles */
header {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  padding: 30px 100px;
  display: flex;
  justify-content: space-between;
  align-items: center;
  background-color: #333;
  color: #fff;
}

header .logo {
  position: fixed;
  color: #fff;
  font-weight: 700;
  text-decoration: none;
  font-size: 2em;
  text-transform: uppercase;
  letter-spacing: 2px;
}

header ul {
  position: fixed;
  display: flex;
  justify-content: center;
  align-items: center;
}

header ul li {
  list-style: none;
  margin-right: 20px;
}

header ul li a {
  text-decoration: none;
  padding: 6px 15px;
  color: #fff;
  border-radius: 20px;
}

header ul li a:hover {
  background: #fff;
  color: #333;
}

  }
  
  header ul li a:hover {

    color: #333;
  }
  
  .nav-links {
    display: block;
    margin-bottom: 20px;
  }
}


/* Tablets and Small Laptops (481px to 768px) */
@media only screen and (min-width: 481px) and (max-width: 768px) {
  header {
    padding: 25px 75px;
  } 
}

<header>
  <a href="#" class="logo">LOGO</a>
  <ul>
    <li><a href="#">Home</a></li>
    <li><a href="search.html">Search</a></li>
    <li><a href="videos.html">Videos</a></li>
  </ul>
</header>

加入了响应式设计代码，但似乎效果并不完美……不同的元素已被编辑，但屏幕缩小后似乎并没有完美的结果。很高兴获得对此的评论和帮助

Answer 1

仔细查看代码后，我发现了一些问题。首先，您使用了太多

position: fixed;

，这通常不利于响应式网页设计。其次，您在

media

查询中使用了重复的代码。对于响应式设计，您应该只在

media

查询中使用更新的属性，并且不需要使用整个代码，而不仅仅是更新的属性。我为其提供了更新的代码。希望对你有帮助。
