我想创建一个全宽导航,左侧是页面徽标,这是一个链接并链接回家。还有一个注册/登录和购物车li元素。
我想将100%的背景色也放在屏幕上。它们也需要内联。
使用HTML5标签你怎么能在语义上做到这一点。什么是元素的层次结构?
你将如何实现这一目标。
header{
width: 100%;
background-color: #000000;
margin: 0 ;
padding: 0;
}
header h1{
margin: 0;
padding: .5em 0;
color: black;
clear:both;
}
header li:nth-child(1){
float: left;
}
header li:nth-child(n+2){
text-align: right;
display: inline;
}

你可以向左移动一些元素,向右移动一些元素来实现这一点。
<header class="global-header">
<div class="inner-w">
<a href="#" class="site-logo">
<img src="http://placehold.it/100x100" alt="" />
</a>
<nav class="account-nav">
<a href="#">login</a>
<a href="#">whatever</a>
</nav>
</div>
</header>
.global-header {
background: #f06;
padding: 1em;
overflow: hidden;
}
.global-header .inner-w {
max-width: 700px; /* or 960 or whatever */
margin-right: auto;
margin-left: auto;
}
.global-header .site-logo {
float: left;
}
.account-nav {
float: right;
}
.account-nav a {
display: inline-block;
vertical-align: middle;
border: 1px solid red;
}

我不确定我完全理解你的问题。根据我的理解,您正在尝试为网页顶部创建一个导航栏,并且您希望它具有链接徽标和一些列表元素。
基于这个假设,我强烈建议您查看Bootstrap。 Bootstrap是Twitter制作的前端框架,用于制作优雅,响应迅速的Web项目。首先查看文档here。文档包括下面的示例,这是一个导航栏,其中包含您在导航栏中可能需要的任何内容。请注意,如果要使用Bootstrap组件,则需要将引导脚本添加到页面中。查看他们的"Getting Started" page了解更多信息。
