在创建我的网站时遇到一个小问题，我的横幅和导航栏之间出现了匿名填充：enter image description here

这是我的代码：

我有办法解决这个问题吗？先感谢您！ 正如我尝试添加padding-top：0px;到导航栏，所以它可以坚持横幅，但它不起作用。我的问题不是重复，因为其他问题是在不同的情况下。

你需要做两件事。 1）将图像上的垂直对齐设置为顶部，以便删除为下降文本元素保留的间隙，以及2）删除<ul>上的边距

＆＃13;
＆＃13; 
@import 'https://fonts.googleapis.com/css?family=Work+Sans:400,500,900';
nav {
  padding-top: 0px;
  position: fixed;
  width: 100%;
  transition: top 0.2s ease-out;
}

.banner {
  text-align: center;
  width: 100%;
  box-shadow: inset 0px -1px 0px 0px rgba(0, 0, 0, 0.13);
}

nav ul#menu {
  padding-left: 0;
  display: flex;
  padding-top: 0px;
}

nav ul li {
  flex-grow: 1;
}

.nav-bar {
  /* Rectangle 1: */
  background: #FFFFFF;
  box-shadow: 0px 2px 2px 0px rgba(0, 0, 0, 0.11), 0px 4px 6px 0px rgba(0, 0, 0, 0.11);
  width: 100%;
  text-align: center;
}

//-------------------------------------------------------

/*Strip the ul of padding and list styling*/

ul {
  list-style-type: none;
  margin: 0;
  position: absolute;
}


/*Create a horizontal list with spacing*/

li {
  display: inline-block;
  float: center;
  margin-right: 1px;
}


/*Style for menu links*/

li a {
  display: block;
  min-width: 140px;

  line-height: 50px;
  font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
  color: #fff;
  background: #2f3036;
  text-decoration: none;
}


/*Hover state for top level links*/

li:hover a {
  background: #19c589;
}


/*Style for dropdown links*/

li:hover ul a {
  background: #f3f3f3;
  color: #2f3036;
  height: 40px;
  line-height: 40px;
}


/*Hover state for dropdown links*/

  padding-left: 0px;
  padding-right: 0px;

}


/*Hide checkbox*/

input[type=checkbox] {
  display: none;
}


/*Show menu when invisible checkbox is checked*/

input[type=checkbox]:checked~#menu {
  display: block;
}


/*Responsive Styles*/

答案 2 :(得分：1)

将其添加到样式中以删除默认边距和填充。

* {
    padding: 0px;
    margin: 0px;
}

答案 3 :(得分：1)

ul是罪魁祸首。您需要将to_invoke添加到margin-top到ul菜单选择器。

要删除微小的差距，如@ j08691所述，请将 nav ul#menu { padding-left: 0; display: flex; padding-top: 0px; margin-top: 0; } 添加到vertical-align: top;班级。
