我正在尝试使用 HTML 和 CSS 创建导航栏。但是，导航栏并没有像我希望的那样延伸到页面末尾。我试过使用 padding-left-: 0px 和 padding-right: 0px; 但这不起作用。

这是我目前的工作:

$banner-height: 50px;
@import 'https://fonts.googleapis.com/css?family=Work+Sans:400,500,900';

nav {
  height: $banner-height * 2;
  position: fixed;
  width: 100%;
  top: 0;
  transition: top 0.2s ease-out;
}

.banner {
  text-align: center;
  line-height: $banner-height;
  top: 0;
  width: 100%;
  background: #FEFFB7;
  box-shadow: inset 0px -1px 0px 0px rgba(0,0,0,0.13);
}

.nav-bar {
  top: $banner-height;
  /* 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%;
  line-height: $banner-height;
  text-align: center;
}

.nav-up {
  top: -$banner-height;
}

	//-------------------------------------------------------
	/*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;
    height: 50px;
    text-align: center;
    line-height: 50px;

    color: #fff;
    background: #2f3036;
    text-decoration: none;
}

li:hover a {
    background: #19c589;
}
/*Style for dropdown links*/
li:hover ul a {

}

}

}
/*Make dropdown links vertical*/

    display: block;
    float: none;
}
/*Prevent text wrapping*/
li ul li a {
    width: auto;
    min-width: 100px;
   	padding-left: 0px;
		padding-right: 0px;
}
/*Display the dropdown on hover*/
ul li a:hover + .hidden, .hidden:hover {
    display: block;
}
/*Style 'show menu' label button and hide it by default*/
.show-menu {
    font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
    text-decoration: none;
    color: #fff;
    background: #19c589;
    text-align: center;
   	padding-left: 0px;
		padding-right: 0px;
    display: none;
}
/*Hide checkbox*/
input[type=checkbox]{
    display: none;
}
/*Show menu when invisible checkbox is checked*/
input[type=checkbox]:checked ~ #menu{
    display: block;
}
/*Responsive Styles*/
@media screen and (max-width : 760px){
    /*Make dropdown links appear inline*/
    ul {
        position: static;
        display: none;
	
    }
    /*Create vertical spacing*/
    li {
        margin-bottom: 1px;
    }
    /*Make all menu links full width*/
    ul li, li a {
        width: 100%;
    }
    /*Display 'show menu' link*/
    .show-menu {
        display:block;
    }
}

最佳答案

已更新:代码段、flexbox 和 padding 中的解决方案留给 UL 设置为 0。

看到一些与嵌入代码段不一致的行为，所以这里是一个 fiddle :

$banner-height: 50px;
@import 'https://fonts.googleapis.com/css?family=Work+Sans:400,500,900';

nav {
  height: $banner-height * 2;
  position: fixed;
  width: 100%;
  top: 0;
  transition: top 0.2s ease-out;
}

.banner {
  text-align: center;
  line-height: $banner-height;
  top: 0;
  width: 100%;
  background: #FEFFB7;
  box-shadow: inset 0px -1px 0px 0px rgba(0,0,0,0.13);
}

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

nav ul li {
   flex-grow: 1;
   }

.nav-bar {
  top: $banner-height;
  /* 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%;
  line-height: $banner-height;
  text-align: center;
}

.nav-up {
  top: -$banner-height;
}
