Hellow。
我正在使用HTML5和CSS创建一个响应式菜单。为此，我为桌面计算机创建导航菜单，然后使用带有lavel的复选框来显示响应式菜单（我的意思是，显示菜单）。
这是代码：
代码注意:(图片宽度为350px x 100px）：
body {
margin: 0px;
}
/*Strip the ul of padding and list styling*/
ul {
list-style-type: none;
margin: 0;
padding: 0;
position: absolute;
}
/*Hacer que la imagen no se mueva */
#img-nav {
padding-top: 0px !important;
}
/*Create a horizontal list*/
li {
display: inline-block;
float: left;
}
/*Style for menu links*/
li a {
display: block;
min-width: 200px;
height: 70px;
text-align: center;
line-height: 50px;
font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
color: #fff;
background: #2f3036;
text-decoration: none;
padding-top: 30px;
}
/*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*/
li:hover ul a:hover {
background: #19c589;
color: #fff;
}
/*Hide dropdown links until they are needed*/
li ul {
display: none;
}
/*Make dropdown links vertical*/
li ul li {
display: block;
float: none;
}
/*Prevent text wrapping*/
li ul li a {
width: auto;
min-width: 100px;
padding: 0 20px;
}
/*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: 10px 0;
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;
}
#img-nav {
display: none;

问题：
我想要一个全宽度菜单（在PC中），但我不知道该怎么做。
谢谢大家！
答案 0 :(得分：0)
从标签中删除背景并将其放在ul标签上，然后在其上添加css宽度：100％。这个对我很好。
