Question

.dropdown:hover .dropbtn{...}中的转换正在改变页面大小，当.nav li a:hover {...}上的悬停没有做好时。我试图改变位置，但它没有帮助。我不知道还能做些什么来解决这个问题。

＆＃13;

html, body {
  margin: 0;
  padding: 0;
}

.container {
  max-width: 940px;
  margin: 0 auto;
  padding: 5px;
}

.header {
  background-color: #333;
}

.nav {
  list-style-type: none;
  margin: 0;
  padding: 20px 0;
  letter-spacing: 2.6px;
}

.nav li {
  display: inline-block;
}

.nav li a {
  text-decoration: none;
  color: #fff;
  font-family: 'Raleway', sans-serif;
  font-weight: 600;
  font-size: 12px;
  margin-right: 25px;
  text-transform: uppercase;
}

.dropdown {
    background-color: #333;
    position: relative;
    display: inline-block;
  }

.dropbtn {
    text-decoration: none;
    background-color: #333;
    color: #fff;
    font-family: 'Raleway', sans-serif;
    font-weight: 600;
    font-size: 12px;
    margin-right: 25px;
    border: none;
    cursor: pointer;
    text-transform: uppercase;
    letter-spacing: 2.6px;
  }

.dropdown-content {
    display: none;
    position: fixed;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    z-index: 1;
  }

.dropdown-content a {
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;
  }

.dropdown-content a:hover {background-color: #f1f1f1}

.dropdown:hover .dropdown-content {
  display: block;
}

.dropdown:hover .dropbtn {
background-color: #ffffff;
color: #333;
transition: 0.6s;
padding: 24px 10px;
}

.nav li a:hover {
  transition: 0.6s;
  background-color: #ffffff;
  color: #333;
  font-weight: 900;
  padding: 24px 10px;
  font-size: 12px;
  cursor: pointer;
}

Answer 2

请注意实际的变化是......

来自：<button class="dropbtn" href ="indexKontakt.html"> Produkty </button>

于：<a class="dropbtn" href="indexKontakt.html"> Produkty </a>

应该指出的是那个班级＆＃39; dropbtn＆＃39;应该删除，并通过ul li和a元素完成样式。

还应该注意，可以避免在ul li中嵌套div，并且在他们自己的div容器中通常不需要顶级下拉。

我相信这会更有帮助，因为它有助于了解错误或问题。

当.dropdown悬停{}时，转换正在改变页面的大小
