我有一个导航标签,它只占我需要的宽度的一半,我需要它占据100%的宽度,但它没有。我看过这个网站,谷歌无法让它像我想要的那样工作。导航即黑色背景应占据宽度的100%,但不是。任何想法。
nav ul ul {
display: none;
}
nav ul li:hover > ul {
display: block;
}
nav ul {
background: #1e1d1d;
background: linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);
background: -moz-linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);

尝试了几个链接并试过宽度:100%,最大宽度:100%;但是我没有运气。

只需将width: 100%; box-sizing: border-box;
添加到nav ul
,就像这样:https://jsfiddle.net/d8ch5qer/
nav ul ul {
display: none;
}
nav ul li:hover > ul {
display: block;
}
nav ul {
background: #1e1d1d;
background: linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);
background: -moz-linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);
background: -webkit-linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);
box-shadow: 0px 0px 9px rgba(0, 0, 0, 0.15);
padding: 0 20px;
border-radius: 10px;
list-style: none;
position: relative;
display: inline-table;
width: 100%;
box-sizing: border-box;
}
nav ul:after {
content: "";
clear: both;
display: block;
}
nav ul li {
float: left;
}
nav ul li:hover {
background: #f7f7f7;
background: linear-gradient(top, #f7f7f7 0%, #5f6975 40%);
background: -moz-linear-gradient(top, #f7f7f7 0%, #5f6975 40%);
background: -webkit-linear-gradient(top, #f7f7f7 0%, #5f6975 40%);
}
nav ul li:hover a {
color: #ff0000;
}
nav ul li a {
display: block;
padding: 25px 40px;
color: #f7f7f7;
text-decoration: none;
}
nav ul ul {
background: #f7f7f7;
border-radius: 0px;
padding: 0;
position: absolute;
top: 100%;
}
nav ul ul li {
float: none;
position: relative;
}
nav ul ul li a {
padding: 15px 40px;
}
nav ul ul li a:hover {
background: #888484;
color: #ff0000;
}
nav ul ul ul {
position: absolute;

top: 0;

添加:
nav ul {
width: 100%;
display:block;
}
但即便如此,管理列以适应所有宽度也会遇到问题。您可以使用JS计算每个宽度,或者为导航使用 display:table ,为 ul li使用 display:table-cell 强>
答案 2 :(得分:0)
如果您正在使用Chrome浏览器,Chrome会在<ul>
中添加40px的填充内容:
-webkit-padding-start: 40px;
这使<ul>
扩展到您定义的宽度。
有两种方法可以克服这个问题:
<强> 1。删除所有填充,包括浏览器默认值
https://jsfiddle.net/pzod450b/1/
只需添加-webkit-padding-start: 0
即可。最重要的是,你还在<ul>
的任一侧添加了20px的填充,删除了这个
CSS:
nav ul {
background: #1e1d1d;
background: linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);
background: -moz-linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);
background: -webkit-linear-gradient(top, #1e1d1d 0%,#bbbbbb 100%);
box-shadow: 0px 0px 9px rgba(0,0,0,0.15);
border-radius: 10px;
list-style: none;
position: relative;
display: inline-table;
width: 100%;
}
<强> 2。使用box-sizing: border-box
使用此方法将确保浏览器计算应用于其最终宽度内元素的所有填充/边框:
https://jsfiddle.net/u1vzag3b/
nav ul {
background: #1e1d1d;
background: linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);
background: -moz-linear-gradient(top, #1e1d1d 0%, #bbbbbb 100%);
background: -webkit-linear-gradient(top, #1e1d1d 0%,#bbbbbb 100%);
box-shadow: 0px 0px 9px rgba(0,0,0,0.15);
border-radius: 10px;
list-style: none;
position: relative;
display: inline-table;
width: 100%;
box-sizing: border-box;
}
您会注意到,在这两种情况下,都应将width: 100%
添加到nav ul
。
